Step 3: Implement desired callbacks.
For the list of available callbacks, please refer to Click-To-Pay Request object.
There are two main callbacks that must be implemented (the rest are optional):
onPaymentPrefill - calculates total amount and sets transaction information.
onPaymentSuccess - a callback that will be called after the consumer pays and Click-To-Pay returns a payload with all of the requested consumer information. This is where you need to make an ajax call to your server with the payload. The sample for making an ajax call is below:
