## Why
During the bank connection flow (Enable Banking) a user picks which
accounts to sync and can skip the rest. Until now there was **no way
back**: a skipped account couldn't be enabled later, a synced account
couldn't be moved or turned off, and accounts the bank added afterwards
were invisible. Skipped accounts aren't persisted anywhere —
`pending_accounts_data` is cleared once mapping completes — so the app
simply forgets they exist.
This adds a per-connection **Manage Accounts** screen that closes that
gap.
## What
- **Known accounts render from the DB** (no provider call). For each
synced account the user can:
- **Stop syncing** → the account is unlinked and becomes a regular
manual account. Non-destructive: it keeps all its imported transactions.
- **Change destination** → move syncing to another compatible manual
account (unlinks the previous holder, links the new one with incremental
sync).
- **Load accounts** button re-fetches the consent's account list from
the provider *on demand* (`getSession` + `getAccount` only for uids we
don't already know) to surface newly available / previously skipped
accounts, which can then be created as new accounts or linked to
existing manual ones.
- The provider is **only ever hit on refresh**; every mutation is
DB-only, so the screen still works (read + rearrange) when the consent
has expired.
### Design notes
- No new column / cache: the default view derives entirely from the
`accounts` table, and refresh is on-demand and ephemeral. Re-fetching is
mandatory anyway (existing connections have no stored snapshot, and only
a live call can reveal accounts the bank added later).
- Scoped to **Enable Banking** for now; the approach is column-free so
extending to the crypto/API-key providers later is trivial.
## Endpoints
- `GET open-banking/connections/{connection}/accounts` — manage screen
(`discoveredAccounts` computed only when `?refresh=1`)
- `POST open-banking/connections/{connection}/accounts/map` — create /
link / change destination for one bank account
- `POST open-banking/connections/{connection}/accounts/{account}/unlink`
— stop syncing
## Testing
- New `ConnectionAccountTest` (7 tests): index props, refresh discovery
(excludes already-synced uids), create,
change-destination/unlink-previous, non-destructive unlink keeps
transactions, ownership 403, account-mismatch 404.
- Full `tests/Feature/OpenBanking` suite green (268), plus pint, eslint,
prettier and the enforced `es` localization test.
## Deliberately skipped
- **Subscription gating** on refresh/map — matches the currently ungated
`disconnect`. Easy follow-up if free users shouldn't trigger live
provider calls.
- Other providers (Enable Banking only, as agreed).
## Why
Syncing was a growing `if/elseif` chain in
`SyncBankingConnectionJob::handle()` plus one private method per
provider. Every new provider meant editing the job, and the file mixed
provider-specific logic with cross-cutting orchestration. This does not
scale to dozens/hundreds of providers.
## What
Introduces a **factory + strategy** pattern:
- **`App\Contracts\BankingConnectionSyncer`** — interface: `sync()`,
`expires()`, `notifiesOnAuthFailure()`.
- **`AbstractBankingConnectionSyncer`** — defaults for the common case
(API-key provider: never expires, notifies on auth failure). A new
provider usually only implements `sync()`.
- **`BankingConnectionSyncerFactory`** — maps `connection.provider` to
its syncer (resolved from the container, so dependencies are injected).
- **Six syncers** — `IndexaCapitalSyncer`, `BinanceSyncer`,
`WiseSyncer`, `BitpandaSyncer`, `CoinbaseSyncer`, `EnableBankingSyncer`.
Each fully owns its provider behavior, including EnableBanking's daily
email and first-sync cutoff.
`SyncBankingConnectionJob` drops from ~520 to ~190 lines and now only
orchestrates: deleted-user/expiry/rate-limit checks, error handling,
retries, logging, and status updates. It asks the syncer `expires()` /
`notifiesOnAuthFailure()` instead of hardcoding provider lists.
### Adding a provider now
1. Create `XSyncer extends AbstractBankingConnectionSyncer` implementing
`sync()`.
2. Add one line to the factory map.
No changes to the job.
## Tests
- Existing job tests (`SyncBankingConnectionJobTest`,
`SyncRetryAndLoggingTest`) migrated through a shared `runSync()` helper
in `tests/Pest.php`; all original assertions preserved.
- New `BankingConnectionSyncerFactoryTest`: provider→syncer resolution,
unknown-provider exception, and the capability flags.
- Full suite green: **1604 passed**, 0 failures. PHPStan clean, Pint
applied.
## Docs
Adds `docs/adding-a-banking-provider.md` — a step-by-step developer
guide (usable by a human or an AI agent) covering the sync provider and
the broader end-to-end integration touchpoints.
## Why
iOS PWAs hand the bank redirect back to the system browser (Safari),
where the app session does not exist. The old `/open-banking/callback`
sat behind `auth` + `verified` middleware, so Safari hit it with no
session → bounced to `/login`, the callback body never ran, and the
connection stayed `pending` forever (4 stale rows observed in prod).
## What
Make the bank connection flow session-independent end to end.
### 1. State-token callback (session-independent)
- `store()` generates `Str::random(40)`, persists it on the connection,
and passes it to `startAuthorization` as `state`.
- `/open-banking/callback` is now **public**. It resolves the connection
from `state_token` (`resolveConnectionFromState`) and derives the owner
from the connection, not the session.
- Connection is finalized server-side (`session_id`, status,
`state_token = NULL`) before any redirect.
- New migration adds the nullable, unique `state_token` column; the
column is hidden on the model.
### 2. Completion page instead of login bounce
When the callback runs without a session (the Safari case), the
connection is already finalized server-side. Instead of bouncing the
user to `/login`, render a standalone "go back to the app" page — their
session lives in the PWA, not here.
- New page `resources/js/pages/open-banking/connection-complete.tsx`
(success / error states, dark mode).
- `finishRedirect()` renders the page when `!Auth::check()`; logged-in
users still get the normal redirect.
### 3. Onboarding: land on the connections step + poll cross-browser
- A logged-in user finishing the flow lands straight on the onboarding
connections step (`?step=create-account`), now resolved server-side via
a validated `initialStep` prop so the step is deterministic.
- While on that step the page polls every 4s (`usePoll`, `only:
['accounts']`), so a connection finalized in another browser (PWA →
Safari) shows up without a manual refresh.
## Flow
```
POST /authorize → stateToken = Str::random(40)
→ startAuthorization(state = stateToken)
→ create BankingConnection(pending, state_token)
EnableBanking → callback?code&state=stateToken (PUBLIC, no session needed)
→ find connection WHERE state_token = state
→ createSession(code) → finalize (session_id, status, state_token = NULL)
→ session present? redirect to connections step / mapping
: render "go back to the app" completion page
PWA (logged in) → onboarding?step=create-account → polls accounts every 4s
```
## Tests
36 passing. Covers:
- state-token persistence and session-less finalization
- owner resolved from the connection regardless of who is authenticated
- completion page rendered (success + error) when no session; login
fallback when no connection resolves
- logged-in user redirected directly to the onboarding connections step
- `?step=create-account` lands on that step; unknown step falls back to
default
## Summary
- Adds `banking:backfill-ibans` artisan command to backfill null `iban`
values on Enable Banking accounts by calling `GET /accounts/{uid}` for
each affected account.
- Adds `getAccount()` to `BankingProviderInterface` and
`EnableBankingProvider`.
- 9 feature tests covering all paths: happy path, no-IBAN skip, dry-run,
user/connection filters, API failure handling.
## Why
Accounts connected before
[#220](https://github.com/whisper-money/whisper-money/pull/220) was
deployed have `null` IBANs. Without IBANs, reconnects fall back to
positional matching which is less reliable. Running this command once in
production populates the IBAN for all existing accounts so future
reconnects use the safer IBAN-based strategy.
## Usage
```bash
# Dry run first
php artisan banking:backfill-ibans --dry-run
# Run for all accounts
php artisan banking:backfill-ibans
# Scope to a specific user or connection
php artisan banking:backfill-ibans --user=user@example.com
php artisan banking:backfill-ibans --connection=<connection-id>
```
## Summary
- Adds **EnableBanking** as the first open banking provider, allowing
users to connect real bank accounts and automatically sync transactions
and balances
- Uses a **`BankingProviderInterface`** contract so future providers
(Plaid, GoCardless, etc.) can be added by implementing the same
interface
- Feature-flagged behind the **`open-banking`** Pennant flag (default:
off)
- Connected accounts are **unencrypted** and transactions have `source =
'enablebanking'`
### What's included
**Backend:**
- `BankingProviderInterface` contract + `EnableBankingProvider`
implementation (JWT RS256 auth)
- `BankingConnection` model with full lifecycle (pending →
awaiting_mapping → active → expired/revoked/error)
- `TransactionSyncService` — pagination, deduplication by
`external_transaction_id`, amount/date mapping
- `BalanceSyncService` — preferred balance type selection (CLBD → ITAV
fallback)
- Authorization flow: start auth → bank redirect → callback → session
creation → account mapping → sync
- `SyncBankingConnectionJob` (unique per connection, 3 retries) +
scheduled every 6 hours
- `banking:sync` artisan command
- 5 migrations: `banking_connections` table, account fields, transaction
`external_transaction_id`, `pending_accounts_data`, `linked_at`
**Frontend:**
- Manual vs Connected account choice in the create account dialog
- Multi-step bank connection dialog (country → bank selection →
confirmation → redirect)
- Account mapping page — map discovered bank accounts to existing
accounts, create new ones, or skip
- Settings/Connections page with status badges, sync/disconnect actions
- "Connected" badge on linked accounts in settings
**Tests:**
- 49 tests covering feature flags, controllers, account mapping,
transaction sync, balance sync, deduplication, and pagination
### Feature Flags
This PR introduces **two Pennant feature flags**:
1. **`open-banking`** — Gates the entire open banking feature
(institutions endpoint, authorization flow, connections page). When
disabled, all open banking routes return 404.
2. **`account-mapping`** — Controls whether users see an intermediate
account mapping step after connecting a bank. When **enabled**, users
are redirected to a mapping page where they can choose to create new
accounts, link to existing ones, or skip each discovered bank account.
When **disabled**, all discovered accounts are automatically created
(original behavior). Linked accounts only sync transactions from their
last transaction date and only update the current balance from the
provider (no historical balance calculation or daily balance tracking).
Enable per-user:
```bash
php artisan feature:enable open-banking user@example.com
php artisan feature:enable account-mapping user@example.com
```
Enable for all users:
```bash
php artisan feature:enable open-banking all
php artisan feature:enable account-mapping all
```
## Test plan
- [x] Enable feature flag: `php artisan feature:enable open-banking`
- [x] Verify "Connected" option appears in create account dialog
- [x] Start authorization flow and verify redirect to bank
- [x] With `account-mapping` **disabled**: verify callback creates
accounts directly and dispatches sync
- [x] With `account-mapping` **enabled**: verify callback redirects to
mapping page
- [x] Test mapping page: create new, link to existing, and skip actions
- [x] Verify linked accounts sync only from last transaction date and
only update current balance
- [x] Verify connections page shows "Setup Required" badge for
awaiting_mapping status
- [x] Run `php artisan banking:sync` and verify transactions sync
- [x] Verify connections page shows status, sync, and disconnect actions
- [x] Run full test suite: `php artisan test --compact`
