Payment Notification

post

https://{merchant_server}/api/notification

Notification from Praxis where merchant would receive the latest status of the transaction.

Note: You would be sending notification_url as part of Initiate payment payload and Praxis would send the latest status to this mentioned url.

Important Guidelines

Retries: If your API response contains "status": -1 or returns an unrecognized format, the notification will be automatically resent in approximately 5 minutes.

Amount Changes: Transaction and session amounts may change during processing. For more information, refer Understanding Amounts.

Timeouts: To receive additional notifications in the event of a timeout, please contact our support team to enable the "Notifications for delayed processing via Direct API" setting. (The timeout is a configurable value in seconds).

Signature Calculation: Fields with a null value should be skipped when building the signature.
