+# Payments Integration (Moyasar, Webhooks, Idempotency)
+
+This ExecPlan is a living document. The sections `Progress`, `Surprises & Discoveries`, `Decision Log`, and `Outcomes & Retrospective` must be kept up to date as work proceeds.
+
+The requirements for ExecPlans live in `PLANS.md` at the repository root. This document must be maintained in accordance with that file.
+
+## Purpose / Big Picture
+
+After this change, the backend can create Moyasar payments, track their state transitions, and reconcile them via webhooks in an idempotent and auditable way. A user can create a booking payment and see it progress from initiated to paid or failed. You can see it working by creating a payment, receiving a webhook callback that marks it as paid, and observing the payment record transition with a recorded provider reference and idempotency key.
+
+## Progress
+
+- [x] (2026-02-28 14:35Z) Created ExecPlan for payments integration (Moyasar + webhooks + idempotency).
+- [x] (2026-02-28 15:05Z) Inspected payments models/endpoints and aligned naming with Moyasar scaffolding.
+- [x] (2026-02-28 15:20Z) Defined payment state model extensions and idempotency tracking fields.
+- [x] (2026-02-28 15:40Z) Implemented payment creation service and API endpoint with provider gateway.
+- [x] (2026-02-28 15:55Z) Implemented webhook endpoint with secret verification and status mapping.
+- [x] (2026-02-28 16:10Z) Added tests for creation, idempotency, and webhook reconciliation.
+- [x] (2026-02-28 16:20Z) Updated `docs/risks.md` to close payment integration gaps once tested.
+
+## Surprises & Discoveries
+
+- Observation: The payments gateway needed an HTTP client dependency, so `requests` was added to backend requirements.
+  Evidence: `ModuleNotFoundError: No module named 'requests'` when running migrations after adding gateway calls.
+
+## Decision Log
+
+- Decision: Model payment state transitions as explicit status changes with audit-friendly timestamps.
+  Rationale: Payment flows must be auditable and deterministic under retries.
+  Date/Author: 2026-02-28, Codex
+- Decision: Require idempotency keys on payment creation requests.
+  Rationale: Prevents duplicate charges when clients retry.
+  Date/Author: 2026-02-28, Codex
+- Decision: Use a dedicated webhook endpoint with signature verification.
+  Rationale: Ensures authenticity of provider callbacks and protects state integrity.
+  Date/Author: 2026-02-28, Codex
+- Decision: Store provider payloads and webhook payloads on the payment record for auditability.
+  Rationale: Helps trace payment transitions without introducing a separate event table yet.
+  Date/Author: 2026-02-28, Codex
+
+## Outcomes & Retrospective
+
+Payment creation, idempotency handling, and webhook reconciliation are implemented for Moyasar. Tests cover creation, idempotency, and webhook status transitions, reducing the largest Phase 1 reliability gap. Refund/capture operations remain future work if required.
+
+## Context and Orientation
+
+Payments live in `backend/apps/payments/` with current models and API endpoints. The system currently stores payment records but does not integrate with Moyasar or reconcile webhooks. Booking flows live in `backend/apps/bookings/` and should link to payments. The project standards require business logic in services and predictable error responses.
+
+## Plan of Work
+
+First, review existing payment models and endpoints to avoid breaking field names. Identify whether `Payment` includes a reference to `Booking`, a `provider_reference`, and a status field. If any are missing, add them along with timestamps for `initiated_at`, `paid_at`, and `failed_at`. Create a migration for the new fields. Ensure status choices include at least `initiated`, `pending`, `paid`, `failed`, and `refunded` if refunds are in scope.
+
+Next, introduce idempotency tracking. Add a `idempotency_key` field to the payment model (unique, indexed) and validate that payment creation requests require it. If a request repeats with the same key, return the existing payment without creating a new provider charge.
+
+Then, implement the Moyasar payment creation service in `backend/apps/payments/services.py`. The service should build the provider request using amount, currency, description, and return URLs, and persist the `provider_reference` (payment id returned by Moyasar). Store the full provider response in a JSON field for audit if available.
+
+Add a dedicated API endpoint for payment creation in `backend/apps/payments/views.py` and `backend/apps/payments/urls.py`. It should:
+
+- Require authentication.
+- Validate booking ownership and amount.
+- Require `idempotency_key`.
+- Call the service to create the provider payment.
+- Return the payment record plus any provider redirect URL if applicable.
+
+Then, implement the webhook endpoint (`/api/payments/webhook/`) with signature verification using Moyasar’s secret. It should parse the event, locate the payment by `provider_reference`, apply an idempotent state transition, and record timestamps. Unknown events should be logged but return 200 to avoid retries if possible.
+
+Finally, add tests in `backend/apps/payments/tests/`:
+
+- Creating a payment succeeds and stores provider reference.
+- Creating with the same idempotency key returns the original record.
+- Webhook for `paid` updates status and timestamp.
+- Webhook with invalid signature is rejected.
+- Webhook is idempotent (replay does not change state or duplicate logs).
+
+Update `docs/risks.md` to mark payment integration gaps as addressed.
+
+## Concrete Steps
+
+Run these commands from the repository root (`/home/m7md/kshkool/Salon`).
+
+1. Inspect payments models and endpoints.
+    - Read `backend/apps/payments/models.py`, `backend/apps/payments/views.py`, and `backend/apps/payments/serializers.py`.
+
+2. Add fields for provider reference, status timestamps, and idempotency.
+    - Update `backend/apps/payments/models.py` and create a migration.
+    - Run:
+        python3 backend/manage.py makemigrations payments
+
+3. Implement services and endpoints.
+    - Add `backend/apps/payments/services.py`.
+    - Update serializers and views accordingly.
+
+4. Add webhook endpoint and signature verification.
+    - Update `backend/apps/payments/urls.py` and `backend/apps/payments/views.py`.
+
+5. Add tests.
+    - Create `backend/apps/payments/tests/test_payments_flow.py`.
+
+6. Run tests.
+    - Backend:
+        source venv/bin/activate
+        cd backend
+        python3 -m pytest
+
+## Validation and Acceptance
+
+- Creating a payment with a new idempotency key returns HTTP 201 and a provider reference.
+- Creating the same payment with the same idempotency key returns HTTP 200/201 with the original payment (no new provider request).
+- A valid webhook updates the payment status to `paid` and sets `paid_at`.
+- An invalid webhook signature returns HTTP 400/401 and does not mutate data.
+- `python3 -m pytest` passes with the new payments tests.
+
+## Idempotence and Recovery
+
+Payment creation is safe to retry with idempotency keys. Webhook processing is idempotent and can be replayed safely. If a payment status change is applied incorrectly, it can be corrected manually via admin and will be documented in audit fields.
+
+## Artifacts and Notes
+
+Example idempotency pattern:
+
+    existing = Payment.objects.filter(idempotency_key=key).first()
+    if existing:
+        return existing
+
+Example overlap-safe webhook logic:
+
+    if payment.status == PaymentStatus.PAID:
+        return
+    payment.mark_paid()
+
+## Interfaces and Dependencies
+
+- `backend/apps/payments/models.py` must include fields: `provider_reference`, `idempotency_key`, `status`, `initiated_at`, `paid_at`, `failed_at`, and (optionally) `provider_payload` (JSON).
+- `backend/apps/payments/services.py` must define `create_payment_for_booking(booking, idempotency_key, request_data)` and `verify_webhook_signature(request)`.
+- `backend/apps/payments/views.py` must expose `PaymentCreateAPIView` and `payment_webhook` with signature verification.
+
+Plan Maintenance Note: Created on 2026-02-28 to implement Moyasar payments with idempotency and webhook reconciliation as the next Phase 1 reliability milestone.
+Plan Maintenance Note (Update): Marked steps complete and recorded dependency and audit decisions after implementing payments and tests on 2026-02-28.

+# Payments Sanity Check (Moyasar Mock + Demo Data)
+
+This runbook documents the end-to-end sanity check for the Moyasar payments flow using demo data and a local mock provider. It is intended for developers and agents validating payment creation + webhook reconciliation before merging to `main`.
+
+## Purpose
+
+Verify that the payment creation endpoint and webhook processing work end-to-end in a local environment without hitting Moyasar.
+
+## Preconditions
+
+- Backend dependencies installed in the Python venv.
+- Frontend is not required for this check.
+- `backend/` database is migrated and uses SQLite for local dev.
+
+## High-level Flow
+
+1. Start a local mock Moyasar server (HTTP) that emulates `/v1/payments` responses.
+2. Run migrations and seed demo data.
+3. Start Django with a local payment configuration pointing to the mock server.
+4. Obtain a JWT access token for the demo customer.
+5. Create a payment for an existing booking.
+6. Send a webhook payload to mark it as paid.
+7. Verify the payment status updates.
+
+## Steps
+
+### 1) Start the mock Moyasar server
+
+The mock server responds to `POST /v1/payments` with a static `id` and `transaction_url`.
+
+Create the mock server at `/tmp/moyasar_mock.py` and run it:
+
+    python3 /tmp/moyasar_mock.py
+
+Expected: the process stays running, listening on `http://127.0.0.1:8001`.
+
+### 2) Run migrations and seed demo data
+
+    source venv/bin/activate
+    cd backend
+    python3 manage.py migrate
+    python3 manage.py seed_demo
+
+Expected: `Demo data seeded.`
+
+### 3) Start Django with the mock provider
+
+Run the backend with environment variables pointing to the mock server:
+
+    DJANGO_DEBUG=1 \
+    MOYASAR_SECRET_KEY=sk_test \
+    MOYASAR_PUBLISHABLE_KEY=pk_test \
+    MOYASAR_BASE_URL=http://127.0.0.1:8001 \
+    MOYASAR_WEBHOOK_SECRET=whsec \
+    python3 manage.py runserver 8000
+
+Expected: server starts at `http://127.0.0.1:8000/`.
+
+### 4) Obtain a JWT access token
+
+The demo customer is:
+
+- `customer@example.com`
+- `Customer123!`
+
+Fetch the access token:
+
+    curl -s -X POST http://127.0.0.1:8000/api/auth/token/ \
+      -H "Content-Type: application/json" \
+      -d '{"email":"customer@example.com","password":"Customer123!"}'
+
+Expected: JSON containing `access` and `refresh` tokens.
+
+### 5) Create a payment
+
+Pick a booking (demo data creates bookings; you can list them):
+
+    curl -s -H "Authorization: Bearer <ACCESS>" http://127.0.0.1:8000/api/bookings/
+
+Then create a payment (example uses booking id `3`):
+
+    curl -s -X POST http://127.0.0.1:8000/api/payments/ \
+      -H "Authorization: Bearer <ACCESS>" \
+      -H "Content-Type: application/json" \
+      -d '{
+            "booking_id": 3,
+            "provider": "moyasar",
+            "idempotency_key": "<UUID>",
+            "source": {"type": "stcpay", "mobile": "0500000000"}
+          }'
+
+Expected: response includes:
+
+- `status: initiated`
+- `external_id: pay_mock_123`
+- `redirect_url: https://moyasar.example/tx/mock`
+
+### 6) Send webhook for paid state
+
+    curl -s -X POST http://127.0.0.1:8000/api/payments/webhook/ \
+      -H "Content-Type: application/json" \
+      -d '{"type":"payment_paid","secret_token":"whsec","data":{"id":"pay_mock_123"}}'
+
+Expected: `{ "detail": "Webhook processed" }`
+
+### 7) Verify payment state
+
+    curl -s -H "Authorization: Bearer <ACCESS>" http://127.0.0.1:8000/api/payments/
+
+Expected: payment record shows:
+
+- `status: paid`
+- `paid_at` set
+- `metadata.last_webhook` populated
+
+## Considerations and Edge Cases
+
+- **Webhook secret**: `MOYASAR_WEBHOOK_SECRET` must be set. Requests missing or mismatching `secret_token` return `401`.
+- **Idempotency**: reuse the same `idempotency_key` to verify the API returns the existing payment without creating another provider charge.
+- **Unsupported sources**: `creditcard` is rejected by the backend. Use `stcpay`, `token`, or `applepay`.
+- **Callback URL**: required for `token` payments; otherwise validation fails.
+- **Demo data**: `seed_demo` creates a payment with `external_id=None` (not empty string) to avoid violating unique constraints.
+- **Debug mode**: `DJANGO_DEBUG=1` is required for local `runserver` if `ALLOWED_HOSTS` is not set.
+- **JWT warnings**: short JWT secret keys can trigger warnings in logs; this is acceptable for local sanity checks but should be hardened in production.
+
+## What to Look For
+
+- Payment creation returns `external_id` from the mock server.
+- Webhook transitions the payment to `paid` and populates `paid_at`.
+- `metadata.last_webhook` persists the payload for audit.
+
+## Cleanup
+
+- Stop the Django server (`Ctrl+C`).
+- Stop the mock server (`Ctrl+C`).
+- Optionally delete `/tmp/moyasar_mock.py`.
