Hi,
I am trying to integrate Google Pay with the Android app to get a token from Google Pay app and send it to our server, which in turn will pass it on to Authorize.net for processing. I was able to get the payment token by using the API key provided by Authorize.net and when I pass that to Authorize.net, I get error code 153 with the message "There was an error processing the payment data. Invalid ownership."

When signed up with Google, I received a MerchantID which I entered when enabling Google Pay in the Authorize.net account. There was a public key generated but I am not sure where and how to use that key. Has anyone run successfully integrated Google Pay with Authorize.net? Your help is highly appreciated.
