Once you create a charge, a customer has to approve it, at which point they’ll be redirected back to your app with a charge_id parameter. From there, you can activate the approved charge to commence the billing cycle.
Once you activate the charge, the recurring application charge ‘status’ becomes ‘active’. If you see the charge is active, you can keep a record on your side to know they’re paying.
If a customer uninstalls you app, the charges are automatically stopped.
Once the merchant approves the subscription, the subscription status will automatically change from “pending” to “active” (no more “accepted” in between).
