Only eligible pending standard inquiries accept responses. Hosted actions complete through their links. Your API key determines organisation and environment scope.

Send a nonblank message, downloadable documents, or both:

{
  "message": "Supporting evidence attached",
  "documents": ["https://files.example.com/supporting-evidence.pdf"]
}

Replace the example URL. Supported files are JPEG, PNG, and PDF; Graph stores copies. Use documents, not files. Whitespace is trimmed. Neither field is required individually, but both cannot be empty.

Submission and retries

201 saves the response, leaves the inquiry pending for review, and emits inquiry_request.answered with response_id. It does not approve verification or activate the account.

Only one response is accepted, even after soft deletion. Further submissions, including identical retries, return 409. There is no Idempotency-Key support. After an uncertain result, check response history before retrying; 409 alone does not confirm success.

data contains the response record, including Graph-owned document references. meta is null.
