Method: transactionInitiatedNotification

This API is used by Google to notify the integrator that a payment transaction has been initiated within the Google system. The integrator will inform Google of the transaction's final result by calling the CaptureResultNotification API.

The requestId within the header is the idempotency key and uniquely identifies this transaction.

If the endpoint encounters an error while processing the request, the response body from this endpoint should be of type ErrorResponse.
