If I implement Oauth with salesforce in my custom app, I understand that I am now able to make API requests to their salesforce data on the user's behalf by using the access token given to me. But, I am also trying to set it up so that once the user Oauths with salesforce through my app, salesforce is automatically able to send updates to my API. Does anybody know how to do this? I've so far found a lot of tutorials on how to manually set up a single webhook by logging into salesforce with my account, and then provide the URL of my API that salesforce can post updates to, but how do I set this up to automatically happen so that I don't have to manually go in and provide the API URL to salesforce for each customer? Thanks
