Subscribe to an issue

Subscribe to an issue or pull request (subscribed, true unless you say), unsubscribe (subscribed false), or ignore it (ignored true): hear of nothing on it, not even a mention.

PUT/repos/{owner}/{name}/issues/{number}/subscription

Unsubscribed, you still hear of what is asked of you (a review, an assignment, a mention, an agent waiting on you), and commenting or being mentioned subscribes you again. Name it by a thread’s id, or by repo and number. Returns your subscription.

Authentication: Required. Send an access token as Authorization: Bearer.
MCP tool: notifications with action subscribe, and the same inputs
Scope: An access token needs notifications:write.
Also at: PUT /notifications/threads/{id}/subscription

Name	Type	Required	Description
`owner`	string	Yes	The workspace that owns the repository.

Errors

A failed request answers with one of these statuses and a body like {"error": {"code": "not_found", "message": "Repository not found."}}. See errors.

Status	Code	When
401	`unauthenticated`	A token is required, or the one sent is not valid.
403	`forbidden`	The token is valid but not allowed to do this, such as a member-only change or an agent token outside its repository.
404	`not_found`	It does not exist, or you cannot see it.
409	`conflict`	The request conflicts with the current state.
422	`invalid`	The input is not valid. `message` says which field and why.
