  title: Cal ID API
  description: >-
    API documentation for external developers integrating with Cal ID. This
    documentation is auto-generated from our OpenAPI specification and includes
    details on all available endpoints, request/response schemas, and
    authentication methods.


    Authentication is required for all endpoints and can be done using API key
    generated from the Cal ID dashboard under the `settings/developer/api-keys`
    page. Use the Authorization header with the Bearer scheme to authenticate
    your requests.


    Example:

    - API Key: `Authorization: Bearer calid_xxxxx`


    Note: To manage Team's resources use the Team's owner/admin API key
