I've put in the credentials that I got from Google Wallet Merchant, but I'm assuming that it won't work without Zoho's gateway adapting to Google's new Wallet API. Can anyone help me in getting Google Wallet to work with Zoho Invoice?Google Checkout suggests the failure to accept payment was because the merchant credentials (Merchant ID and Merchant Key) were incorrect. Please ensure that you have entered the correct merchant credentials for Google Checkout in Zoho Invoice.
