# Monetization (web Stripe + native RevenueCat)

## Channels

| Runtime | Checkout / manage | Ledger |
|---------|-------------------|--------|
| Web (`!isNativePlatform`) | Stripe Checkout + Customer Portal via `/finance/...` | Stripe webhooks |
| Native Capacitor | RevenueCat IAP (`@revenuecat/purchases-capacitor`) | RevenueCat webhooks → same invoice/payment tables |

FE displays whatever `/finance/invoices/` (and subscription) returns after refresh. Provider badge uses `provider` + `revenuecat_store`.

## App user id

RevenueCat `appUserID` = Django user pk as string.

1. Prefer `id` from `/user/get/` (serializer returns all model fields).
2. Else JWT `user_id` claim (`SIMPLE_JWT.USER_ID_CLAIM`).

Backend webhook resolver accepts numeric pk (or email fallback).

## Mobile env keys

In `.env.mobile`:

- `REACT_APP_REVENUECAT_APPLE_API_KEY`
- `REACT_APP_REVENUECAT_GOOGLE_API_KEY`
- `REACT_APP_REVENUECAT_OFFERING_ID` (optional)

Package identifiers in the RC dashboard should include plan slugs (e.g. `founders`) so `purchasePlan(planSlug)` can match packages/products. Optional backend `REVENUECAT_PRODUCT_PLAN_MAP` maps product id → plan slug.

## Auth hooks

- `Purchases.configure` once on native (first purchase / logIn).
- `logIn(appUserID)` after SignIn / SignUp / AuthCallback / AccountContext load.
- `logOut` on Header2 sign-out and Delete account.
