## About

# Cancellations, Pauses, and Winback

Detect cancellation, pause, and winback states on Android by reading `CustomerInfo`. Most of these events are passive: your app observes them rather than initiates them. Open Google Play's manage screen with `managementURL`. Look up the pause resume date from the REST API.

## Phase 1: Scope

Decide what state you need to surface to the user.

| State | Signal in CustomerInfo | Notes |
|---|---|---|
| Canceled, still has access | `entitlement.unsubscribeDetectedAt != null` and `isActive == true` | Show "ends on [expirationDate]" |
| Billing issue (grace or hold) | `entitlement.billingIssuesDetectedAt != null` | Payment failed, recovery in progress |
| Paused | `entitlement.isActive == false` while product is still owned | Resume date requires REST API |
| Active and renewing | `entitlement.willRenew == true` | Normal state |

Backend win back campaign segmentation uses the `CANCELLATION` webhook `cancel_reason` field (`UNSUBSCRIBE`, `BILLING_ERROR`, `DEVELOPER_INITIATED`, `PRICE_INCREASE`).

## Phase 2: Prepare

Confirm you already have a fetched `CustomerInfo` from `Purchases.sharedInstance.getCustomerInfo(...)` or a listener. You do not need to call `BillingClient.queryPurchasesAsync` with `setIncludeSuspendedSubscriptions(true)`. RevenueCat resolves pause state from the server side subscription state.

Rules:

- `managementURL` is already `Uri?`. Pass it straight to the Intent. Do not call `Uri.parse(url.toString())`.
- Do not compute access manually from `expirationDate`. Read `isActive` and `willRenew`.
- Pause resume date is not in the SDK. Fetch it from `/v1/subscribers/{app_user_id}` in your backend.

## Phase 3: Execute

### Detect cancellation with remaining access

```kotlin
val entitlement = customerInfo.entitlements["pro_access"]
if (entitlement?.unsubscribeDetectedAt != null && entitlement.isActive) {
    entitlement.expirationDate?.let { expiry ->
        showCancellationBanner(expiry)
    }
}
```

`unsubscribeDetectedAt` is set when RevenueCat receives the `SUBSCRIPTION_CANCELED` RTDN. `isActive` stays `true` until the billing period ends.

### Detect pause

```kotlin
val entitlement = customerInfo.entitlements["pro_access"]
val hasAccess = entitlement?.isActive == true
// When paused, isActive == false. Pause resume date is not in the SDK.
```

### Open the subscription management screen

```kotlin
customerInfo.managementURL?.let { url ->
    startActivity(Intent(Intent.ACTION_VIEW, url))
}
```

`managementURL` is typed as `Uri?`. Use it directly. Wrapping it with `Uri.parse(url.toString())` is redundant and error prone.

### Look up pause resume date via REST

From your backend, call the subscribers endpoint and read `paused_expiration_time_ms` on the subscription:

```bash
curl -H "Authorization: Bearer $RC_SECRET_API_KEY" \
  https://api.revenuecat.com/v1/subscribers/$APP_USER_ID
```

The subscription object contains `paused_expiration_time_ms` when paused. Expose this to your client through your own endpoint.

### Resubscribe before expiry

Google's resubscribe before expiry flow fires `SUBSCRIPTION_RESTARTED`. RevenueCat clears `unsubscribeDetectedAt` and sets `willRenew = true`. No extra code required, just re-read `customerInfo`.

### Resubscribe after expiry

A resubscribe after expiry fires a `RENEWAL` webhook, not `INITIAL_PURCHASE`. Grant entitlement access on both events in your backend handler.

## Phase 4: Verify

| Check | How |
|---|---|
| Cancellation banner shows | Cancel in Play Store, pull fresh `CustomerInfo`, confirm `unsubscribeDetectedAt != null` and `isActive == true` |
| Management deep link opens | Tap the link, verify Play subscriptions screen opens for the correct product |
| Pause is reflected | Pause in Play Store sandbox, confirm `entitlement.isActive == false` |
| Pause resume date | Call `/v1/subscribers/{id}`, confirm `paused_expiration_time_ms` is present |
| Win back accepted | Accept a Play configured win back offer, confirm the purchase surfaces as a normal subscription in `CustomerInfo` |

## Notes

- Deferral and revocation are done through the Google Play Developer API (`purchases.subscriptionsv2.defer`, `purchases.subscriptionsv2.revoke`) from your backend. RevenueCat processes the resulting RTDN and updates `CustomerInfo` automatically.
- Win back campaigns need no SDK code. They are configured in Play Console or the RevenueCat dashboard.
- RevenueCat does not currently emit a dedicated pause webhook. Pause state appears in `CustomerInfo` once the Google Play RTDN is processed.
