• Manual Integration

To integrate Google Pay manually, follow Google's instructions and in the handlePaymentSuccess method, send the final token to our servers through some form of middleware to compute the hash using your passphrase.

We advise the use of our PHP Sample File as an example on how to build your own middleware, as it will forward requests to our servers and attempt to automatically compute a hash as well as determine the correct endpoint for the request.

The Google Pay token should be sent using the Digital Wallet processCard method.
