webhooks payload is not delivery to my laravel app from flutterwave, flutterwave complain about webhook url, #laravel #spatie webhook-client

Question

on my laravel application i use laravel spatie webhook-client to make receive webhook request from payment gateway(flutterwave to be precise). the webhook route is Route::webhooks('/flutterwave/call'); and the webhook url is https://my_url.com/api/flutterwave/call which i already added to my flutterwave test account and also configured the necessary signature.

i make an api call to the url (https://my_url.com/api/flutterwave/call) on postman it work perfectly. the issue is flutterwave keeps complaining about my url screenshot of flutterwave response after trying to make payment on the app

i want to get flutterwave webhook payload so as to settle transaction on my app
