RevenueCat sends webhooks in response to events that occur in your app. This page defines those event types and the data contained in each webhook.

For sample payloads, see Sample webhook events.

Events format

Webhook events are serialized in JSON. The body of a POST request to your server will contain the serialized event, as well as the API version.

Event types

Each group of events below links to its field descriptions, lists its event descriptions, and then displays a table showing store compatibility or feature availability (✅ = supported, ❌ = not supported).

Dashboard test

Applicable fields: Common fields · Subscriber identity · Subscription lifecycle

• TEST — RevenueCat issued a test event.
  • This event uses a purchase-like sample payload and isn't persisted in production.

Webhook Event Type	App Store	Google Play	Amazon	Stripe	Promo	Roku	Web Billing
TEST	✅	✅	❌	❌	❌	❌	❌

Subscription lifecycle purchases

Applicable fields: Common fields · Subscriber identity · Subscription lifecycle

• INITIAL_PURCHASE — A new subscription was purchased.
• RENEWAL — An existing subscription was renewed, or a lapsed user resubscribed.
• CANCELLATION — A subscription or non-renewing purchase was canceled or refunded.
  • In the case of refunds, a subscription's auto-renewal setting may still be active. See cancellation reasons for more details.
  • In the case of subscription refunds, this event fires only when the latest subscription period is refunded; refunds for earlier periods do not trigger it.
• UNCANCELLATION — A non-expired canceled subscription was re-enabled.
• NON_RENEWING_PURCHASE — A customer has made a purchase that won't auto-renew.
• SUBSCRIPTION_PAUSED — The subscription was scheduled to pause at the end of the current period.
  • Don't revoke access on this event. Revoke access only on EXPIRATION with expiration reason SUBSCRIPTION_PAUSED.
• EXPIRATION — A subscription has expired.
  • The associated user's access should be removed.
  • With Platform Server Notifications configured, this event occurs within seconds to minutes of expiration. Without notifications, the event might be delayed by approximately 1 hour.
• BILLING_ISSUE — An attempt to charge the subscriber failed.
  • This doesn't mean the subscription has expired.
  • You can safely ignore this event if you listen for CANCELLATION with cancel_reason=BILLING_ERROR.
• PRODUCT_CHANGE — A subscriber has changed the product of their subscription.
  • This doesn't mean the new subscription is in effect immediately. See Managing Subscriptions for more details on updates, downgrades, and crossgrades.
• SUBSCRIPTION_EXTENDED — An existing subscription was extended.
  • The expiration date of the current subscription period was pushed back.
  • This event is fired when an App Store or Google Play subscription is extended through the store's API.
  • On Google Play, this event can also fire when Google defers charging for a renewal by less than 24 hours (for unknown reasons). You may then receive RENEWAL or BILLING_ISSUE within the next 24 hours.
• REFUND_REVERSED — A refund was reversed.
• INVOICE_ISSUANCE — A new, unpaid invoice was issued.
  • A new invoice was created for a subscription or non-renewing purchase that hasn't yet been paid.
  • This only applies to Web Billing purchases, both for new checkout purchases and subscription renewals.

Transfer

Applicable fields: Common fields · Transfer

• TRANSFER — A transfer of transactions and entitlements was initiated between App User ID(s).
  • The webhook is sent only for the destination user, although the event appears in both customer histories. The event body is identical for both users.
  • When a transfer webhook is sent, a separate PURCHASE_REDEEMED webhook might also be sent for Web Billing redemptions that result in a transfer.

TRANSFER	✅	✅	✅	✅	❌	✅	✅

Temporary entitlement grant

Applicable fields: Common fields · Temporary entitlement grant

• TEMPORARY_ENTITLEMENT_GRANT — RevenueCat issued a temporary outage grant to a customer.
  • RevenueCat was temporarily unable to validate a purchase with the store and granted a short-term entitlement (at most 24 hours). This prevents customers from being denied access during exceptional situations, such as partial app store outages.
  • After connectivity is restored, if validation succeeds, expect a regular INITIAL_PURCHASE. If validation fails, expect an EXPIRATION event for the temporary entitlement grant.
  • Because this event is dispatched during limited connectivity, it contains less information than a regular purchase event. In particular, it excludes subscription lifecycle or subscriber identity fields beyond app_user_id.

Webhook Event Type	App Store	Google Play	Amazon	Stripe	Promo	Roku	Web Billing
TEMPORARY_ENTITLEMENT_GRANT	✅	✅	✅	✅	❌	✅	❌

Virtual currency transaction

Applicable fields: Common fields · Subscriber identity · Virtual currency transaction

• VIRTUAL_CURRENCY_TRANSACTION — A virtual currency transaction occurred.
  • Purchases and refunds can both trigger this event.
  • For subscriptions that grant virtual currency, this event is sent for the entire subscription lifecycle whenever there is an adjustment to be made to the currency balance. This includes the initial purchase, renewals, and refunds.
  • This event provides details about the virtual currency adjustment, including the amount, currency type, and source of the change.

Webhook Event Type	App Store	Google Play	Amazon	Stripe	Promo	Roku	Web Billing
VIRTUAL_CURRENCY_TRANSACTION	✅	✅	❌	✅	❌	❌	✅

Experiment enrollment

Applicable fields: Common fields · Subscriber identity · Experiment enrollment

• EXPERIMENT_ENROLLMENT — A customer was enrolled in an experiment.
  • This event isn't associated with a store.
  • app_id is usually excluded. It is included only when enrollment is linked to a dashboard store app (for example, when the SDK has reported last-seen app config data).

Webhook Event Type	App Store	Google Play	Amazon	Stripe	Promo	Roku	Web Billing
EXPERIMENT_ENROLLMENT	✅	✅	✅	✅	✅	✅	✅

Purchase redemption

Applicable fields: Common fields · Purchase redemption

• PURCHASE_REDEEMED — A Web Billing purchase was redeemed and associated with an App User ID.
  • This fires when a user opens a redemption deep link in your app.
  • If the redemption results in a transfer, this is fired in addition to TRANSFER.

PURCHASE_REDEEMED	❌	❌	❌	❌	❌	❌	✅

Paywall UI

Applicable fields: Common fields · Paywall UI

Paywall UI events are sent when a customer interacts with a RevenueCat Paywall, if Paywall events are enabled for the webhook integration. These events are not purchase lifecycle events and don't include transaction fields such as product_id, price, or transaction_id.

The webhook type value uses the default event names below unless you configure custom Paywall event names in the webhook integration.

• PAYWALL_IMPRESSION — A paywall was displayed to a customer.
• PAYWALL_CLOSE — A paywall was closed by a customer.
• PAYWALL_CANCEL — A customer dismissed the payment confirmation on a paywall.

Applicable fields: Common fields · Subscriber identity · Price increase consent

The event fields are grouped into related attributes and referenced from the event type groups above. Use the Included column when building parsers:

• Sometimes — The key is only included when data is available; it may be omitted entirely from the payload.
• (blank) — Nested field under a parent array or object. See the parent row for when the key is included.

Parse defensively: treat Sometimes fields as optional keys, and don't assume Always fields are non-null. Some event types omit fields listed in a group, as noted in each section.
