Thanks for posting! You could set up connections to different payment gateways using our API Connector, which lets you connect to any service that exposes a JSON-based, RESTful web API. You can use this to add API calls to fetch data from an external service, or post data to trigger some actions on the service’s end.

You might also consider the plugin discussed here which allows you to accept Google Pay in your application!
