# Store-in-Token Architecture
## Overview
This document describes the store-in-token authentication architecture used for store API endpoints. This architecture embeds store context directly into JWT tokens, eliminating the need for URL-based store detection and enabling clean, RESTful API endpoints.
## The Problem: URL-Based Store Detection
### Old Pattern (Deprecated)
```python
# ❌ DEPRECATED: URL-based store detection
@router.get("/{product_id}")
def get_product(
product_id: int,
store: Store = Depends(require_store_context()), # ❌ Don't use
current_user: User = Depends(get_current_store_api),
db: Session = Depends(get_db),
):
product = product_service.get_product(db, store.id, product_id)
return product
```
### Issues with URL-Based Detection
1. **Inconsistent API Routes**
- Page routes: `/store/{store_code}/dashboard` (has store in URL)
- API routes: `/api/v1/store/products` (no store in URL)
- `require_store_context()` only works when store is in the URL path
2. **404 Errors on API Endpoints**
- API calls to `/api/v1/store/products` would return 404
- The dependency expected store code in URL but API routes don't have it
- Breaking RESTful API design principles
3. **Architecture Violation**
- Mixed concerns: URL structure determining business logic
- Tight coupling between routing and store context
- Harder to test and maintain
## The Solution: Store-in-Token
### Architecture Overview

└─────────────────────────────────────────────────────────────────┘
```
### Implementation Components
#### 1. Token Creation (middleware/auth.py)
```python
def create_access_token(
self,
user: User,
store_id: int | None = None,
store_code: str | None = None,
store_role: str | None = None,
) -> dict[str, Any]:
"""Create JWT with optional store context."""
payload = {
"sub": str(user.id),
"username": user.username,
"email": user.email,
"role": user.role,
"exp": expire,
"iat": datetime.now(UTC),
}
# Include store information in token if provided
if store_id is not None:
payload["store_id"] = store_id
if store_code is not None:
payload["store_code"] = store_code
if store_role is not None:
payload["store_role"] = store_role
return {
"access_token": jwt.encode(payload, self.secret_key, algorithm=self.algorithm),
"token_type": "bearer",
"expires_in": self.access_token_expire_minutes * 60,
}
```
#### 2. Store Login (app/api/v1/store/auth.py)
```python
@router.post("/login", response_model=StoreLoginResponse)
def store_login(
user_credentials: UserLogin,
response: Response,
db: Session = Depends(get_db),
):
"""
Store team member login.
Creates store-scoped JWT token with store context embedded.
"""
# Authenticate user and determine store
login_result = auth_service.login_user(db=db, user_credentials=user_credentials)
user = login_result["user"]
# Determine store and role
store = determine_store(db, user) # Your store detection logic
store_role = determine_role(db, user, store) # Your role detection logic
# Create store-scoped access token
token_data = auth_service.auth_manager.create_access_token(
user=user,
store_id=store.id,
store_code=store.store_code,
store_role=store_role,
)
# Set cookie and return token
response.set_cookie(
key="store_token",
value=token_data["access_token"],
httponly=True,
path="/store", # Restricted to store routes
)
return StoreLoginResponse(**token_data, user=user, store=store)
```
#### 3. Token Verification (app/api/deps.py)
```python
def get_current_store_api(
authorization: str | None = Header(None, alias="Authorization"),
db: Session = Depends(get_db),
) -> User:
"""
Get current store API user from Authorization header.
Extracts store context from JWT token and validates access.
"""
if not authorization or not authorization.startswith("Bearer "):
raise AuthenticationException("Authorization header required for API calls")
token = authorization.replace("Bearer ", "")
user = auth_service.auth_manager.get_current_user(token, db)
# Validate store access if token is store-scoped
if hasattr(user, "token_store_id"):
store_id = user.token_store_id
# Verify user still has access to this store
if not user.is_member_of(store_id):
raise InsufficientPermissionsException(
"Access to store has been revoked. Please login again."
)
return user
```
#### 4. Endpoint Usage (app/api/v1/store/products.py)
```python
@router.get("", response_model=ProductListResponse)
def get_store_products(
skip: int = Query(0, ge=0),
limit: int = Query(100, ge=1, le=1000),
current_user: User = Depends(get_current_store_api), # ✅ Guarantees token_store_id
db: Session = Depends(get_db),
):
"""
Get all products in store catalog.
Store is determined from JWT token (store_id claim).
The get_current_store_api dependency GUARANTEES token_store_id is present.
"""
# Use store_id from token for business logic
# NO validation needed - dependency guarantees token_store_id exists
products, total = product_service.get_store_products(
db=db,
store_id=current_user.token_store_id, # Safe to use directly
skip=skip,
limit=limit,
)
return ProductListResponse(products=products, total=total)
```
> **IMPORTANT**: The `get_current_store_api()` dependency now **guarantees** that `token_store_id` is present.
> Endpoints should NOT check for its existence - this would be redundant validation that belongs in the dependency layer.
## Migration Guide
### Step 1: Identify Endpoints Using require_store_context()
Search for all occurrences:
```bash
grep -r "require_store_context" app/api/v1/store/
```
### Step 2: Update Endpoint Signature
**Before:**
```python
@router.get("/{product_id}")
def get_product(
product_id: int,
store: Store = Depends(require_store_context()), # ❌ Remove this
current_user: User = Depends(get_current_store_api),
db: Session = Depends(get_db),
):
```
**After:**
```python
@router.get("/{product_id}")
def get_product(
product_id: int,
current_user: User = Depends(get_current_store_api), # ✅ Only need this
db: Session = Depends(get_db),
):
```
### Step 3: Extract Store from Token
**Before:**
```python
product = product_service.get_product(db, store.id, product_id)
```
**After:**
```python
# Use store_id from token directly - dependency guarantees it exists
product = product_service.get_product(db, current_user.token_store_id, product_id)
```
> **NOTE**: Do NOT add validation like `if not hasattr(current_user, "token_store_id")`.
> The `get_current_store_api` dependency guarantees this attribute is present.
> Adding such checks violates the architecture rule API-003 (endpoints should not raise exceptions).
### Step 4: Update Logging References
**Before:**
```python
logger.info(f"Product updated for store {store.store_code}")
```
**After:**
```python
logger.info(f"Product updated for store {current_user.token_store_code}")
```
### Complete Migration Example
**Before (URL-based store detection):**
```python
@router.put("/{product_id}", response_model=ProductResponse)
def update_product(
product_id: int,
product_data: ProductUpdate,
store: Store = Depends(require_store_context()), # ❌
current_user: User = Depends(get_current_store_api),
db: Session = Depends(get_db),
):
"""Update product in store catalog."""
product = product_service.update_product(
db=db,
store_id=store.id, # ❌ From URL
product_id=product_id,
product_update=product_data
)
logger.info(
f"Product {product_id} updated by {current_user.username} "
f"for store {store.store_code}" # ❌ From URL
)
return ProductResponse.model_validate(product)
```
**After (Token-based store context):**
```python
@router.put("/{product_id}", response_model=ProductResponse)
def update_product(
product_id: int,
product_data: ProductUpdate,
current_user: User = Depends(get_current_store_api), # ✅ Guarantees token_store_id
db: Session = Depends(get_db),
):
"""Update product in store catalog."""
# NO validation needed - dependency guarantees token_store_id exists
product = product_service.update_product(
db=db,
store_id=current_user.token_store_id, # ✅ From token - safe to use directly
product_id=product_id,
product_update=product_data
)
logger.info(
f"Product {product_id} updated by {current_user.username} "
f"for store {current_user.token_store_code}" # ✅ From token
)
return ProductResponse.model_validate(product)
```
> **Architecture Rule API-003**: Endpoints should NOT raise exceptions. The `get_current_store_api` dependency
> handles all validation and raises `InvalidTokenException` if `token_store_id` is missing.
## Migration Status
**COMPLETED** - All store API endpoints have been migrated to use the token-based store context pattern.
### Migrated Files
All store API files now use `current_user.token_store_id`:
- `app/api/v1/store/customers.py` ✅
- `app/api/v1/store/notifications.py` ✅
- `app/api/v1/store/media.py` ✅
- `app/api/v1/store/marketplace.py` ✅
- `app/api/v1/store/inventory.py` ✅
- `app/api/v1/store/settings.py` ✅
- `app/api/v1/store/analytics.py` ✅
- `app/api/v1/store/payments.py` ✅
- `app/api/v1/store/profile.py` ✅
- `app/api/v1/store/dashboard.py` ✅
- `app/api/v1/store/products.py` ✅
- `app/api/v1/store/orders.py` ✅
- `app/api/v1/store/team.py` ✅ (uses permission dependencies)
### Permission Dependencies Updated
The following permission dependencies now use token-based store context:
- `require_store_permission()` - Gets store from token, sets `request.state.store`
- `require_store_owner` - Gets store from token, sets `request.state.store`
- `require_any_store_permission()` - Gets store from token, sets `request.state.store`
- `require_all_store_permissions()` - Gets store from token, sets `request.state.store`
- `get_user_permissions` - Gets store from token, sets `request.state.store`
### Shop Endpoints
Shop endpoints (public, no authentication) still use `require_store_context()`:
- `app/api/v1/shop/products.py` - Uses URL/subdomain/domain detection
- `app/api/v1/shop/cart.py` - Uses URL/subdomain/domain detection
This is correct behavior - shop endpoints need to detect store from the request URL, not from JWT token.
## Benefits of Store-in-Token
### 1. Clean RESTful APIs
```
✅ /api/v1/store/products
✅ /api/v1/store/orders
✅ /api/v1/store/customers
❌ /api/v1/store/{store_code}/products (unnecessary store in URL)
```
### 2. Security
- Store context cryptographically signed in JWT
- Cannot be tampered with by client
- Automatic validation on every request
- Token revocation possible via database checks
### 3. Consistency
- Same authentication mechanism for all store API endpoints
- No confusion between page routes and API routes
- Single source of truth (the token)
### 4. Performance
- No database lookup for store context on every request
- Store information already in token payload
- Optional validation for revoked access
### 5. Maintainability
- Simpler endpoint signatures
- Less boilerplate code
- Easier to test
- Follows architecture rule API-002 (no DB queries in endpoints)
## Security Considerations
### Token Validation
The token store context is validated on every request:
1. JWT signature verification (ensures token not tampered with)
2. Token expiration check (typically 30 minutes)
3. Optional: Verify user still member of store (database check)
### Access Revocation
If a user's store access is revoked:
1. Existing tokens remain valid until expiration
2. `get_current_store_api()` performs optional database check
3. User forced to re-login after token expires
4. New login will fail if access revoked
### Token Refresh
Tokens should be refreshed periodically:
- Default: 30 minutes expiration
- Refresh before expiration for seamless UX
- New login creates new token with current store membership
## Testing
### Unit Tests
```python
def test_store_in_token():
"""Test store context in JWT token."""
# Create token with store context
token_data = auth_manager.create_access_token(
user=user,
store_id=123,
store_code="WIZAMART",
store_role="Owner",
)
# Verify token contains store data
payload = jwt.decode(token_data["access_token"], secret_key)
assert payload["store_id"] == 123
assert payload["store_code"] == "WIZAMART"
assert payload["store_role"] == "Owner"
def test_api_endpoint_uses_token_store():
"""Test API endpoint extracts store from token."""
response = client.get(
"/api/v1/store/products",
headers={"Authorization": f"Bearer {token}"}
)
assert response.status_code == 200
# Verify products are filtered by token store_id
```
### Integration Tests
```python
def test_store_login_and_api_access():
"""Test full store login and API access flow."""
# Login as store user
response = client.post("/api/v1/store/auth/login", json={
"username": "john.doe",
"password": "password123"
})
assert response.status_code == 200
token = response.json()["access_token"]
# Access store API with token
response = client.get(
"/api/v1/store/products",
headers={"Authorization": f"Bearer {token}"}
)
assert response.status_code == 200
# Verify store context from token
products = response.json()["products"]
# All products should belong to token store
```
## Architecture Rules and Design Pattern Enforcement
### The Layered Exception Pattern
The architecture enforces a strict layered pattern for where exceptions should be raised:
```
┌────────────────────────────────────────────────────────────────────────────┐
│ ENDPOINTS (Thin Layer) - app/api/v1/**/*.py │
│ │
│ ❌ MUST NOT raise exceptions │
│ ❌ MUST NOT check hasattr(current_user, 'token_store_id') │
│ ✅ MUST trust dependencies to handle validation │
│ ✅ MUST directly use current_user.token_store_id │
└────────────────────────────────────────────────────────────────────────────┘
│
▼
┌────────────────────────────────────────────────────────────────────────────┐
│ DEPENDENCIES (Validation Layer) - app/api/deps.py │
│ │
│ ✅ MUST raise InvalidTokenException if token_store_id missing │
│ ✅ MUST validate user still has store access │
│ ✅ GUARANTEES token_store_id, token_store_code, token_store_role │
└────────────────────────────────────────────────────────────────────────────┘
│
▼
┌────────────────────────────────────────────────────────────────────────────┐
│ SERVICES (Business Logic) - app/services/**/*.py │
│ │
│ ✅ MUST raise domain exceptions for business rule violations │
│ ✅ Examples: StoreNotFoundException, ProductNotFoundException │
└────────────────────────────────────────────────────────────────────────────┘
│
▼
┌────────────────────────────────────────────────────────────────────────────┐
│ GLOBAL EXCEPTION HANDLER - app/exceptions/handler.py │
│ │
│ ✅ Catches all WizamartException subclasses │
│ ✅ Converts to appropriate HTTP responses │
│ ✅ Provides consistent error formatting │
└────────────────────────────────────────────────────────────────────────────┘
```
### Enforced by Architecture Validation
The validation script (`scripts/validate_architecture.py`) enforces these rules:
**Rule API-003: Endpoints must NOT raise exceptions directly**
- Detects `raise HTTPException`, `raise InvalidTokenException`, etc. in endpoint files
- Detects redundant validation like `if not hasattr(current_user, 'token_store_id')`
- Blocks commits via pre-commit hook if violations found
### Pre-commit Hook
Architecture validation runs on every commit:
```yaml
# .pre-commit-config.yaml
- repo: local
hooks:
- id: validate-architecture
name: Validate Architecture Patterns
entry: python scripts/validate_architecture.py
language: python
pass_filenames: false
always_run: true
```
To run manually:
```bash
python scripts/validate_architecture.py # Full validation
python scripts/validate_architecture.py -d app/api/v1/store/ # Specific directory
```
See `.architecture-rules.yaml` for the complete rule definitions.
