Technical flow – Prepaid Payments

1. The user selects a product, confirms the booking and clicks on PAY in the Switch App .
2. Switch server hits the PhonePe server sending order details like merchantId, transactionId, OrderId, transactionContext, cartDetails and redirectionURL as described in the PhonePe initiate Transaction Request() API

transactionContext takes trackingInfo as input which is used on the PhonePe APP to take a user to their specific booking inside the Switch App. Example :

"trackingInfo": {
        "type": "HTTPS",
        "url": "https://google.com"
      },

For eg.,
In the image below, a ​user can click on “View Details” to get redirected to the Food Switch App on PhonePe and list the booking details corresponding to the transaction Id. You can find the details here.

Switch need to share its cart details with PhonePe in initiate API. You can find the details for your use-case here

"cartDetails": {}

3. PhonePe’s server sends back the response of initiateTransaction API () API to the Switch server which needs to be passed onto the Switch.
   Example:
   In response to initiateTransaction API() API, Switch server would receive “redirectionURL” field which needs to be opened on the Switch merchant application
