This endpoint allows you to check the status of a previously initiated transfer. You must provide the payment ID (retrieved during transfer initiation POST /api/v1/payins via the id parameter) in the request.

The response includes the transfer’s current status as well as details such as the id, amount, currency and reference.

Response example

{
                      "id": "8f4c2f3a-9b76-4c39-9e6e-2d7c4dcb1e92",
                      "status": "Done",
                      "currency": "EUR",
                      "amount": 100,
                      "reference": "REF-20251121-1001"
                    }

Only Done and Failed are considered final statuses.

🚧
Both API key and token-based authentication methods are currently supported. Token-based authentication is strongly recommended for higher security and future compatibility, as API key-only authentication will be decommissioned by the end of March 2026.
To authenticate:

When using an API key, include it in the request as an x-api-key header.

When using a token, include it as an Authorization header in the format:

Authorization: Bearer YOUR_TOKEN
