Common Webhook Flows

How webhooks are sent from RevenueCat

You’ll receive many Webhooks throughout a subscriber’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 subscriber purchases a product for the first time. A single subscriber may go through this flow multiple times if they purchase multiple products.

Cancellation Flow

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

cancellation flow

Uncancellation Flow

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

Resubscribe Flow

A subscriber 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 subscribers can pause their subscription, allowing them to halt subscription billing. Their entitlement is revoked at the end of the subscription term. If the subscriber 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 subscriber 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 subscriber’s entitlements will be revoked.

If you do have grace periods enabled, the subscriber will retain entitlements as the app store retries the subscriber’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 subscriber 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.

successful conversion flow

Trial Flow (Unsuccessful Conversion)

When a user initially signs up for a subscription with a trial, an INITIAL_PURCHASE webhook is dispatched. If the subscriber 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 subscriber's entitlements will be revoked.

Note: Apple requires subscribers 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

Product Upgrade Flow

If a subscriber upgrades to a higher tier subscription, both a PRODUCT_CHANGE and RENEWAL event will be dispatched and the subscriber will immediately have access to the new entitlements. The subscriber will then be refunded a prorated amount for the remainder of the lower tier subscription’s term.

upgrade flow

Product Downgrade Flow

If a subscriber downgrades from a higher tier product to a lower tier product, a PRODUCT_CHANGE event will immediately be sent, and the user will retain their higher tier entitlements. When the subscriber encounters their next renewal, a RENEWAL event will be dispatched, the user will be billed at the lower product tier’s price, and the user’s entitlements will be replaced by the entitlements from the lower tier product.

downgrade flow

Crossgrade Flow, Same Term Length

If a subscriber crossgrades from one product to another product on the same tier and with the same subscription period, you’ll immediately receive both a PRODUCT_CHANGE and a RENEWAL event. The subscriber will receive the entitlements from the second product, will be billed for the second product, and will receive a prorated refund for the remainder of the first product’s billing period.

crossgrade same term flow

Crossgrade Flow, Different Term Length

If a subscriber crossgrades from one product to another product on the same tier and with different subscription periods, you’ll immediately receive a PRODUCT_CHANGE event. At the end of the first subscription’s billing period, you’ll receive a RENEWAL event and the user will be switched to the second product.

crossgrade different term flow


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.
