Response - 200 OK

1. First, you should check error_code field of response.

   If error_code field is not equals to 0 - transaction is Failed.

2. Second, you should check status field.

   The status field will always be set to created if there are no errors.

   Make check request or wait for a callback to get final transaction status.

Challenge type: redirect

}

If the challenge.challenge_type is set to redirect, you must send your Customer to the URL specified in challenge.challenge_redirect.url.

---

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.)

Response - 400 Bad request

    "error_code": 30,

    ],
    "timestamp": "2025-04-11T16:58:57.11Z"
}

If incorrect values are provided for widget.method or currency, you may receive the following response:

{
    "error_code": 273,
    "error_message": "Invalid adapter route configuration"
}

---

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:

1. Rumbapay processes the payment request

2. When the payment status changes to a terminal state, Rumbapay sends an HTTP POST request to your callback URL

3. Your server should process the callback, validate the signature, and update your system

4. Your server should respond with HTTP 200 OK to acknowledge receipt
