Notifications ​

Important Notes ​

  1. Notification URLs can be provided to Onerway in two ways: during merchant registration or through the notifyUrl parameter in transaction requests.
  2. The notifyUrl parameter takes precedence over the registered URL. If neither is available, no notification will be sent.
  3. Payment results are determined by asynchronous notifications. Do not use the status field in synchronous responses to determine payment results!

Signature Verification Steps

  1. When receiving an asynchronous notification, first remove parameters marked as No in the Signature column of the Notification Parameters. See Parameters Excluded from Signature for a complete list.
  2. Sort the remaining non-empty parameters by key in ASCII order, concatenate their values into a string, and append your merchant secret key.
  3. Perform a sha256 hash on the resulting string.
  4. After successful verification, return only the transactionId value.

Note

  • Asynchronous notifications may include new parameters in the future, which by default will participate in signature verification
  • When verifying signatures, be sure to exclude parameters marked as No in the Signature column rather than relying on a hardcoded list of parameters marked as Yes, to prevent signature verification failures when new fields are added
