}Customer can complete the payment by either scanning the barcode with their banking app or manually transferring the funds using the payment details — both the barcode and payment information are available on the page at challenge.challenge_redirect.url.
Rumbapay sends a callback to the merchant's callback URL when the payment reaches a terminal state (success, error, etc.)

}Callback
On every completed Payout we send a callback notification to the URL you passed in the request in the callback_url field.
We strongly recommend validating the callback signature to avoid suspicious activity. Follow the signature docs to prepare callback verification.
Callback flow
The callback flow follows these steps:
Rumbapay processes the payment request
When the payment status changes to a terminal state, Rumbapay sends an HTTP POST request to your callback URL
Your server should process the callback, validate the signature, and update your system
Your server should respond with HTTP 200 OK to acknowledge receipt
