Terminals
Create a terminal payment
OAuth scope: terminal.write
Initiates an async payment on a specific terminal. The terminal must be powered on and connected to the internet.
The response is 202 Accepted — the payment has been queued but not yet processed.
Precondition: The terminal must be powered on and connected to the internet. If offline, the request is accepted but no payment will be processed. Implement a client-side timeout (~120 seconds) to handle this case.
Idempotency: The X-Qonto-Idempotency-Key header is required. Use it to safely retry requests without creating duplicate payments.
Metadata: The optional metadata field lets you attach free-form context to the payment. It must be a valid JSON object and must not exceed 1kB. It is stored as-is and echoed back in the 202 response. Use it to cross-reference the payment with your own system — for example, an order ID, table number, or any other POS-specific data. The content is not interpreted by Qonto.
