WooNooW API Routes Standard

Namespace

All routes use: woonoow/v1

Route Naming Convention

Pattern

/{resource}                    # List/Create
/{resource}/{id}               # Get/Update/Delete single item
/{resource}/{action}           # Special actions
/{resource}/{id}/{sub}         # Sub-resources

Rules

  1. Use plural nouns for resources (/products, /orders, /customers)
  2. Use kebab-case for multi-word resources (/pickup-locations)
  3. Use specific action names to avoid conflicts (/products/search, /orders/preview)
  4. Never create generic routes that might conflict (/products vs /products)
  5. Never use verbs as resource names (/get-products , use /products )

Current Routes Registry

Products Module (ProductsController.php)

GET    /products                    # List products (admin)
GET    /products/{id}               # Get single product
POST   /products                    # Create product
PUT    /products/{id}               # Update product
DELETE /products/{id}               # Delete product
GET    /products/categories         # List categories
POST   /products/categories         # Create category
GET    /products/tags               # List tags
POST   /products/tags               # Create tag
GET    /products/attributes         # List attributes

Orders Module (OrdersController.php)

GET    /orders                      # List orders
GET    /orders/{id}                 # Get single order
POST   /orders                      # Create order
PUT    /orders/{id}                 # Update order
DELETE /orders/{id}                 # Delete order
POST   /orders/preview              # Preview order totals
GET    /products/search             # Search products for order form (⚠️ Special route)
GET    /customers/search            # Search customers for order form (⚠️ Special route)

⚠️ Important:

  • /products/search is owned by OrdersController (NOT ProductsController)
  • This is for lightweight product search in order forms
  • ProductsController owns /products for full product management

Customers Module (CustomersController.php - Future)

GET    /customers                   # List customers
GET    /customers/{id}              # Get single customer
POST   /customers                   # Create customer
PUT    /customers/{id}              # Update customer
DELETE /customers/{id}              # Delete customer

⚠️ Important:

  • /customers/search is already used by OrdersController
  • CustomersController will own /customers for full customer management
  • No conflict because routes are specific

Coupons Module (CouponsController.php) IMPLEMENTED

GET    /coupons                     # List coupons (with pagination, search, filter)
GET    /coupons/{id}                # Get single coupon
POST   /coupons                     # Create coupon
PUT    /coupons/{id}                # Update coupon
DELETE /coupons/{id}                # Delete coupon
POST   /coupons/validate            # Validate coupon code (OrdersController)

Implementation Details:

  • List: Supports pagination (page, per_page), search (search), filter by type (discount_type)
  • Create: Validates code uniqueness, requires code, amount, discount_type
  • Update: Full coupon data update, code cannot be changed after creation
  • Delete: Supports force delete via query param
  • Validate: Handled by OrdersController for order context

Note:

  • /coupons/validate is in OrdersController (order-specific validation)
  • CouponsController owns /coupons for coupon CRUD management
  • No conflict because validate is a specific action route

Settings Module (SettingsController.php)

GET    /settings                    # Get all settings
PUT    /settings                    # Update settings
GET    /settings/store              # Get store settings
GET    /settings/tax                # Get tax settings
GET    /settings/shipping           # Get shipping settings
GET    /settings/payments           # Get payment settings

Analytics Module (AnalyticsController.php)

GET    /analytics/overview          # Dashboard overview
GET    /analytics/products          # Product analytics
GET    /analytics/orders            # Order analytics
GET    /analytics/customers         # Customer analytics

Conflict Prevention Rules

1. Resource Ownership

Each resource has ONE primary controller:

  • /productsProductsController
  • /ordersOrdersController
  • /customersCustomersController (future)
  • /couponsCouponsController (future)

2. Cross-Resource Operations

When one module needs data from another resource, use specific action routes:

Good:

// OrdersController needs product search
register_rest_route('woonoow/v1', '/products/search', [...]);

// OrdersController needs customer search
register_rest_route('woonoow/v1', '/customers/search', [...]);

// OrdersController needs coupon validation
register_rest_route('woonoow/v1', '/orders/validate-coupon', [...]);

Bad:

// OrdersController trying to own /products
register_rest_route('woonoow/v1', '/products', [...]);  // CONFLICT!

// OrdersController trying to own /customers
register_rest_route('woonoow/v1', '/customers', [...]);  // CONFLICT!

3. Sub-Resource Pattern

Use sub-resources for related data:

Good:

// Order-specific coupons
GET /orders/{id}/coupons           # List coupons applied to order
POST /orders/{id}/coupons          # Apply coupon to order
DELETE /orders/{id}/coupons/{code} # Remove coupon from order

// Order-specific notes
GET /orders/{id}/notes             # List order notes
POST /orders/{id}/notes            # Add order note

4. Action Routes

Use descriptive action names to avoid conflicts:

Good:

POST /orders/preview               # Preview order totals
POST /orders/calculate-shipping    # Calculate shipping
GET /products/search               # Search products (lightweight)
GET /coupons/validate              # Validate coupon code

Bad:

POST /orders/calc                  # Too vague
GET /search                        # Too generic
GET /validate                      # Too generic

Registration Order

WordPress REST API uses first-registered-wins for route conflicts.

Controller Registration Order (in Routes.php):

1. SettingsController
2. ProductsController      # Registers /products first
3. OrdersController        # Can use /products/search (no conflict)
4. CustomersController     # Will register /customers
5. CouponsController       # Will register /coupons
6. AnalyticsController

⚠️ Critical:

  • ProductsController MUST register before OrdersController
  • This ensures /products is owned by ProductsController
  • OrdersController can safely use /products/search (different path)

Testing for Conflicts

1. Check Route Registration

// Add to Routes.php temporarily
add_action('rest_api_init', function() {
    $routes = rest_get_server()->get_routes();
    error_log('WooNooW Routes: ' . print_r($routes['woonoow/v1'], true));
}, 999);

2. Test API Endpoints

# Test product list (should hit ProductsController)
curl -X GET "https://site.local/wp-json/woonoow/v1/products"

# Test product search (should hit OrdersController)
curl -X GET "https://site.local/wp-json/woonoow/v1/products/search?s=test"

# Test customer search (should hit OrdersController)
curl -X GET "https://site.local/wp-json/woonoow/v1/customers/search?s=john"

3. Frontend API Calls

// ProductsApi - Full product management
ProductsApi.list()           GET /products
ProductsApi.get(id)          GET /products/{id}
ProductsApi.create(data)     POST /products

// OrdersApi - Product search for orders
ProductsApi.search(query)    GET /products/search

// CustomersApi - Customer search for orders
CustomersApi.search(query)   GET /customers/search

Future Considerations

When Adding New Modules:

  1. Check existing routes - Review this document
  2. Choose specific names - Avoid generic routes
  3. Use sub-resources - For related data
  4. Update this document - Add new routes to registry
  5. Test for conflicts - Use testing methods above

Reserved Routes (Do Not Use):

/products          # ProductsController
/orders            # OrdersController
/customers         # CustomersController (future)
/coupons           # CouponsController (future)
/settings          # SettingsController
/analytics         # AnalyticsController

Safe Action Routes:

/products/search   # OrdersController (lightweight search)
/customers/search  # OrdersController (lightweight search)
/orders/preview    # OrdersController (order preview)
/coupons/validate  # CouponsController (coupon validation)

Summary

Do:

  • Use plural nouns for resources
  • Use specific action names
  • Use sub-resources for related data
  • Register controllers in correct order
  • Update this document when adding routes

Don't:

  • Create generic routes that might conflict
  • Use verbs as resource names
  • Register same route in multiple controllers
  • Forget to test for conflicts

Remember: First-registered-wins! Always check existing routes before adding new ones.
