Handling Ozow Responses

Handling Ozow responses is crucial for merchants to update their backend systems properly. There are two types of responses you'll need to manage:

Types of Responses

Redirect Response
Notification Response

For more information, you can visit Ozow Documentation.

Hash Validation

It's important to validate the received responses to confirm their authenticity. You can do this by generating a hash on your end and comparing it with the one sent by Ozow.

Hash String Order

The order in which you concatenate the variables to generate the hash string is crucial. Below is a PHP example showing how to generate this hash string based on the variables you've provided:

$hashStr = $siteCode . "ZA" . "ZAR" . $amount . $transactionId . $bank_reference . $customer . $optional1 . $optional2 . $optional3 . $optional4 . $optional5 . $notifyUrl . $successUrl . $errorUrl . $cancelUrl . $isTest . $privateKey;

Note: Omit any variables that you did not provide on the FlutterOzowWeb widget.

By following these steps, you'll be able to effectively handle and validate Ozow responses in your merchant system.
