Get Webhook for all customers who installed app.

Hi,

If I publish an app on the Zendesk marketplace, is there a way to listen to events for the customers' accounts who have installed the application via following OAuth flow?

I know we can set webhooks from the Admin panel but I don't want the users to do who install our application, instead automatically when the application is installed.

I talked to the support and they said to post a question here.
