# Subscriptions and Recurly Integration

## Scope
This doc summarizes how subscription and Recurly behavior currently works across `web` and `ruby`, and what is currently tested.

## Runtime Flow

### UI/API entry points (`web`)
Frontend calls are in `web/app/assets/javascripts/jam_rest.js`:
- `POST /api/recurly/update_payment` (`updatePayment`)
- `POST /api/recurly/change_subscription` (`changeSubscription`)
- `GET /api/recurly/get_subscription` (`getSubscription`)
- `POST /api/recurly/create_subscription` (`createSubscription`, legacy path)
- `POST /api/recurly/cancel_subscription` (`cancelSubscription`)

Primary subscription UI logic:
- `web/app/assets/javascripts/react-components/CurrentSubscription.js.jsx.coffee`
  - Plan changes call `rest.changeSubscription(...)`.
- `web/app/assets/javascripts/react-components/AccountPaymentHistoryScreen.js.jsx.coffee`
  - Payment method updates tokenize in Recurly.js and call `rest.updatePayment({recurly_token})`.

### API controller (`web/app/controllers/api_recurly_controller.rb`)
Main endpoints and behavior:
- `change_subscription_plan`
  - Sets `desired_plan_code` via `RecurlyClient#update_desired_subscription`.
  - If plan is blank, intends free tier/cancel behavior.
  - Returns effective and desired plan status payload.
- `update_payment`
  - Uses token to ensure/update account billing.
  - Immediately calls `RecurlyClient#handle_create_subscription(current_user, current_user.desired_plan_code, account)`.
  - This is the key bridge that makes payment-first and plan-first converge.
- `get_subscription`
  - Returns subscription state + account billing presence + plan metadata.
- `create_subscription`
  - Legacy direct purchase path via `Sale.purchase_subscription`.
- `cancel_subscription`
  - Cancels tracked subscription and returns subscription json.

Also in this controller, Recurly-backed commerce exists for non-plan purchases:
- `place_order` -> `Sale.place_order` (JamTracks/gift cards).

### Recurly client and business logic (`ruby/lib/jam_ruby/recurly_client.rb`)
Main responsibilities:
- Account lifecycle: `create_account`, `get_account`, `update_account`, `update_billing_info`, `find_or_create_account`.
- Subscription lifecycle:
  - `update_desired_subscription` (records user intent, cancels on free, or calls `handle_create_subscription` for paid plan).
  - `handle_create_subscription` (creates/reactivates subscription, sets `recurly_subscription_id`, effective plan behavior, trial handling, playtime reset).
  - `create_subscription` (reactivation path first; otherwise new subscription create).
  - `find_subscription` (repairs missing local `recurly_subscription_id`, removes expired references).
- Ongoing sync:
  - `sync_subscription(user)` reconciles local plan with trial/admin-license/account/subscription/past_due state.
  - `sync_transactions` imports successful subscription purchases for affiliate distributions and advances `GenericState.recurly_transactions_last_sync_at`.

### Hourly background sync
- `ruby/lib/jam_ruby/resque/scheduled/hourly_job.rb` executes hourly and calls:
  - `User.hourly_check`
- `ruby/lib/jam_ruby/models/user.rb`:
  - `hourly_check` -> `subscription_sync` + `subscription_transaction_sync`
  - `subscription_sync` selects eligible users and calls `RecurlyClient#sync_subscription`.
  - `subscription_transaction_sync` calls `RecurlyClient#sync_transactions` from last sync timestamp.

## Other Recurly Usage
- `ruby/lib/jam_ruby/models/sale.rb`
  - Recurly invoice/adjustment flow for JamTrack/gift card purchasing (`place_order` and related methods).
  - `purchase_subscription` legacy subscription purchase flow.
- `ruby/lib/jam_ruby/models/recurly_transaction_web_hook.rb`
  - Parses webhook XML and stores transaction records.
- `web/app/controllers/api_recurly_web_hook_controller.rb`
  - Receives webhook, validates type via `RecurlyTransactionWebHook.is_transaction_web_hook?`, persists via `create_from_xml`.

## Current Tests (Recurly/Subscription Focus)

### `web/spec/requests/api_recurly_web_hook_controller_spec.rb` (active)
- `no auth`: webhook endpoint requires basic auth (401 without it).
- `succeeds`: valid successful-payment webhook returns 200.
- `returns 422 on error`: invalid account/user mapping raises and returns 422.
- `returns 200 for unknown hook event`: unknown xml root is ignored and still returns 200.

### `web/spec/controllers/api_recurly_spec.rb` (mostly disabled/commented)
- Contains setup for account CRUD controller tests.
- All actual examples are commented out; effectively no active `ApiRecurlyController` coverage here.

### `ruby/spec/jam_ruby/models/recurly_transaction_web_hook_spec.rb` (active)
- `deletes jam_track_right when refunded`: asserts webhook parse path for refund events and related sale links (current expectation checks right remains present).
- `deletes jam_track_right when voided`: same for void (current expectation checks right remains present).
- `successful payment/refund/failed payment/void/not a transaction web hook`: validates root-name recognition in `is_transaction_web_hook?`.
- `create_from_xml` successful payment/refund/void: verifies persisted transaction fields map from XML correctly.

### `ruby/spec/jam_ruby/recurly_client_spec.rb` (active)
Examples:
- `can create account`
- `can create account with errors`
- `with account` group:
  - `can find account`
  - `can update account`
  - `can update billing`
- `can remove account`

### `ruby/spec/jam_ruby/models/user_subscriptions_spec.rb` (active)
Examples:
- User sync group:
  - `empty results`
  - `user not in trial`
  - `revert admin user down`
- Subscription transaction sync (network + mocked):
  - `fetches transactions created after GenericState.recurly_transactions_last_sync_at`
  - `creates AffiliateDistribution records for successful recurring transactions`
  - `does not create AffiliateDistribution for same transaction previously been created`
  - `does not create AffiliateDistribution records when there is no affiliate partner`
  - `does not create AffiliateDistribution if out of affiliate window`
  - `assigns correct affiliate partner`
  - `updates affiliate referral fee`
  - `change affiliate rate and updates referral fee`
  - `sets subscription product_type`
  - `sets subscription product_code`
  - `does not error out if begin_time is nil`
  - `changes GenericState.recurly_transactions_last_sync_at`

## Coverage Gaps Right Now
- No active request/controller coverage for `ApiRecurlyController` subscription endpoints:
  - `update_payment`, `change_subscription_plan`, `get_subscription`, `cancel_subscription`.
- Recurly sync has active coverage, but still needs broader hourly decision-tree cases for cancellations/past-due/time-based lifecycle transitions.
- No active browser test asserting payment-first and plan-first flows converge to charge/start-subscription behavior.
- No active automated coverage for first-free-month gold behavior over time progression.

## Live Recurly Internet Tests
- Added active live integration spec (opt-out via env var):
  - `ruby/spec/jam_ruby/integration/recurly_live_integration_spec.rb`
- What it verifies against real Recurly API responses:
  - `RecurlyClient#find_or_create_account` and `#get_account` create/fetch a real account and parse billing/account fields.
  - `RecurlyClient#update_desired_subscription` creates a paid subscription (`jamsubgold`) and returns parsed subscription data.
  - `RecurlyClient#payment_history` and `#invoice_history` return parsed hash arrays from live response bodies.
- How to run:
  - default (runs live): `cd ruby && bundle exec rspec spec/jam_ruby/integration/recurly_live_integration_spec.rb`
  - opt-out: `cd ruby && SKIP_LIVE_RECURLY=1 bundle exec rspec spec/jam_ruby/integration/recurly_live_integration_spec.rb`
  - Optional credential override:
    - `RECURLY_PRIVATE_API_KEY=... RECURLY_SUBDOMAIN=...`
- Current credential status discovered during validation:
  - Keys configured in `web/config/environments/test.rb` (`jamkazam-test`) return `HTTP Basic: Access denied`.
  - Working sandbox/development combo in-repo for live tests: key `55f2...` with subdomain `jamkazam-development`.

## Regression Found While Reviving Tests
- `RecurlyClient#update_account` was broken against the current Recurly gem API.
  - Previous code called `account.update(...)`, which no longer exists on `Recurly::Account`.
  - Fixed code now calls `account.update_attributes(...)`.
  - This was detected by reviving and running `ruby/spec/jam_ruby/recurly_client_spec.rb`.
