Use this skill when you are choosing between integrating RevenueCat or wiring Google Play Billing Library (PBL) directly, and you need to see which concerns disappear, which shift, and which still land on your team. The decision covers both the Android client and any server side infrastructure that supports subscriptions or one time purchases.
Typical questions this skill answers:
Before reading the tables, identify what you are actually evaluating. Sort your requirement into one of these buckets and jump to the matching section:
| Bucket | Examples | Go to |
|---|---|---|
| Client purchase plumbing | BillingClient, listeners, acknowledgement, consumption | Client side table |
| Server purchase truth | Token validation, RTDN, entitlement state machine | Server side table |
| Out of scope for either | Auth, your user DB, paywall UI, push | Your responsibility table |
If the concern is split (for example, RevenueCat verifies the token but you still need to gate premium content on your API), you own the integration glue even though the verification itself is handled.
| Concern | Raw PBL | RevenueCat |
|---|---|---|
| BillingClient setup and configuration | You write | Handled internally |
| Connection lifecycle and reconnection | You write | Handled internally |
| PurchasesUpdatedListener | You write | Replaced by purchase callbacks |
| queryProductDetailsAsync() | You write | Replaced by awaitOfferings() / awaitGetProducts() |
| launchBillingFlow() | You write | Called internally by awaitPurchase() |
| Acknowledgement after purchase | You write | Handled automatically |
| Consumption of consumables | You write | Handled automatically (mark product as consumable in dashboard) |
| queryPurchasesAsync() on launch | You write | Handled internally on connection |
| Retry logic for transient errors | You write | Handled internally by SDK |
| BillingResponseCode handling | You write | Abstracted to PurchasesErrorCode |
| In-app payment recovery messages | You write | Automatic (showInAppMessagesAutomatically = true) |
| Subscription option selection for offers | You write | defaultOption selected automatically |
| Concern | Raw PBL | RevenueCat |
|---|---|---|
| Google Play Developer API integration | You build | RevenueCat backend |
| Service account credential management | You manage | Configured once in RC dashboard |
| Receipt verification on every purchase | You build | Automatic |
| Purchase token validation and deduplication | You build | RevenueCat backend |
| linkedPurchaseToken chain traversal | You build | RevenueCat backend |
| RTDN processing and dispatch | You build | RevenueCat processes, sends webhooks |
| Cloud Pub/Sub setup | You set up | Not needed |
| Subscription state machine on backend | You build | CustomerInfo computed by RC |
| Entitlement computation across 7 states | You build | isActive computed by RC |
| Grace period / account hold tracking | You build | billingIssueDetectedAt |
| Cancellation with access-until-expiry logic | You build | isActive + unsubscribeDetectedAt |
| Price cohort tracking | You build | RC backend handles |
| Product-to-entitlement mapping | You build | Configured in RC dashboard |
| Concern | Notes |
|---|---|
| User authentication system | You bring your own; pass user ID to RC |
| Your own database of users | RC is not your primary user database |
| Premium content server side | Verify via RC REST API or webhooks |
| Webhook receiver endpoint | You build; RC sends, you receive |
| Play Console product creation | Still done in Play Console |
| Subscription deferral | Direct Google Play API call |
| Subscription revocation | Direct Google Play API call |
| Alternative billing programs | Limited RC support; may need raw PBL |
| App UI (paywalls, onboarding) | You build (RC Paywalls UI optional) |
| Push notifications for payment issues | You build on top of webhook events |
Use these rules to convert the tables into a decision:
appUserID and verifying entitlements server side via the REST API or webhooks is still on you.Quick gate:
need custom RTDN pipeline? -> raw PBL only if you must own it end to end
need deferral or revocation? -> keep a raw PBL path for those API calls
need fast time to production? -> RevenueCat, then add raw PBL escape hatches laterccfc038
If you maintain this skill, you can claim it as your own. Once claimed, you can manage eval scenarios, bundle related skills, attach documentation or rules, and ensure cross-agent compatibility.
