### 1. Formation and termination of the contract

#### 1.1. Formation of the contract

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

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

#### 1.2. Ordinary termination

1.2.1. The details regarding the notice period are governed primarily by the service description sipgate. Unless otherwise stipulated 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 cannot reasonably be expected of sipgate to wait until the notice period expires. 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 number assigned to them 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 debits have been made.

1.3.2. sipgate also has the right to extraordinary termination in the event of a change in the statutory basis of this contract, orders and/or directives relating to the contract issued by authorities, courts or other holders of public authority, provided that this results in it becoming 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 credit 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. sipgate will make the reimbursement by means of a credit to the bank or credit card account specified by the customer.

1.4.2. Any other form of 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 duties to cooperate

2.1. It is the customer's responsibility to maintain internet access suitable for use with sipgate (see prerequisites for use – internet access). If this is not the case, the mutual obligations to perform under the contractual relationship remain unaffected.

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

2.3. sipgate processes essential communication processes (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 without delay of any changes to their email address.

2.4. If any changes arise that affect the flow of communication or the contractual relationship between the customer and sipgate, sipgate must be informed without delay. This reporting obligation applies in particular to the following points:

* Change of the customer's place of residence/registered office (among other things necessary for the correct location of emergency calls). Further information at: [Instructions for making emergency calls](http://www.sipgate.de/team/nutzungsbedingungen#emergency_call)
* Change of the customer's email address
* for payments using the Autoprepay procedure, the bank details and credit card information.

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

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 to 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 shared access data with third parties (e.g. their employees), they must inform them of the obligation to keep the access data confidential and secure and bind 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 number may be transferred, if necessary, 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 is not affected thereby.

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

* if the customer agrees to the change,
* if this is required due to legal regulations 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 cannot be resolved by sipgate otherwise with reasonable effort.

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

2.11. If there is misuse by the customer or a user authorized by them (e.g. violations of 2.5, 2.6, 2.10 or comparable breaches) and the customer does not stop the misuse within a reasonable period despite a request from sipgate, 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 the event of abusive use, unless the customer proves that they are not at fault for a breach of duty.

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

3.4. The charges for the VoIP service are based on the price list valid at the start of each individual connection for the product selected by the customer as set out in the service description sipgate. The current price list can be viewed online at any time via the currently valid 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: In this procedure, the customer first pays an amount of their choice to sipgate (sipgate credit) and can only use chargeable sipgate products after payment has been received, in line 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 sipgate has provided the service, on the basis of a corresponding 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 arise as a result of telephone calls or monthly charges. 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 for this. Participation in the Autoprepay method is, however, only possible if the customer gives their consent to recurring direct debit or credit card payments. The customer must declare their consent when activating the Autoprepay billing procedure in their account or in writing or by email to sipgate. If the selected payment method is not successfully charged, sipgate is entitled to use alternative payment methods stored in the account.

4.2.2. The pre-notification period (Pre-Notification) 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 them. sipgate will charge the customer for the costs incurred in connection with the rejection (third-party charges of the customer's bank and the bank charges of sipgate) and debit them from the account balance, unless the customer proves that no damage at all or damage of substantially lesser extent has been incurred.

4.2.4. If, in an exceptional case, the customer pays in another way, for example in the event of late payment due to a returned direct debit or insufficient funds in the account, discharge shall only occur if the customer has provided sufficient payment reference details (in particular the invoice number or a comparable, unique booking code from sipgate) with the payment. This applies accordingly to payments made 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 a PDF file by email or for download. It is not possible to receive an invoice in paper form.

4.3.2. The customer agrees to have their invoice sent 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 (§ 14 para. 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 other regular intervals) are due on the 1st day of each month (or period), unless otherwise regulated in the service description. Where claims do not arise at regular intervals, they 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 § 61 para. 3 et seq. TKG.

4.4.4. If the customer is a consumer (within the meaning of § 13 BGB) and is in default, interest at five percentage points above the respective base rate of the European Central Bank shall be charged. If the customer is an entrepreneur (within the meaning of § 14 BGB), interest at eight percentage points above the base rate shall 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 taken into account. This also applies 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 are stored in full.

4.4.6. The customer may only offset claims by sipgate GmbH against claims that have been finally established by a court 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 that sipgate offsets against basic fees and telephone 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 arose. The amount of the offsetting can be seen in the itemized connection record.

The due date of the invoiced amount is not affected by the raising of objections.

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 were raised.

4.5.3. If objections are not raised within the eight-week period under No. 4.5.1, the invoice/offsetting against credit is deemed to have been approved by the customer. sipgate points out this legal consequence in the invoices.

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

### 5. Data protection

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

5.2. Data processing is therefore permissible in particular insofar as this is necessary. This is necessary for the establishment and design of the contractual relationship (inventory data), for the provision of telecommunications services (connection data), and for billing thereof (billing data).

5.3. sipgate observes telecommunications secrecy in accordance with 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 T\&Cs.

5.5. The customer commissions sipgate to maintain a monthly itemized connection record, which the customer 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 numbers of the connections are either shortened by 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, the full listing is 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, immediately and to comply with the co-determination regulations.

5.6. The customer commissions sipgate to store the key data (time, duration) of telephone calls, faxes and SMS sent to or from 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 gives a corresponding instruction, but only insofar as this is permitted under the TKG or other legal norms. If objections have been raised, sipgate is entitled to retain the traffic data until the objections have been finally clarified.

### 6. Liability

6.1. For property damage, sipgate's liability is limited to a maximum amount of €12,500.00 per customer. In relation to all customers combined, liability is limited to €30 million per single act or single damaging event. If the amounts payable to several customers on the basis of the same event exceed the maximum limit, compensation shall be reduced in the ratio in which the total of all claims for damages bears to the maximum limit. The limitation of liability does not apply if the damage was caused intentionally.

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

6.3. Otherwise, sipgate is liable only for gross negligence or intent, unless the matter concerns the breach of an essential contractual obligation (so-called cardinal obligation). In the case of a slightly negligent breach of a cardinal obligation, liability is limited in amount to such contract-typical 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 foregoing 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, corporate bodies, representatives and vicarious agents.

6.6. sipgate's obligation to perform applies only if sipgate itself has been supplied in accordance with the contract and on time with corresponding advance services and has not breached any duties of care in this respect. In the event of disruptions to performance due to force majeure, sipgate is in any case released from its obligation to perform.

### 7. Liability in 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 cannot therefore be ruled out, even if the AI system operates within its specific parameters.

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 omissions of notices arising from the AI in customer contact.

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

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

7.5. The customer shall indemnify sipgate against all third-party claims asserted in connection with the use of the AI applications vis-à-vis end customers, unless these are based on a breach by sipgate of statutory or contractual obligations.

### 8. Changes to charges, the General Terms and Conditions (T\&Cs) and the service description

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

* in the event of changes to the rate of VAT, sipgate is entitled to adjust the charges accordingly to reflect the change,
* if the Federal Network Agency or another authority explicitly requires an increase in charges, sipgate may amend the charges accordingly, and
* if third parties from whom sipgate obtains necessary upstream services for the performance of the services owed under this contract increase their prices, sipgate may pass on this price increase to the customer.

A prerequisite for an increase in charges by sipgate is that sipgate informs the customer of the change in charges 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 § 13 BGB), the customer has an extraordinary right of termination in the event of an increase in net charges, which takes effect at the time of the relevant change in charges. If the customer does not exercise this right of termination within four weeks of receipt of the notice of the increase in charges, the change is deemed approved. sipgate expressly points this out again in the notice of the increase in charges.

In the event of changes to VAT, sipgate is entitled to adjust the charges accordingly without this giving rise to a right of termination for the customer.

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

8.4. sipgate is entitled to amend these T\&Cs 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 non-consideration of which would noticeably disturb the balance of the contractual relationship. Essential provisions are in particular those concerning the nature and scope of the contractually agreed services and the term, including the provisions on termination.

Furthermore, amendments or additions to the T\&Cs may be made insofar as this is necessary to remedy difficulties in the performance of the contract due to gaps in the rules 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 T\&Cs are affected. If the change results in a deterioration for the customer, a change is permissible only on the condition that sipgate informs the customer of this by email no later than 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 the amendment 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 performance of its services change their range of services. If the change results in a deterioration for the customer, a change is permissible only on the condition that sipgate informs the customer of this by email no later than six calendar weeks before it takes effect.

8.6. Intended changes to the T\&Cs and the service description pursuant to clauses 8.5 and 8.6 are notified to the customer by email at least six weeks before they take effect. If the change to the T\&Cs or the service description is disadvantageous to 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 become part of the contract at the time they take effect. The customer is 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, to contact customer support in writing via the contact form or by telephone, and, for example, to report faults.

### 10. Final provisions

10.1. The customer's deviating General Terms and Conditions do not apply, even if sipgate does not expressly object to them.

10.2. Free additional services provided by sipgate do not form 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 transfer the rights and obligations under this contract to a third party only with sipgate's prior written consent.

10.4. The use of products and services of sipgate GmbH in 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 sipgate's service is not permitted.

10.6. Only the law of the Federal Republic of Germany shall apply between the customer and sipgate, as it applies between domestic persons to the exclusion of the UN Convention on Contracts for the International Sale of Goods, unless mandatory law prescribes the application 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 transfer the customer's inventory data to third parties insofar as this is necessary for the purpose of assignment or collection of claims. Statutorily permitted transfer 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 verified using a suitable procedure.

### 11. Customer information under the TKG

#### 11.1. Emergency call (landline)

The emergency numbers 110 and 112 can be reached via sipgate. These are activated for your stored address. The customer must check at regular intervals 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 made can proper emergency-call functionality, in particular the reachability of the nearest fire brigade or police station, be guaranteed. If you use sipgate from a location other than the stored address (nomadic use), emergency service provision may not be possible at all or only if you can inform the emergency center of 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 applicable in Germany can only be placed with a valid SIM card inserted. Different rules may apply outside Germany. In the event of an emergency call to 112 and 110, location information about the caller may also be transmitted to the responsible emergency call answering point. In addition to the general emergency numbers 110 and 112, the customer can call the SAR alarm number (maritime distress call) on 124 124 in the coastal areas of the North Sea and Baltic Sea. The SAR alarm number does not replace the usual marine radio services.

#### 11.3. Conciliation procedure

If customers are in dispute with sipgate, they may initiate a conciliation procedure at the Federal Network Agency by submitting an application pursuant to § 68 TKG.

The Federal Network Agency regulates the details of the conciliation procedure 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 directories

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

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

In providing its services, sipgate places great emphasis on the security and integrity of its systems and data and on the correct functioning of the systems used. sipgate's infrastructure is always kept up to date with the state of the art and complies with the current technical guidelines and applicable standards. In the event of infringements or identified vulnerabilities, measures are taken immediately to prevent them and avoid them in future. This applies in particular both to potential attacks on sipgate's network and to the protective measures proposed and implemented. 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 be able 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 be able 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 around the clock, 365 days a year, and can therefore respond quickly at any time to acute security or integrity breaches.
* sipgate operates its own Network Operation Center, which monitors, among other things, the essential network platforms and systems.
* sipgate implements the current technical guidelines and standards aimed at implementing technical measures to ensure integrity, i.e. to be able, among other things, to identify corrupt data as such and, if necessary, to carry out a retransmission of 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 number blocks, as well as specific premium-rate numbers, is not possible.

#### 11.7. Suppression of caller ID

The customer has the option of permanently or temporarily suppressing the display of their number to the called party, provided that the function is supported by their terminal device.

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

The customer has the option of blocking certain number ranges under § 61 paragraph 1 and a right to block the use and billing of services provided in addition to the connection via the mobile connection under § 61 paragraph 2 TKG.

#### 11.9. The 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.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

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

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
