This is the only public API available for gym owners to connect their BTWB data with external applications. BTWB does not offer any other external APIs at this time. The Zapier integration provides read-only access to your BTWB data and services. It does not access or integrate with any third-party systems outside of BTWB. ### What You Can Do With the Zapier integration, you can automate workflows such as: * Adding new clients to your email marketing platform * Sending Slack notifications when a client checks into class * Updating a spreadsheet when subscriptions change * Triggering custom webhooks for your own applications --- # 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 following URL with the `ask` and `goal` query parameters: ``` GET https://btwb.gitbook.io/btwb/developers/overview.md?ask=&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.
