### 1. Conclusion and termination of the contract

#### 1.1. Conclusion of the contract

1.1.1. The contract for the use of sipgate services comes into effect when sipgate accepts the customer's order for the provision of the services. Acceptance shall be deemed declared by sipgate ten calendar days after receipt of the customer's order, provided that the sipgate connection and sipgate account have been activated by that time. The customer shall be bound to their application for 5 working days.

1.1.2. The details regarding the contract term are primarily determined by the service description sipgate. Unless otherwise specified there, the contract has no minimum term.

#### 1.2. Ordinary termination

1.2.1. The details regarding the notice period are primarily determined by the service description sipgate. Unless otherwise specified there, the contract may be terminated by either party with one calendar day's notice to the end of the month.

1.2.2. Terminations must be made by email or in writing (letter or fax).

#### 1.3. Extraordinary termination

1.3.1. sipgate reserves the right to extraordinary termination for good cause. Good cause exists in particular if the customer culpably breaches their obligations under the contractual relationship and it is unreasonable for sipgate to wait until the expiry of the notice period. Such a case exists, among others, if the customer:

* creates a sipgate account under a false name or false identity and/or
* uses the sipgate account, the connection, or the assigned phone number abusively and/or
* insolvency proceedings are opened over the customer's assets or the customer files an application for the opening of insolvency proceedings and/or
* chargebacks occur after direct debits.

1.3.2. Furthermore, sipgate is entitled to an extraordinary right of termination in the event of a change in the legal basis of this contract, orders and/or directives relating to the contract issued by authorities, courts or other public bodies, provided that this makes it unreasonable for sipgate to remain bound by the contract.

1.3.3. The customer's statutory right to extraordinary termination for good cause remains unaffected.

#### 1.4. sipgate credit upon termination of the contract

1.4.1. If the customer has a credit balance on their sipgate account at the time the termination takes effect, sipgate undertakes to reimburse this to the customer upon corresponding request. The customer can submit the request via their sipgate account. The reimbursement by sipgate is made by way of a credit to the specified bank or credit card account of the customer.

1.4.2. Any other reimbursement of sipgate credit is excluded.

#### 1.5. Inactive accounts

If the customer has a sipgate account that has not been used for more than one year (inactive account), sipgate is entitled to delete the sipgate account. sipgate will first inform the customer of the intended deletion via the email address stored in the sipgate account. If the customer does not object within 4 weeks, sipgate will delete the customer's sipgate account.

### 2. Customer's obligations to cooperate

2.1. The customer is responsible for maintaining an Internet access suitable for use with sipgate (see requirements for use – Internet access). If this is not the case, the mutual performance obligations arising from the contractual relationship remain unaffected.

2.2. The customer must take all necessary and customary security measures against unwanted and abusive use of their sipgate connection by third parties. If the customer identifies unwanted or abusive use, they must inform sipgate immediately.

2.3. sipgate processes essential communication matters (including those relevant to the contract) via email. The customer undertakes to provide a valid email address of their own when registering with sipgate and to check it regularly, as well as to inform sipgate immediately of any changes to their email address.

2.4. If changes occur that affect the flow of communication or the contractual relationship between the customer and sipgate, sipgate must be informed immediately. This notification obligation applies in particular to the following points:

* Change of the customer's place of residence/company headquarters (among other things necessary for the correct localization of emergency calls). Further information at: [Information on placing emergency calls](http://www.sipgate.de/team/nutzungsbedingungen#emergency_call)
* Change of the customer's email address
* for payments in the autoprepay procedure, the bank details and credit card information.

2.5. The customer may use the connections to sipgate only as intended and in accordance with the (telecommunications) laws and regulations in their respectively applicable version. The customer is obliged not to misuse the telecommunications services offered by sipgate for purposes that conflict with statutory provisions, the relevant [service description sipgate](https://www.sipgate.de/leistungsbeschreibung) or the sipgate Terms and Conditions.

2.6. The customer undertakes not to use any equipment or run any applications that may lead to changes in the physical or logical structure of the network provided by sipgate.

2.7. The customer undertakes to keep access data for their sipgate account and user accounts, as well as access data for sipgate's VoIP service (user password or SIP ID and SIP password), confidential and secure and not to disclose them to third parties. If the customer has legitimately disclosed access data to third parties (e.g. their employees), they must inform them of the obligation to keep the access data confidential and secure and oblige them accordingly.

Private customers in tariffs with multiple users (upgrade to business S, L, XL) may only pass on the contractual services to persons in their own household.

2.8. The customer agrees that their phone number may be transferred to a network operator other than the one used at the time the contract was concluded. This entails no costs and no disadvantages for the customer, and the contract between sipgate and the customer remains unaffected.

2.9. sipgate is entitled to change the customer's phone numbers

* if the customer agrees to the change,
* if this is required by legal provisions or official measures (in particular the Telecommunications Numbering Ordinance or decisions of the Federal Network Agency),
* or if there are corresponding economic or legal constraints that sipgate cannot resolve otherwise with reasonable effort.

2.10. The customer is not permitted to pass on sipgate services provided to them to third parties in a commercial manner without sipgate's consent.

2.11. If there is abuse by the customer or by a user authorized by them (e.g. violations of 2.5, 2.6, 2.10 or comparable violations) and the customer does not stop the abuse within a reasonable period despite sipgate's request, sipgate is entitled to block their sipgate connection or – where applicable – delete user accounts created by the customer. If the customer is responsible for the blocking or deletion, sipgate will charge the customer for the costs of the blocking/deletion. The customer is obliged to pay the basic fees incurred during a blocking if they are responsible for the blocking.

### 3. Connection charges

3.1. The customer is obliged to pay for any use of their connection for which they are responsible.

3.2. The customer is also obliged to pay the charges incurred by the user or co-user. This also applies in cases of abusive use, unless the customer proves that they are not responsible for any breach of duty.

3.3. The obligation to pay remuneration does not apply if facts justify the assumption that third parties have influenced the charged connection fee through unauthorized changes to public telecommunications networks.

3.4. The fees for the VoIP service are determined by the price list applicable at the beginning of each individual connection for the product selected by the customer according to the service description sipgate. The current price list can be viewed online at any time via the respective current link.

### 4. Billing and payment

#### 4.1. Billing methods

sipgate distinguishes between three different billing methods: prepay, autoprepay and postpay.

4.1.1. Prepay method: Under this procedure, the customer first pays an amount determined by them to sipgate (sipgate credit) and can only use chargeable sipgate products after payment has been received, in accordance with their sipgate credit. Possible payment methods are bank transfer, direct debit and credit card. Unused sipgate credit does not expire.

4.1.2. Autoprepay method: Autoprepay is identical to the prepay method, except that the customer's sipgate credit is automatically topped up when it falls below a minimum amount set by the customer. Possible payment methods for autoprepay are direct debit and credit card. Unused sipgate credit does not expire.

4.1.3. Postpay method: sipgate reserves the right to offer the customer payment only after performance by sipgate on the basis of an appropriate invoice.

4.1.4. If the service description for the contract booked by the customer provides for the autoprepay method as the billing method, the customer must ensure that their current bank details or credit card details are stored in their sipgate account. If this is not the case, or if the customer revokes the direct debit authorization or the authorization to charge the credit card, a negative balance (a claim by sipgate against the customer) may result from telephone calls or monthly fees. In this case, sipgate is entitled to request the customer by email to settle their negative balance.

#### 4.2. Payment methods

4.2.1. In addition to bank transfers, sipgate also offers direct debit and credit card payments, provided the customer gives their consent. However, participation in the autoprepay method is only possible if the customer gives consent to recurring direct debit or credit card payments. The customer must declare this consent when activating the autoprepay billing method in their account or in writing or by email to sipgate. If charging the selected payment method is unsuccessful, sipgate is entitled to fall back on alternative payment methods stored in the account.

4.2.2. The pre-notification period for SEPA direct debits is one day.

4.2.3. For returned direct debits or collections, the customer must reimburse the costs incurred, insofar as they are responsible for these. sipgate will charge the customer for the costs arising in connection with the rejection (third-party fees of the customer's bank and fees of sipgate's bank) and collect them from the account balance, unless the customer proves that no damage or damage of significantly lesser amount has occurred at all.

4.2.4. If, in exceptional cases, the customer pays by another method, for example in the event of late payment due to a returned direct debit or insufficient funds, settlement shall only occur if the customer has sufficiently specified the intended purpose of the payment (in particular the invoice number or a comparable, unambiguous booking code from sipgate) when making the payment. This applies accordingly to payments by third parties.

4.2.5. sipgate reserves the right to offer the customer additional payment methods (e.g. PayPal) in addition to direct debit or credit card payments.

#### 4.3. Form of the invoice

4.3.1. sipgate issues invoices exclusively as PDF files by email or for download. It is not possible to receive an invoice in paper form.

4.3.2. The customer agrees to receive their invoice by email and is informed that confidential data transmission over the Internet cannot be guaranteed. For this reason, sipgate invoices do not contain itemized connection records. These can be retrieved separately by the customer.

4.3.3. The mandatory information in the invoice (Section 14 (4) UStG) is included in the invoice on the basis of the information provided by the customer in their sipgate account. The customer is obliged to keep this information up to date. sipgate is not obliged to create invoices that deviate from this information.

#### 4.4. Due date and default

4.4.1. Claims for ongoing contracts that arise at monthly intervals (or at other regular intervals) are due on the 1st day of each month (or period), unless otherwise stipulated in the service description. Claims that do not arise at regular intervals become due upon receipt of the invoice by the customer.

4.4.2. The statutory provisions apply to default.

4.4.3. If the customer is in default, sipgate is entitled to block the service in accordance with Section 61 (3) et seq. TKG.

4.4.4. If the customer is a consumer (within the meaning of Section 13 BGB) and is in default, interest will be charged at five percentage points above the European Central Bank's respective base rate. If the customer is an entrepreneur (within the meaning of Section 14 BGB), eight percentage points above the base rate will be charged. sipgate reserves the right to assert further claims due to late payment (e.g. reminder fees).

4.4.5. Eight weeks after receipt of the invoice, sipgate is entitled to delete the connection data underlying the invoice, which is why subsequent objections can no longer be considered. This also applies accordingly if the customer requests the early deletion of the connection data from sipgate. A complete review of the invoice is therefore only possible as long as the customer's connection data is stored in full.

4.4.6. The customer may only offset claims against sipgate GmbH with claims that have been legally established or are undisputed.

#### 4.5. Objections

4.5.1. The customer must carefully check sipgate's invoices. The customer must raise objections to the amount of the invoice in writing no later than eight weeks after receipt of the invoice.

If the customer has credit with sipgate against which sipgate offsets basic fees and call charges, objections to the offsetting must, notwithstanding sentence 1, be raised no later than eight weeks after the end of the month in which the charges were incurred. The amount of the offsetting amounts can be found in the itemized connection record.

Raising objections does not affect the due date of the invoice amount.

4.5.2. Objections to the invoice or to the offsetting against credit are excluded insofar as the relevant traffic data have already been deleted within the statutory periods (eight weeks) or at the customer's express request before the objections are raised.

4.5.3. If objections are not raised within the period of eight weeks under No. 4.5.1, the invoice/offsetting against credit shall be deemed approved by the customer. sipgate points out this legal consequence in the invoices.

4.5.4. In the event of justified objections raised in due time, any overpayment shall first be offset against outstanding payment claims of sipgate. If no outstanding payment claims exist, a credit note shall be issued.

### 5. Data protection

5.1. The legal basis for the handling of the customer's personal data includes, among others, the General Data Protection Regulation (GDPR), the Federal Data Protection Act (BDSG), the Telecommunications Act (TKG), and the Telecommunications and Telemedia Data Protection Act (TTDSG). Personal data is collected, processed or used only if the data subject has consented or if the TTDSG or another legal provision orders or permits it.

5.2. Data processing is therefore particularly permissible insofar as it is necessary. It is necessary for the establishment and design of the contractual relationship (customer master data), for the provision of telecommunications services (connection data), and for their billing (billing data).

5.3. sipgate maintains telecommunications secrecy in accordance with the statutory requirements.

5.4. Detailed information on the handling of personal data by sipgate can be found in our [Privacy policy](http://www.sipgate.de/team/datenschutz) , which is also part of the sipgate Terms and Conditions.

5.5. The customer commissions sipgate to maintain a monthly itemized connection record, which they can access via the administrator account. This record lists all chargeable connections individually, including the date, destination number, start and duration of the connection, and the charge for the individual connection. The phone numbers of the connections are either shortened to the last three digits or shown in full length, depending on the customer's choice. The customer can also completely deactivate the itemized connection record in their administrator account. If the customer does not exercise their right of choice, an unabridged listing will be provided.

The customer undertakes to inform all current and future co-users of their sipgate account or, in the case of business use, all current and future employees without delay and to comply with the co-determination rules.

5.6. The customer commissions sipgate to store the key data (time, duration) of telephone calls, faxes and SMS messages sent or received via sipgate, independently of the itemized connection record, for the call list/event list and to make it available to the respective user on their user web interface.

5.7. sipgate deletes customer data if the customer issues a corresponding instruction, but only insofar as this is permitted under the TKG or other legal provisions. If objections have been raised, sipgate is entitled to retain the traffic data until the objections have been finally resolved.

### 6. Liability

6.1. sipgate's liability for financial losses is limited to a maximum of €12,500.00 per customer. With respect to all customers as a whole, liability is limited to €30 million per single act or per single damaging event. If the amounts payable to several customers due to the same event exceed the maximum limit, compensation shall be reduced in the proportion that the total of all claims for compensation bears to the maximum limit. The limitation of liability does not apply if the damage was caused intentionally.

6.2. Liability for consequential costs resulting from emergency calls outside the specified place of residence or business is excluded.

6.3. Otherwise, sipgate is only liable for gross negligence or intent, unless it concerns the breach of an essential contractual obligation (so-called cardinal obligation). In the event of a slightly negligent breach of a cardinal obligation, liability is limited to such typical contractual damages as were reasonably foreseeable at the time the contract was concluded.

6.4. sipgate's liability for warranted characteristics as well as under the provisions of the Product Liability Act and for personal injury (life, body, health) remains unaffected by the above provisions.

6.5. Insofar as sipgate's liability is effectively excluded or limited, this also applies to the personal liability of sipgate's employees, other staff, organs, representatives and vicarious agents.

6.6. sipgate's obligation to perform shall apply only if sipgate itself has been supplied in accordance with the contract and on time with the corresponding advance services and has not breached any due diligence obligations in this respect. In the event of service disruptions caused by force majeure, sipgate shall in any case be released from the obligation to perform.

### 7. Liability for the use of AI applications by customers

7.1. sipgate provides AI applications that customers can use for automated communication with their end customers (e.g. initial telephone contact by AI agents). The systems comply with the requirements of the EU AI Act and are regularly checked for functionality and legal compliance. AI systems are highly complex systems that are subject to continuous development. Incorrect, unwanted or misleading results therefore cannot be ruled out, even if the AI system operates within its specific specifications.

7.2. sipgate is not liable for damage caused by the use of the AI applications in the relationship between the customer and their end customers, provided that sipgate has properly provided and documented the systems. In particular, sipgate assumes no liability for incorrect information, misunderstandings or omitted notices caused by the AI in customer contact.

7.3. The customer is obliged to check the AI applications for their suitability for the respective use case before productive use and to ensure that the legal obligations to provide information, transparency and documentation towards their end customers are fulfilled.

7.4. sipgate is liable only in the event of intentional or grossly negligent conduct and in the event of a breach of essential contractual obligations. Any further liability, in particular for indirect damages or loss of profit, is excluded.

7.5. The customer shall indemnify sipgate against all claims by third parties asserted in connection with the use of the AI applications vis-à-vis end customers, provided that these are not based on a breach by sipgate of statutory or contractual obligations.

### 8. Changes to fees, the General Terms and Conditions (GTC) and the service description

8.1. sipgate charges the customer the fees applicable at the time the contract is concluded and is generally bound by them. The agreed fees may only be increased by sipgate with effect for the future in the following cases:

* in the event of changes to the VAT rate, sipgate is entitled to adjust the fees in line with the change,
* if the Federal Network Agency or another authority mandatorily requires an increase in fees, sipgate may change the fees in accordance with the requirements and,
* if third parties from whom sipgate obtains necessary upstream services for the provision of the services owed under this contract increase their prices, sipgate may pass on this price increase to the customer.

A prerequisite for sipgate increasing the fees is that sipgate notifies the customer of the change in fees by email at least six weeks before it takes effect and explains the reason for the increase.

8.2. If the customer is a consumer (within the meaning of Section 13 BGB), the customer has an extraordinary right of termination in the event of an increase in net fees, which becomes effective at the time of the relevant fee change. If the customer does not exercise this right of termination within four weeks of receiving notice of the fee increase, the change shall be deemed approved. sipgate will expressly point this out again in the notification of the fee increase.

In the event of changes to VAT, sipgate is entitled to adjust the fees in line with the change without this giving rise to a right of termination for the customer.

8.3. If the customer is an entrepreneur (within the meaning of Section 14 BGB), sipgate is entitled, irrespective of No. 8.1, at its reasonable discretion and taking into account general market developments (in particular also internal upstream service prices), to adjust the fees at any time with effect for the future. This applies in particular if sipgate's purchase prices change.

8.4. sipgate is entitled to amend these Terms and Conditions insofar as this does not affect essential provisions of the contractual relationship and is necessary to adapt to developments that were not foreseeable at the time the contract was concluded and the failure to take which into account would noticeably disrupt the balance of the contractual relationship. Essential provisions are in particular those concerning the type and scope of the contractually agreed services and the term, including the provisions on termination.

Furthermore, amendments or supplements to the Terms and Conditions may be made insofar as this is necessary to remedy difficulties in the performance of the contract due to regulatory gaps that arose after the contract was concluded. This may be the case in particular if case law changes and one or more clauses of these Terms and Conditions are affected by this. If the change results in a deterioration for the customer, a change is only permissible on the condition that sipgate notifies the customer of this by email at least six calendar weeks before it takes effect.

8.5. The service description may be amended if this is necessary for good cause, the customer is not placed at a disadvantage compared with the service description included at the time the contract was concluded (e.g. retention or improvement of functionalities), and it does not deviate significantly from it. Good cause exists if there are technical innovations on the market for the services owed or if third parties from whom sipgate obtains necessary upstream services for the provision of its services change their service offerings. If the change results in a deterioration for the customer, a change is only permissible on the condition that sipgate notifies the customer of this by email at least six calendar weeks before it takes effect.

8.6. Planned changes to the Terms and Conditions and the service description under clauses 8.5 and 8.6 will be notified to the customer by email at least six weeks before they take effect. If the change to the Terms and Conditions or the service description is disadvantageous for the customer, the customer has an extraordinary right of termination at the time the changes take effect. If the customer does not terminate in writing or by email within four weeks of receipt of the notice of change, the changes shall become part of the contract at the time they take effect. The customer will be expressly informed of this consequence in the notice of change.

### 9. Maintenance and fault clearance service

sipgate offers its customers the opportunity at any time to access frequently asked questions and their answers as well as various configuration instructions via its help center, and to contact customer support in writing via the contact form or by telephone, for example to report faults.

### 10. Final provisions

10.1. Any deviating General Terms and Conditions of the customer shall not apply, even if sipgate does not expressly object to them.

10.2. Free additional services provided by sipgate are not part of the contract. sipgate may change and/or discontinue these services at its own discretion. This is subject to any other agreements with the customer.

10.3. The customer may only transfer the rights and obligations arising from this contract to a third party with sipgate's prior written consent.

10.4. The use of products and services of sipgate GmbH within the territory of or by citizens of the United States of America (USA) is excluded.

10.5. The use of sipgate is excluded in those countries in which the use of the sipgate service is not permitted.

10.6. The law of the Federal Republic of Germany shall apply exclusively between the customer and sipgate, as it applies between domestic persons excluding the UN Convention on Contracts for the International Sale of Goods, unless mandatory law prescribes the applicability of another legal system.

10.7. The place of jurisdiction is Düsseldorf, insofar as the customer is a merchant.

10.8. sipgate is entitled to transmit the customer's master data to third parties insofar as this is necessary for the purpose of assignment or collection of claims. Any legally permissible transmission of further customer data for the purpose of debt collection remains unaffected.

10.9. sipgate is entitled to provide the services through third parties as subcontractors.

10.10. Locations created in the sipgate account are checked using a suitable procedure.

### 11. Customer information pursuant to the Telecommunications Act (TKG)

#### 11.1. Emergency call (fixed line)

The emergency numbers 110 and 112 can be reached via sipgate. These are activated for your stored address. The customer must regularly check whether the personal or business details are correct and, if necessary, change them.

Only if the name and address are correct at the time an emergency call is placed can proper emergency call functionality, in particular reaching the nearest fire or police station, be guaranteed. If you use sipgate from a location other than the stored address (nomadic use), emergency service may not be available at all, or only if you can tell the emergency center your location and your name. So-called "gasping calls" are not possible.

#### 11.2. Emergency call (mobile network)

In Germany, an emergency call to the Europe-wide emergency number 112 and to the national emergency number 110 used in Germany can only be made with an inserted and valid SIM card. Other regulations may apply outside Germany. In the event of an emergency call to 112 and 110, information about the caller's location may also be transmitted to the responsible emergency call answering point. In addition to the general emergency numbers 110 and 112, the customer can dial the SAR alarm call (maritime distress call) in the coastal area of the North and Baltic Seas using the number 124 124. The SAR alarm call does not replace the usual maritime radio services.

#### 11.3. Conciliation procedure

Customers in a dispute with sipgate may initiate a conciliation procedure with the Federal Network Agency by submitting an application pursuant to Section 68 TKG.

The details of the conciliation procedure are regulated by the Federal Network Agency in a conciliation order, which it publishes.

EU Commission platform for online dispute resolution: [www.ec.europa.eu/consumers/odr](https://webgate.ec.europa.eu/odr/main/index.cfm?event=main.home.show\&lng=DE\&ampDeviceId=b06aff2e-fdc0-4bd9-9e23-ecaea52e6388\&ampSessionId=1767690360698)

#### 11.4. Inclusion in public subscriber directories

The customer may at any time request to be entered free of charge in a publicly accessible subscriber directory with their phone number, surname, first name and address, or to have their entry deleted or amended.

#### 11.5. Security or integrity of the telephony and data processing systems

In providing its services, sipgate places great importance on the security and integrity of its systems and data, as well as on the correct functioning of the systems used. sipgate's infrastructure is always kept up to date with the latest technology and complies with the respective current technical guidelines and valid standards. In the event of breaches or identified vulnerabilities, measures are taken immediately to prevent and avoid them in the future. This applies in particular both to potential attacks on sipgate's network and to the proposed and implemented protective measures. sipgate has a security concept that has been approved by the Federal Network Agency.

sipgate has implemented numerous technical and organizational measures in order to prevent security or integrity breaches as well as threats and vulnerabilities and to respond to them at an early stage.

Examples of such measures are:

* sipgate regularly checks the technical equipment used for possible security vulnerabilities in order to identify and remedy possible threats or vulnerabilities at an early stage.
* sipgate continuously monitors published security vulnerabilities.
* sipgate regularly monitors and maintains the technical equipment used and has automatic monitoring for the essential systems 24 hours a day, 365 days a year, and can therefore respond rapidly at any time to acute security or integrity breaches.
* sipgate operates its own Network Operation Center, which monitors, among other things, the main network platforms and systems.
* sipgate implements the current technical guidelines and standards aimed at implementing technical measures to ensure integrity, i.e. among other things, being able to identify corrupt data as such and, if necessary, retransmit the data.
* sipgate informs the affected customers of any breach of security or integrity.
* sipgate has implemented and integrated an emergency concept. If vulnerabilities are identified at sipgate in any form whatsoever, they are remedied immediately.

#### 11.6. Blocking certain number ranges

The national number ranges 0137, 0138, 01212, 0181, 0185, 0188, 0900 and 118xx are blocked. Individual blocking of specific national or international number ranges and specific special numbers is not possible.

#### 11.7. Withholding caller ID

The customer has the option of permanently or temporarily withholding the display of their phone number to the called party, if the function is supported by their end device.

#### 11.8. Blocking number ranges/services provided in addition to the connection

The customer has the option to block certain number ranges pursuant to Section 61(1) and a right to block the use and billing of services provided in addition to the connection via the mobile connection pursuant to Section 61(2) TKG.

#### 11.9. Use of the Call by Call and Preselection service of netzquadrat Gesellschaft für Telekommunikation mbH (01064) is possible. Other Call by Call and Preselection services are currently not available.

GET https://help.sipgate.de/ai-agents/en/privacy-policy-terms-and-conditions-and-dpa/sipgate-agbs.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
