API Version 3

Status: under development

The specification for the APIv3 is written according to the OpenAPI 3.1 Specification.

The file in the repository is split up into many files. Some OAS (OpenAPI Specification) do not support that. You can retrieve the complete, singular file from any OpenProject server under /api/v3/spec.json or /api/v3/spec.yml. Additionally, there is a script that outputs the specification as a whole as well, either as json or yaml depending on the given format argument:

./script/api/spec --format yaml > openproject-oas.yml
