Instructions for adding RevenueCat in-app purchases to a mobile app. RevenueCat manages purchase events from Apple's and Google's stores, while Supabase stores the app's credit balance through a webhook.

Use it to set up consumable credit packs or subscriptions, configure store products and the SDK, build a paywall, and process purchase webhooks.

It explains how to keep store purchases, app credits, the paywall, and server-side updates in sync.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00057	$0.04692
Opus 5	$0.00028	$0.02346
Sonnet 5	$0.00011	$0.00938
Haiku 4.5	$0.00006	$0.00469

Security

Grade A, and why

revenuecat scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 534 lines — stays where its author put it; the contents beside it link to each section on GitHub.

RevenueCat Integration

Architecture

App Store Connect / Google Play  ←→  RevenueCat Dashboard
        ↓ purchase events
RevenueCat Webhook  →  Supabase Edge Function  →  profiles.credits
        ↓ SDK
RevenueCatContext (React)  →  PaywallTrigger (root Modal)

RevenueCat is the source of truth for purchases. Supabase is the source of truth for credits. They stay in sync via webhook.

Step 1: Create Products in App Store Connect (iOS)

appstoreconnect.apple.com → My Apps → your app
Left sidebar: Monetization → In-App Purchases → +
Type: Consumable → Create
For each product:
- Product ID: credits_50 / credits_150 (must match exactly across all platforms)
- Reference Name: 50 Credits / 150 Credits
- Price: set your price tier
- Add at least one Localization (English)
- Review Information: upload a screenshot of the paywall (required by Apple — mockup is fine)
- Save

Products will show "Missing Metadata" until your next app submission — this is normal. RevenueCat can read them immediately.

Step 2: Create Products in Google Play Console (Android)

play.google.com/console → your app
Left sidebar: Monetize → In-app products → Create product
For each product:
- Product ID: credits_50 / credits_150
- Name and Description
- Default price
- Status: Active ← required, draft products don't work
Save

Note: Google Play products only work after the app has at least one published release (even internal testing). Purchases will fail in development until then.

Step 3: Set Up RevenueCat Dashboard

Create project + add iOS app

app.revenuecat.com → + New Project
+ Add App → App Store
Bundle ID: your ios.bundleIdentifier
In-App Purchase key (.p8): this is NOT the App Store Connect API key

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
