Testing Google Pay

Testing Against a Real PSPs sandbox

You can test Google Pay^TM against a real Payment Service Provider (PSP) the same way as regular Google Pay payments. There are no additional merchant configuration changes required; and you can use the PaymentData JSON in the nonce field when making a payment.

See the Testing page for more information.

Testing Against a Mock Sandbox

You can use set values in our mock sandbox to test different responses. To get access to our mock sandbox, please get in contact with support.

After you are set up, you can send a payment, using POST /v1/payments, with the amount set to the below values to test the different responses. Google Pay is used as the payment instrument and Nuvei is the PSP - for other PSPs please get in contact with support for more information:
