11.2 Step 2: Send Queued Transaction
When you load the payment page and present the Google Pay button, you will send to the page the paywayRequestToken that was returned in step 1. No other data should be sent to the page. When the user clicks the Google Pay button, an interaction with the Google Pay payment sheet happens. When the user approves the payment, a sendQueuedTransaction request is sent by the JavaScript to Payway and the transaction is processed. Only the resultCode and paywayMessage are returned to the web page.
