laravel-coupon
mrsuner/laravel-coupon is an official companion package for the Laravel
API Boilerplate. It owns the coupon lifecycle — generation, validation and
redemption recording — and nothing else. It has no knowledge of your billing
system, subscription engine or application-specific business logic.
The boundary is enforced by a single architectural rule:
The package fires
CouponRedeemedand stops. Your application listens and acts.
This means:
- No dependency on
laravel/cashier,laravel/cashier-paddleor any billing package. - No dependency on your
Order,SubscriptionorCreditmodels. - Any SaaS — on the boilerplate or a plain Laravel app — can install it regardless of its billing stack.
What connects the package to your business logic is one event class
(CouponRedeemed) and one public
service (CouponService).
Everything else is internal.
Works standalone or with the boilerplate
The core — CouponService, the models and the CouponRedeemed event — is
plain Laravel and runs in any application. The admin API auto-wires into the
boilerplate’s Internal Admin stack when it detects it, and
falls back to a Sanctum-authenticated stack on a vanilla Laravel app. See
Configuration.
What it does
| Concern | Detail |
|---|---|
| Code generation | Random codes, bulk generation, configurable prefix/suffix/length |
| Code validation | Expiry, max uses, per-user limit, active flag |
| Redemption recording | Writes a redemption row, increments the counter, fires an event |
| Admin API | Full CRUD for codes + redemption lists under /internal/admin/v1/ |
CouponRedeemed event |
Fired after a committed redemption; carries the coupon and redeemer |
CouponService |
generate(), generateBulk(), validate(), redeem() |
What it deliberately leaves to you
| Concern | Why |
|---|---|
| Discount application | Business-specific — handled by your event listener |
| Stripe / Paddle integration | Your responsibility, decoupled via the event |
| Order / invoice modification | Outside the package boundary |
| User-facing redeem endpoint | You wire CouponService::redeem() into your own controller |
