allowed_recipient_not_found

No such entry. Answered with 404.

What it means

The Org has no Allowed Recipient entry with that id. An entry granted automatically by verified inbound mail expires on its own, so an id read a while ago may be gone.

What to do

List the entries with GET /api/allowed-recipients or GET /api/identities/{handle}/allowed-recipients and use an id from there.

The body

{
  "type": "https://tigby.eu/problems/allowed_recipient_not_found",
  "title": "No such entry",
  "status": 404,
  "detail": "…what was refused, naming this request's own values",
  "code": "allowed_recipient_not_found",
  "doc_url": "https://docs.tigby.eu/errors/allowed_recipient_not_found",
  "agent_hint": "…the next step, for software"
}

Branch on code. The detail names this request's own Handle, id or limit and is not part of the contract.
