🔌 Retailer API Integrations

Manage connections to multiple retailer APIs. Search products, check availability, and compare prices across all integrated retailers simultaneously.

How It Works

🏗️

Standardized Framework

Every retailer uses the same integration interface. Add new retailers without modifying existing code.

📊

Data Normalization

All APIs return consistent product data format. Compare prices and specs across different retailers easily.

⚡

Smart Rate Limiting

Respects each API's rate limits automatically. Queues requests and applies backoff when needed.

🔄

Automatic Retry Logic

Handles transient failures gracefully. Implements exponential backoff and intelligent retry strategies.

Supported Features

Product Search

Search across multiple retailers simultaneously with keyword, category, and price filters.

Availability Checking

Check stock levels and availability across all retailers for a specific product.

Price Comparison

View prices, discounts, and original prices for the same product across retailers.

Product Details

Get detailed information including ratings, reviews, images, and specifications.

API Type Support

REST, GraphQL, RSS feeds, and web scraping. Mix and match API types for different retailers.

Architecture

RetailerAdapter (Abstract Base)

├─ validate(): Verify config
├─ searchProducts(params): Search
├─ getProductDetails(id): Get details
├─ checkAvailability(id): Check stock
└─ normalize(data): Standardize output

Concrete Implementations

├─ RESTRetailerAdapter (JSON APIs)
├─ GraphQLRetailerAdapter (GraphQL endpoints)
├─ RSSRetailerAdapter (Feed parsers)
└─ ScraperRetailerAdapter (Web scraping)

RetailerIntegrationFramework

├─ registerAdapter(config): Register new retailer
├─ searchAllRetailers(params): Multi-retailer search
├─ getProductDetails(retailerId, id): Single retailer
└─ checkAvailabilityAllRetailers(id): Stock across all

Cross-Cutting Concerns

├─ Rate Limiting: Per-retailer quotas
├─ Error Handling: IntegrationError codes
├─ Retry Logic: Exponential backoff
├─ Auth: API key management
└─ Security: No credential leaks

Adding a New Retailer

Step 1: Create Adapter

Extend RetailerAdapter or use RESTRetailerAdapter if API is JSON-based.

Step 2: Implement Methods

Implement searchProducts, getProductDetails, and checkAvailability matching API.

Step 3: Register Config

Add RetailerConfig with API details (base URL, keys, rate limits, categories).

Step 4: Register Adapter

Call framework.registerAdapter(config, AdapterClass) and that's it!
