Problem : At the time of Stripe Webhook URL integration with my grails application, I was getting an empty request in webhook URL and it confused me a lot. Finally i found out that Stripe sends response back to webhook URL in JSON format. I was not able to print the response received with params or request object.
Solution:params and request do not show the JSON request data. You can see the JSON request data through request.JSON, even params.JSON will not work.
