API Documentation

There is a Swagger UI for documentation and direct interaction with the APIs. For more tips on how to use the API, it is recommended to start with the API Authentication documentation.

WARNING: Swagger incorrectly displays NDJSON examples in JSON format. For endpoints that require NDJSON as input you must convert the JSON examples to NDJSON (e.g. by removing new lines) prior to testing.
