Errors / contact_not_found

Contact not found

HTTP 422invalid_requestcontact_not_found

No contact with that number on this account.

What to do

Create the contact first. Entering someone into an automation does not create them, because a typo would then silently start messaging a stranger.

What it looks like

{
  "error": {
    "type": "invalid_request",
    "code": "contact_not_found",
    "message": "…",
    "doc_url": "https://docs.textmast.com/errors/contact_not_found",
    "request_id": "req_01j8xk2p7n4qc3m9v0wz5bt6ay"
  }
}

Quote the request_id if you get in touch. It is on every response, including this one, and it turns a support email into a single log query rather than an archaeology exercise.
