Some countries and payment types need a document with the payment. Upload it first, then put its ID on the order.

curl -X POST 'https://sandbox-api.transfi.com/v3/invoice' \
  -H 'Authorization: Basic YOUR_BASE64_CREDENTIALS' \
  -H 'mid: YOUR_MID' \
  -F '[email protected]'

{ "status": "success", "data": { "invoiceId": "INV-250930081522714" } }

Then add "invoiceId": "INV-..." at the top level of the order — not inside source or destination.

→ Upload Invoice

⚠️
Attach it when you create the order. Adding it later means the order waits in review until you do.
