# Versioning All endpoints and examples are designated with a specific version. Versions vary per endpoint and are not global. The response shape of a certain endpoint is not guaranteed to be fixed over time. In particular, we might add new keys to responses without bumping a version endpoint, which will be noted in the changelog. To ensure the security and correctness of your application, make sure to only read the keys from the response that your application needs. Don't proxy entire responses to third-parties without validation. Old versions of each endpoint are supported for as long as possible. When we intend to deprecate, we will notify users in the changelog section. Endpoint versions follow the base URL and come before the endpoint. For example: ``` https://api.cal.com/v1/users ``` Using version `1` of the users endpoint. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://calcom.gitbook.io/docs/enterprise-features/api/versioning.md?ask= ``` The question should be specific, self-contained, and written in natural language. 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.
