Google Pay Drop-in integration

On this page, you can find additional configuration for adding Google Pay to your Drop-in integration.

When shoppers select Google Pay, Drop-in presents the Google Pay payment sheet where shoppers choose a card they want to use. If shoppers select a card that requires 3D Secure authentication, Drop-in also handles redirecting shoppers to another website to complete the verification.

Before you begin

Before starting your Google Pay integration:

1. Make sure you've integrated Drop-in v4.0.0 or later.
2. Contact our Support Team to add Google Pay in your test Customer Area.

To accept live Google Pay payments, you must complete all of the steps in Before you go live.
