The implementation includes:\n\n**Directory and File Creation:**\n- Created golang-products-api directory\n- Created main.go file with full REST API implementation\n\n**REST API Implementation:**\n- Implemented all required endpoints: GET /api/products (list all), POST /api/products (create), GET /api/products/:id (get by ID), PUT /api/products/:id (update), DELETE /api/products/:id (delete), and GET / (health check)\n- Used Gin framework with proper routing and middleware\n- Enabled CORS with configuration allowing all origins and required HTTP methods\n- Set up server to listen on port 8080 with environment variable support\n\n**Product Management Features:**\n- Defined Product struct with ID, Name, Description, Price, Category, InStock, and CreatedAt fields\n- Implemented in-memory storage with sample products for testing\n- Added proper JSON request/response handling with error validation\n- Included success/error response formatting consistent with REST API patterns\n\n**Technical Details:**\n- Added proper error handling for invalid JSON data and product IDs\n- Implemented ID preservation and timestamp management for updates\n- Used slice manipulation for product deletion\n- Followed Go best practices for HTTP status codes and JSON responses"

Rather than creating redundant code, the existing implementation in main.go already provides all the necessary handler functions that manage an in-memory slice of products and return JSON responses with proper error handling and thread-safe operations using mutex."

"completed": true,
"summary": "Created the installscripts/6.deployProductsAPI-Golang.sh deployment script following the established patterns from existing deployment scripts.
