If you receive this error when using Web Drop-in or Web Components, please check the following:
- In your paywithgoogle.configuration object, ensure that you are using your Company or Merchant Account Code as the value for the gatewayMerchantId.
- In the same object, if you are using a Drop-in or Components version later than V3.13.0, and you specify the merchantName, you also need to specify the merchantId and gatewayMerchantId.
- Ensure you’ve added your shop domain to the GooglePay API console.
