You might encounter the following errors at some point in your integration. This list provides some helpful troubleshooting advice should these errors arise.

This merchant is not enabled for Google Pay

The Google Pay API can only be used on websites in a secure context. For more information, see Secure contexts.
No keys found for this merchant profile
You must register your public encryption key with Google via the Google Pay and Wallet Console to complete a DIRECTtokenizationSpecification type integration.

merchantId

You might encounter the following errors related to merchantId at some point in your integration. This list provides some helpful troubleshooting advice should these errors arise.

merchantId must be set!
The merchantId parameter inside PaymentDataRequest must be set to the value provided using the Google Pay and Wallet Console. A merchantId parameter is only required when you use a PaymentsClient configured for a PRODUCTION environment. Review our Integration checklist to request a review of your website's use of the Google Pay API and to obtain your merchantId.
merchantId is not a string
The merchantId parameter inside PaymentDataRequest must always be a string. Ensure that the type of the merchantId parameter you use is a string before you call the API.
merchantId is not registered.
The merchantId parameter inside PaymentDataRequest must be provisioned via the Google Pay and Wallet Console. Review Request production access for more information.

Gateway validity

You might encounter the following errors related to gateway validity at some point in your integration. This list provides some helpful troubleshooting advice should these errors arise.

Unknown gateway 'yourgateway'
The gateway parameter you specified in paymentMethodTokenizationParameters.parameters isn't currently supported by Google. Contact your gateway for more information on their gateway identifier and associated fields, such as gatewayMerchantId.
Gateway 'example' cannot be used in production mode
The example gateway parameter value is only used for testing purposes and can't be used with a PaymentsClient configured for a PRODUCTION environment. Contact your gateway for more information about the PaymentMethodTokenizationSpecification parameters values that you need to set for use with the Google Pay API.

Object validity

You might encounter the following errors related to object validity at some point in your integration. This list provides some helpful troubleshooting advice should these errors arise.

Google Pay's PaymentDataRequest is not valid json
The parameter provided to loadPaymentData must always be a valid PaymentDataRequest object.
transactionInfo must be set!
The transactionInfo parameter inside PaymentDataRequest must always be a valid TransactionInfo object.

Direct merchants

You might encounter the following errors related to direct merchants at some point in your integration. This list provides some helpful troubleshooting advice should these errors arise.

Signature verification
You might encounter a signature verification error if the merchantId is wrong. This can happen in the TEST environment when you use the Tink library. To avoid this issue, set YOUR_MERCHANT_ID to 12345678901234567890 in:
.recipientId("merchant:YOUR_MERCHANT_ID")
Cannot decrypt token
If you use the Tink library to decrypt a token, take note of the following:
  • Ensure that the Google Pay API response environment corresponds with the Tink environment. For more details, see the following example:
    • If the Google Pay API response was returned by the environment TEST, then Tink points to the test environment for decryption.
  • Don't modify the response from Google Pay API before it's passed to Tink. Ensure that you pass the entire token returned from the Google Pay API response. For more details, see the following note:
  • Verify that you have the proper private key associated with the public key that you registered with Google.
Generate public and private key pair on Windows
If you're on Windows, and you want to follow the steps mentioned in Use OpenSSL to generate a private and public key pair, make sure you install Cygwin on your machine. This is needed to run the Linux commands.

Error objects

CardInfo

What is the CardInfo feature?
Google Pay indicates to consumers that there’s a card behind the Google Pay payment button, which renders both the card brand network and the last four digits of the card.
Why doesn't the CardInfo feature render in my implementation?

To make the CardInfo feature work, we require the following conditions:

Why does the Google Pay payment button load indefinitely?
Don't remove the onLoad event listeners. If you remove the onLoad event listeners, it can cause the Google Pay payment button to load indefinitely.
Why is there no payment prompt after I click the Google Pay payment button?
Assign an event listener callback to the ButtonOptions.onClick event.
