To enable Google Pay, contact your Point of Contact at Google.

Offerings

PayU supports three types of Google Pay transactions:

Tokenized Cards Flow

In the latest Google Pay app version, users can opt to save their cards to make payments. These tokenized cards can be used to pay on merchant apps whitelisted by Google only.
Within the merchant app, selecting Google Pay invokes the in-app bottom sheet shown below with the list of saved cards and UPI options. Users can select a saved card from the list and complete OTP authentication within the fragment itself.

Note

The OTP auto-read and submit handled by Google Pay Fragment

To enable the tokenized card flow, contact your Key Account Manager at PayU.

In-App UPI Flow

If the user wishes to proceed with UPI Payment, the VPA can be selected from the Google Pay fragment. The user will have to authorize the payment with UPI PIN in the Google Pay app.

If the Google Pay app version that is installed doesn’t support this experience on the device, payment will be made through Intent flow. In the Intent flow, the Google Pay app is opened in full screen.

Web Flow

If the user’s device does not have the Google Pay application installed, PayU shows the Web UI to enter the VPA. This triggers a collect request to the user’s Google Pay application where he would need to authorize the transaction.
