Sandbox Paypal webhook integration

Question

I am trying to integrate paypal webhook with my application. I have created an app in which I have configured webhook (entered the url and selected events) after that I am using webhook simulator to raise an event. I am using spring boot rest api in backend to receive webhook call. The API is of POST method type and just logging that i have received a call.

But api call is not triggrered.

Also I have checked for Webhook Events, No events has been generated till now.

For reference,

Please help !!

PS I am using sandbox for testing

If anyone facing same problem, please do check your listener server is having sha-2 compatible certs.

This is due to sha-2 compatible certs. Paypal requires the listener to be sha-2 compatible.
