Discussions API

Discussions are a set of related notes on:

  • Snippets
  • Issues
  • Epics
  • Merge requests
  • Commits

This includes system notes, which are notes about changes to the object (for example, when a milestone changes, there will be a corresponding system note). Label notes are not part of this API, but recorded as separate events in resource label events.

Discussions pagination

By default, GET requests return 20 results at a time because the API results are paginated.
