Need help with implementing payment flow

Webhooks and Events
1

I’m working on implementing a hybrid monthly payment flow that combines usage-based and fixed charges. Here are my key requirements:

I need to track when a user transitions from a free trail period to a paid plan. I can use the available webhooks for this.

Now, once they switch to a paid plan, I want to monitor when Shopify has generated their invoice and the amount charged for my app. So that I can show this to the merchant using the app.

Which webhooks / APIs can I use here?

Would querying the AppSubscription object get you this info?

Which graphql query can be used to query this object?

It would be the currentAppInstallation query.
