I configured a webhook using Revenucat and linked it to my Laravel backend. When I tested it with Revenucat's "send test with webhook" option, the request was sent to the backend and returned a 200 status code. However, when I tried it with our application on the Play Store, the webhook didn't work, and the request wasn't sent to the backend. I'm developing the mobile app using Flutter. What could be causing this issue? how can playstore know the correct webhook.?
