Common Webhook Flows

You’ll receive many Webhooks throughout a customer’s journey in your app. We’ve compiled a list of several common event flows to illustrate the events you might receive in some common scenarios.

Subscription Lifecycle

Initial Purchase Flow

This flow occurs each time a customer purchases a product for the first time. A single customer may go through this flow multiple times if they purchase multiple products.

Cancellation Flow

When a customer cancels their subscription, a CANCELLATION webhook is sent. At the end of the billing cycle, an EXPIRATION webhook is sent and entitlements are revoked.

Uncancellation Flow

Uncancellations occur when a customer cancels their subscription and then resubscribes before the subscription’s expiration occurs. In this scenario, the customer never loses entitlements.

Resubscribe Flow

A customer can resubscribe to a subscription if they resume a subscription after it has expired. The webhook event that is triggered depends on the subscription’s platform and subscription group.

Subscription Paused Flow (Android Only)

Android customers can pause their subscription, allowing them to halt subscription billing. Their entitlement is revoked at the end of the subscription term. If the customer unpauses their subscription, they regain entitlements and the subscription’s billing cycle resumes. If you’d like to disable pausing for your subscriptions, you can do so through the Google Play Store Console.

Billing Issue Flow

If a customer with an active subscription encounters a billing issue, RevenueCat will immediately dispatch a BILLING_ISSUE event and a CANCELLATION event with a cancel_reason of BILLING_ERROR.

If you do not have grace periods enabled, you’ll immediately receive an EXPIRATION webhook and the customer’s entitlements will be revoked.

If you do have grace periods enabled, the customer will retain entitlements as the app store retries the customer’s billing method. At the end of the grace period, if billing has not been successful, an EXPIRATION event will be sent and entitlements will be revoked. If billing succeeds at any point during the grace period, you’ll receive a RENEWAL event and entitlements won’t be revoked. (This RENEWAL event may show up before the billing issue in the Customer History timeline. Be sure to check the timestamps on the event pages.)

It’s important to note that the BILLING_ISSUE, CANCELLATION, and EXPIRATION (if no grace period is involved) webhooks are dispatched in order at the same time, so it is unlikely but possible to receive these events in a different order than described here due to network irregularities.

Subscription Extended Flow

If a subscription gets extended, when its expiration changes from a future date to a greater future date, RevenueCat will immediately dispatch a SUBSCRIPTION_EXTENDED event.

This event is fired when a Apple App Store or Google Play Store subscription is extended through the store's API. On the Google Play Store, this event can also sometimes fire when Google defers charging for a renewal by less than 24 hours (for unknown reasons). In this case, you will receive a SUBSCRIPTION_EXTENDED webhook, followed by either a RENEWAL or BILLING_ISSUE webhook within the next 24 hours.

Trial Flows

Trial Flow (Successful Conversion)

When a user initially signs up for a subscription with a trial, an INITIAL_PURCHASE webhook is sent with a period_type of TRIAL. If the trial period for a subscription lapses without the customer canceling the subscription, the trial converts into an active subscription. At this point, a RENEWAL event is dispatched and the user is billed for the subscription for the first time.

Trial Flow (Unsuccessful Conversion)

When a user initially signs up for a subscription with a trial, an INITIAL_PURCHASE webhook is dispatched. If the customer cancels their subscription at any point during the trial period, a CANCELLATION event is sent, but the user will retain entitlement access for the remainder of the trial’s duration. Once the trial duration elapses, an EXPIRATION event will be sent and the customer's entitlements will be revoked.

Note: Apple requires customers to cancel within 24 hours of the trial’s expiration. If a user cancels less than 24 hours before the trial expires, you may unexpectedly receive a CANCELLATION event followed by a RENEWAL event.

Product Changes

Immediate Product Change

In the case of an immediate product change, both a PRODUCT_CHANGE and RENEWAL event will be dispatched and the customer will immediately have access to the new entitlements. Depending on the store and the proration setting, the customer might be charged the full or prorated amount for the new product, and/or be refunded a prorated amount for the remainder of the lower tier subscription’s term, and/or the period for the new product might have a prorated duration.

Immediate changes occur:

  • For upgrades on the Apple App Store (new product is in a higher tier of the same subscription group)
  • For crossgrades of the same term length on the Apple App Store (new product is in the same tier of the same subscription group)
  • On the Google Play Store, for all proration modes except DEFERRED (ie. all proration modes starting with IMMEDIATE)
  • For immediate product changes in Stripe. Please note: The RENEWAL event may show the same purchased_at_ms as the original subscription (ie. t₀), because that is how Stripe represents the status of the subscription after the product change.

Product Change at Period End

In the case of a product change at period end, a PRODUCT_CHANGE event will immediately be sent informing of the upcoming product change. The customer will retain their entitlement based on the original product. When the customer encounters their next renewal, a RENEWAL event will be dispatched, the user will be billed at the new product's price, and the user’s entitlements will be replaced by the entitlements from the new product.

Changes at period end occur:

  • For downgrades on the Apple App Store (new product is in a lower tier of the same subscription group)
  • For crossgrades of a different term length on the Apple App Store (new product is in the same tier of the same subscription group)
  • On the Google Play Store, for the proration mode DEFERRED
  • For scheduled product changes in Stripe

Transfer Flow

If user 1 logs in to your app, makes a purchase and logs out, and then user 2 logs in on the same device with the same underlying App/Play Store account and restores their purchases, you’ll receive a TRANSFER event and the entitlements will be removed from user 1 and added to user 2. This behavior only occurs if your project’s restore behavior is set to transfer.
