WebPAY PAYMENT FLOW

PAYMENT LEG

 

TRANSACTION STATUS CONFIRMATION LEG

 

Step 1

A HTTP POST request is made with certain transaction parameters to the Interswitch payment gateway service URL (https://sandbox.interswitchng.com/collections/w/pay). This is known as the beginning of the payment leg.

Step 2

A response is sent from the payment gateway. The response is sent to your site_redirect_url parameter specified in your POST request in Step 1 above. This ends the payment leg.

Step 3

The merchant’s website initiates a HTTP GET request to the payment gateway requesting the status of the concluded Payment transaction (i.e., Steps 1 & 2 above). This is the beginning of the getTransaction leg.

Step 4

A response is sent from the payment gateway containing the complete status of the transaction.
