Delete an Origin Pull Request Comment via the API

Remove a pull request comment by its Origin id with DELETE https://api.cursor.com/v1/origin/repos/{ownerSlug}/{repoName}/pulls/comments/{commentId}. Official reference: Origin API → Delete Pull Request Comment (OpenAPI OriginService_DeletePullRequestComment). Changelog: September 22, 2026.

Origin is in Early Beta and subject to change. Authenticate with an installation access token (oit_…) or a user access token that carries repository:pull_requests:reviews:write. Availability: Early Beta per the API overview.

The comment's author can always delete it. Any other caller must also hold write access to the repository through repository:contents:write, or the call returns PermissionDenied (HTTP 403). Deleting the last comment of a thread removes the thread. Deleting any other comment leaves the thread in place. The comment's reactions and edit history go with it. An unknown or already-deleted id returns 404.

Cost: 5 points against the principal budget (ordinary write).

Pitfalls

• A 404 never confirms the comment is gone versus unreachable to this credential.
• Non-authors need repository:contents:write in addition to reviews write, or they get 403.
