The BetLink backend will send this API key to the operator endpoints in a header named '**X-API-Key'.** * We strongly recommend that access to the API is locked down and that BetLink's IP ranges are added to a per environment allow-list. * All exposed endpoints which will handle IMGA communication should support TLS v1.2 or higher. * User IDs sent to BetLink by the operator should be encrypted in such a way that they are not possible to decrypt for the BetLink platform (i.e. using a key unknown to BetLink). They should always be encrypted in the same way (so that the same user id will always generate the same encryption result) and the operator should be able to easily decrypt them to reveal the original user ID. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.sportradar.com/betlink-integration/backend-integration/security.md?ask=&goal= ``` `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.
