Webhook Configuration

Hi team, We are trying to use the Adobe PDF services API. Is there any webhooks available in adobe for the pdf services api? We know that there is already webhooks availble for the adobe sign in api. And also the url we are requesting requires authentication. When we try to use the authentication in the url itself, we got an error like invalid url. Is there any other alternatives to use the authentication for the webhook url?  Thanks,  Naveen.
