Path parameters

objectstring
issue_idstring
The issue.

A patch written by Rustine (unified diff), when one was generated in the app.

Status	error.code	What happens
401	authentication_required	No key in the request. Pass it in the `Authorization: Bearer rst_…` header, never in the address.
401	invalid_api_key	The key or OAuth token is wrong, revoked or expired. Check it is copied in full, or create a new key.
402	api_plan_required	The workspace is on the Free plan. The API comes with Pro, or on a 14-day trial with Solo.
402	api_trial_ended	Solo's 14-day trial is over. Move to Pro: your keys work again at once.
403	scope_missing	The OAuth token lacks the permission this route needs (shown on its page). Reconnect the agent to grant it. An API key has every permission.
404	resource_not_found	Nothing with this id in the key's workspace. An object of another workspace answers the same: its existence is never revealed.
404	fix_locked	The fix of this issue is not unlocked yet: `POST /issues/{issue_id}/fix` unlocks it.
429	rate_limited	Too many requests for this key (120 per minute). Wait `Retry-After` seconds.
500	internal_error	An error on our side, reported automatically. Retry later; give the `Request-Id` to support if it comes back.
503	service_unavailable	Rustine is unavailable for a moment. Retry with the same `Idempotency-Key`.
