Inbox comments

Reply to comment

Post a reply to a post or specific comment. Requires accountId in request body.

Idempotency: send an Idempotency-Key header to make retries safe (e.g. after a client-side timeout where delivery is unknown): same key + same body replays the original response (with Idempotent-Replayed: true) instead of posting the comment a second time; same key + different body returns 422; a key still in flight returns 409. Keys are retained for 24 hours and are scoped to the credential and to this exact path, so reusing a key against a different postId returns 422 rather than replaying the other post's response.

Only successful (2xx) responses are stored for replay. If the request throws or returns a non-2xx status the key is released, so the header protects the "request succeeded but the response was lost" case. After an ambiguous failure (a 5xx or a network timeout) list the post's comments before retrying with the same key, and treat an empty result as inconclusive rather than as proof nothing was posted.
