Backpack Profile

Comprehensive user profile, referral, and wallet subsystem for Laravel applications that use Backpack. The package ships ready-to-use CRUD panels, API endpoints, referral triggers, wallet management, reward distribution, withdrawal workflows, and a Sanctum-based authentication layer that can be consumed from SPA or mobile clients.

Feature Overview

• Profile lifecycle: automatic profile creation for new users, profile CRUD for admins, REST endpoints for profile self-service.
• Authentication APIs: email/password registration, login, logout, password reset, email verification, and Socialite OAuth flows (Google/Facebook) with Sanctum personal access tokens.
• Referral engine: multi-level referral tree, reward events, trigger registry, reward ledger, and configurable payout logic.
• Wallet subsystem: balance table, ledger journal, hold/release/capture semantics, CurrencyConverter integration, and withdrawal processing workflow.
• Backpack admin UI: CRUD panels for profiles, referrals, rewards, reward events, wallet ledger, withdrawals, and an analytic dashboard with charts.
• Settings integration: configuration groups exposed through the Backpack Settings package (currencies, withdrawal thresholds, trigger configuration, etc.).
• Extensibility hooks: event listeners on user/profile creation, trigger registry, facades/services for programmatic access, publishable assets for overriding views/routes/config.

Requirements

• PHP 8.2+
• Laravel 12.x
• Backpack 6.x (CRUD + Settings packages)
• Laravel Sanctum 4.2+ for API tokens
• Laravel Socialite 5.23+ for social login (optional)
• Database driver that supports JSON columns (MySQL 5.7+/MariaDB 10.2+/PostgreSQL 9.4+)

Installation

1. Install the package

2. Run migrations

   This creates core tables such as ak_profiles, ak_referral_partners, ak_reward_events, ak_rewards, ak_wallet_balances, ak_wallet_ledger, and ak_withdrawal_requests.

3. (Optional) Publish assets

   • Config is copied to config/backpack/profile.php.
   • Views land under resources/views/vendor/profile and resources/views/vendor/backpack/crud.
   • Migrations and route stubs are publishable if you need to customize them heavily.

4. Configure Backpack Settings (recommended)

   Register Backpack\Profile\app\Settings\ProfileSettingsRegistrar inside your Backpack Settings registrar so that referral, wallet, and withdrawal options become editable from the admin UI.

Quick Start Checklist

Database Schema

Note: legacy code still references columns such as firstname, lastname, and addresses. If you rely on these attributes, ensure your schema includes matching columns or adjust the model to align with the published migrations. See IMPROVEMENTS.md for known inconsistencies.

Configuration Highlights

config/backpack/profile.php drives most behavior:

• user_model / profile_model: customize linked Eloquent classes.
• private_middlewares: middleware stack applied to wallet/withdrawal API routes (defaults to ['api', 'auth.api:sanctum']).
• referral_enabled, referral_levels, referral_commissions: legacy defaults for simple multi-level referral payouts.
• points group: toggles the virtual points currency used for wallet operations (key, name, base currency backing the point).
• currencies: list of fiat currencies exposed to the UI; affects select boxes and labels.
• currency_converter: class implementing Backpack\Profile\app\Contracts\CurrencyConverter used by WithdrawalService and referral payouts.
• withdrawal group: enable/disable withdrawals and configure minimum amounts.
• users group: allow self-registration, require email verification, default role/locale.

Backpack Settings extender (ProfileSettingsRegistrar) mirrors these options in a GUI-friendly manner. Ensure the registrar is invoked by the host application so admins can manage referral triggers, currencies, and withdrawal policies.

Backpack Admin Panels

Once the service provider boots, the following routes are available under the Backpack prefix (default /admin):

• profile CRUD (ProfileCrudController): manage user profiles, inspect balances, sponsors, contact data, and explore the full referral tree via the details row.
• rewards list (RewardCrudController): read-only grid of issued rewards, filters by beneficiary type, amount, currency.
• reward-events list (RewardEventCrudController): inspect trigger executions, re-process or create reversal events.
• wallet-ledger list (WalletLedgerCrudController): journal of wallet movements.
• withdrawals list (WithdrawalRequestCrudController): approve/reject/mark paid, view FX and payout metadata.
• profile-dashboard (ProfileDashboardController): dashboard with aggregate stats, chart.js graphs for wallet flows, reward volumes, recent referrals, withdrawals.
• referrals/settings: placeholder for future Settings UI (requires integration with Backpack Settings).

All admin controllers rely on Backpack's CRUD operations, custom columns (e.g., user_card, price, status), and the translation strings shipped under resources/lang/en|ru.

API Surface

Authentication (/api/auth/...)

• POST /api/auth/register
• POST /api/auth/login
• POST /api/auth/logout (Sanctum token required)
• GET /api/auth/me (Sanctum token required)
• POST /api/auth/password/change (Sanctum token required)
• POST /api/auth/password/forgot
• POST /api/auth/password/reset
• POST /api/auth/email/verification-notification (Sanctum token + throttle)
• POST /api/auth/email/resend (throttle)
• GET /api/auth/verify-email/{id}/{hash} (signed link)
• GET /api/auth/oauth/{provider}/url
• GET /api/auth/oauth/{provider}/callback

Responses are JSON-only thanks to ForceJsonResponse middleware. The detailed request/response contract and recommended Nuxt/Auth.js integration steps are documented in AUTH_SYSTEM.md.

Profile (/api/profile/...)

• GET /api/profile (guard auth:profile) — returns ProfileFullResource.
• POST /api/profile/update (currently guarded by auth:sanctum) — updates allowed fields after validation.
• GET /api/profile/referrals (guard auth:profile) — paginated downline list using ProfileTinyResource.

Important: the controller expects an authenticated profile guard but the update route is wired to auth:sanctum. Align guards in your application or adjust the controller as described in IMPROVEMENTS.md.

Wallet & Withdrawals (/api/wallet/...)

Routes are wrapped in middleware from Settings::get('profile.private_middlewares') (defaults to ['api', 'auth.api:sanctum']).

• GET /api/wallet/withdrawals
• POST /api/wallet/withdrawals
• POST /api/wallet/withdrawals/{id}/cancel

WithdrawalService enforces minimum amounts, currency conversion, wallet holds, and ledger bookkeeping. Admin actions (approve/reject/mark paid) are exposed through Backpack routes.

Services & Facades

• Backpack\Profile\app\Services\Profile: high-level API for triggering referral events, reversing events, resolving currencies, and retrieving the configured user model.
• Backpack\Profile\app\Services\ReferralService: core engine that records events, resolves uplines, distributes rewards, and performs reversals.
• Backpack\Profile\app\Services\WithdrawalService: creates withdrawal requests, handles approval/rejection/capture, interacts with wallet balances.
• Backpack\Profile\app\Services\WalletService: implements authorize, capture, void, and balance retrieval on the wallet ledger.
• Backpack\Profile\app\Services\TriggerRegistry: registry for referral triggers implementing Backpack\Profile\app\Contracts\ReferralTrigger.
• Backpack\Profile\app\Services\ProfileFactory: builds Profile instances and resolves sponsor linkage based on referral codes.
• Profile facade (Backpack\Profile\app\Facades\Profile): shortcut to the Profile service.
• Middleware: CaptureReferral, ForceJsonResponse, CheckIfAuthenticateProfile.

All services are container-bound in ServiceProvider. You can override bindings in your application service provider if you need to replace behavior.

Events, Notifications, and Observers

• Events: ProfileCreating, UserCreating fire during model creation; default listeners populate names and (optionally) referral codes.
• Notifications: placeholders for user onboarding (UserRegistred, ReferralRegistred, ReferralBonus, etc.) and withdrawal completion emails.
• Observers: ProfileObserver and TransactionObserver include legacy logic; review them before enabling in production.

Extending the Referral Engine

1. Implement Backpack\Profile\app\Contracts\ReferralTrigger.
2. Register the trigger alias with TriggerRegistry::register($alias, $class), typically from a service provider or module boot method.
3. Configure trigger settings (fixed/percent payouts, actor award, level distribution) via the Backpack Settings UI or config/settings.php.
4. Invoke Profile::trigger($alias, $externalId, $payload, $actorUserId, $opts) whenever an event occurs (e.g., order paid).

Reversals can be created via Profile::reverse(...) or admin UI actions.

Frontend Integration Notes

• Authentication is token-based: clients must send Authorization: Bearer {token} with Sanctum personal access tokens.
• API responses are JSON, validation errors use standard Laravel structure (errors array).
• Email verification is optional and controlled by profile.users.require_email_verification.
• Social login flows expect the frontend to call /oauth/{provider}/url, redirect the browser, and handle /callback with optional redirect back to the SPA.
• AUTH_SYSTEM.md contains step-by-step guidance tailored for Nuxt 3 + Auth.js, including error handling and state transitions.

Testing & Development

• The repository currently ships with placeholder tests under packages/backpack/profile/tests. Update them to use PHPUnit/Pest against the modern package namespace before relying on automated coverage.
• Consider adding feature tests that cover registration, login, referral triggers, withdrawal lifecycle, and admin actions to avoid regressions.

Known Gaps & Roadmap

See IMPROVEMENTS.md for a curated backlog of technical debt and missing functionality (schema mismatches, outdated controllers, guard inconsistencies, missing tests, etc.). Addressing those items is recommended before turning the package into a reusable release.
