Hi there,
I am currently working with Managed App Pricing system for monthly billing on my app, and I cannot find information about a Webhook that is triggered when the user completes a monthly payment.
I want to know if the APP_SUBSCRIPTIONS_UPDATE webhook is triggered after each monthly payment (after each month of use) or if I need to consider another solution, like setting up a cron job at the end of the billing cycle.
Thanks in advance for any guidance!
The app subscription update webhook is fired when the user picks a subscription, changes their subscription, the subscription expires or is not paid or the store closes.
It will not fire every month when a payment is successfully made. The user doesn’t pay each month it’s charged directly from their card.
Thanks for the answer !
I need to update my database after every month of usage, and currently, the only solution I can think of is to automate these updates every 30 days. I’ll handle cases when the user changes or cancels their subscription using the APP_SUBSCRIPTIONS_UPDATE webhook.
Do you know if there’s a better approach for this?
Any advice would be greatly appreciated
So you are updating your database just if the shop is still using the app? 
How does shopify update the currentPeriodEnd field without generating a webhook for app_subscriptions/update ?
I don’t think Shopify actually stores or updates the billing dates. These dates can be easily calculated based on when the user subscribed to the plan.
I think there’s a miss understanding here, there update webhook is when the subscription is updated e.g. the customer changes plans or cancels. Not when a calculated field is updated.
You can access the currentPeriodEnd via GraphQL on the currentAppInstallation if you need it.
I would suggest instead checking/using the subscription status as you will get an webhook if that changes.
