Update a project release comment

PATCH/api/v2/workspaces/{slug}/projects/{project_id}/releases/{release_id}/comments/{pk}/

Change a comment's body, mark it resolved or unresolved, or move it under another parent comment.

PATCH is partial. Send only the fields you want to change. Changing comment_html sets edited_at to the current time. Changing only is_resolved or parent_id leaves edited_at as it was.

Updating needs edit access to the release, and returns 403 without it. The API doesn't check who wrote the comment, so anyone who can edit the release can update any of its comments.

Path Parameters

slug:requiredstring

The workspace slug. It appears in your Plane URLs. In https://app.plane.so/my-team/projects/, the slug is my-team.

project_id:requiredstring

The project the release belongs to. Accepts the project UUID or its bare identifier, for example ENG.

release_id:requiredstring (uuid)

The release the comment is on.

pk:requiredstring (uuid)

The id of the comment to update.

Body Parameters

comment_html:optionalstring

The new comment body as HTML. Replaces the stored body and sets edited_at.

is_resolved:optionalboolean

Mark the comment resolved (true) or reopen it (false).

parent_id:optionalstring (uuid)

The comment this one replies to. Send null to make it a top-level comment.

Response shaping

fields:optionalstring

Comma-separated list of fields to return. Unrequested keys are omitted from the response, not returned as null, so absent means "not requested" and null means "actually null". id always comes back whether or not you name it.

Pass all for every requestable field. An unknown name is a 400 that lists the valid set and suggests the closest match, so a typo can't silently cost you the saving.

Requestable here: comment_html, comment_id, created_at, created_by_id, edited_at, id, is_hidden, is_resolved, parent_id, release_id, updated_at, updated_by_id.

See Sparse fields.

Scopes

releases.comments:write

Errors

Status	Code	Cause
400	invalid_request	A body field has the wrong type, for example a parent_id that isn't a UUID.
401	unauthorized	Missing or invalid credentials.
402	payment_required	Project releases aren't enabled on your plan.
403	forbidden	Your role in the project can't edit this release, or your token scope doesn't allow this.
404	not_found	No such comment on this release, or no such release in this project.
406	not_acceptable	The Accept header asks for a representation the API can't produce.
409	conflict	Not raised by this endpoint. The spec lists it for every v2 write.
413	payload_too_large	The request body is over the size limit.
415	unsupported_media_type	The Content-Type isn't one this endpoint accepts.
429	rate_limited	Throttled. Honor the Retry-After header before retrying.
