IT-Tremmel GmbH — API Documentation

Interactive documentation for all backend API endpoints. Select a spec from the dropdown to browse endpoints, parameters, request/response schemas, and try out requests.

Public access: Reading the OpenAPI docs does not require an API key, session, or JWT. Use /api/docs, /api/docs/openapi.json, and /api/docs/specs directly from your browser, CLI, or CI tooling.

Authentication: Most endpoints require either Authorization: Basic {base64} or X-API-Key: {key} header. Use the Authorize button above the endpoint list to set credentials for try-it-out requests.
