How to Receive Webhook from Stripe in Java

Here's what I did:

The Java method still takes in the Event as a json String. Then I used Stripe's custom gson adapter and got the Event with:

Event event = Event.gson.fromJson(stripeJsonEvent, Event.class);

Where stripeJsonEvent is the string of json taken in by the webhook endpoint.

I have been looking for the same answer, so after looking at their own code, here is how they actually do it:

String rawJson = IOUtils.toString(request.getInputStream());
Event event = APIResource.GSON.fromJson(rawJson, Event.class);

APIResource comes from their library (I am using 1.6.5)

public String stripeWebhookEndpoint(@RequestBody String json, HttpServletRequest request) {         
        String header = request.getHeader("Stripe-Signature");      
        String endpointSecret = "your stripe webhook secret";
        try {
            event = Webhook.constructEvent(json, header, endpointSecret);
            System.err.println(event);
        } catch (SignatureVerificationException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
         //
         enter code here
      return "";

}
