Werk #19889: REST API: Comment creation endpoints hidden from the interactive GUI

Component REST API

In the interactive REST API GUI (Swagger UI), the endpoints for creating host and service comments did not show the comment_type field, while the API documentation (ReDoc) showed it correctly. This is caused by a known bug in Swagger UI that cannot be worked around in Checkmk 2.5.0.

To avoid confusion, the following endpoints are no longer listed in the interactive GUI:

  • POST /domain-types/comment/collections/host
  • POST /domain-types/comment/collections/service

The endpoints themselves are unchanged and still work as before. You can find their full description in the API documentation (ReDoc).

Checkmk 3.0.0 is not affected by this issue.
