While working with RT’s REST 2.0 API, and trying to figure out how it works, I’ve written down my findings as an OpenAPI spec (3.1). It’s not complete or anything, but I decided to share it nonetheless, as it could be of use to others as well.
You can find the spec here: RT / Request Tracker OpenAPI · GitLab
Feedback and patches are welcome!
Here are some tools for leveraging the spec: https://openapi.tools/
