User Experience for GooglePay

Key integration changes for integrating GooglePay via Hyper SDK

tep 1 - Order creation

CreateOrder on Juspay Servers.

Step 2 - Displaying Gpay option on payment page

The GPay in-app flow is allowed only when four conditions are satisfied:

Scenario 1: If the preference is to use only Gpay in-app flow, the merchant shall perform isDeviceReady call (refer code snippet on the right) for the current device and display GooglePay on UI only if it isDeviceReady response is true.
Scenario 2: If the preference is to use Gpay in-app flow along with UPI Intent as fallback option, then the merchant shall check whether GPay app is present on user device and accordingly display the GPay option. Pls use the List available UPI Apps call for this operation. The isDeviceReady call is not relevant for this scenario.

Step 3 - Initiate wallet transaction

Use walletTxn operation to initiate GooglePay. Please ensure that you pass below params, specifically for GooglePay in-app flow

paymentMethod :: GOOGLEPAY
sdkPresent :: ANDROID_GOOGLEPAY
allowedMethods :: ["UPI","CARD"] (Pass UPI or CARD or both the flows to whitelist the flows that must be allowed)
useFallback :: true/ false (if passed as true, user shall fallback to UPI intent flow, when GPay app version does not support in-app flow, default value will be true)
Note
Ensure that below Gpay configs are added at Juspay end-

Enable/ Disable fallback flow
Choose the fallback flow required (UPI Intent)
