The Product Catalog API empowers you to programmatically interact with your product inventory. Whether you're building an e-commerce platform, an inventory management system, or a mobile application, our API provides the tools necessary to perform CRUD (Create, Read, Update, Delete) operations on your product data. Key features include:
To get started, you'll need an API Key. Once you have your key, you can make your first API call. Here's a quick example to retrieve a list of all products:
Replace `YOUR_API_KEY` with your actual API key. A successful response will return a JSON array of product objects. --- ### Authentication All requests to the Product Catalog API must be authenticated using an API Key. We use a Bearer Token scheme for authentication. **How to Authenticate:** Include your API Key in the `Authorization` header of every request, prefixed with `Bearer`. **Header Example:** `Authorization: Bearer YOUR_API_KEY` **Obtaining Your API Key:** Your API Key can be generated and managed from your developer dashboard. If you do not have one, please register an account or contact support. **Security Best Practices:** * Keep your API Key confidential. Do not expose it in client-side code or public repositories. * Rotate your API Keys periodically for enhanced security. * Use HTTPS for all API calls to ensure encrypted communication. --- ### Base URL The base URL for all API requests is: `https://api.yourdomain.com/v1` All endpoint paths listed in this documentation are relative to this base URL. --- ### Error Handling Our API uses standard HTTP status codes to indicate the success or failure of an API request. In cases of failure, the API will return a JSON object containing specific error details to help you diagnose and resolve issues. **Common HTTP Status Codes:** * **`200 OK`**: The request was successful (e.g., GET, PUT, DELETE). * **`201 Created`**: The request resulted in a new resource being created (e.g., POST). * **`204 No Content`**: The request was successful, but there is no content to return (e.g., successful DELETE). * **`400 Bad Request`**: The request was malformed or invalid. * **`401 Unauthorized`**: Authentication is required or has failed. * **`403 Forbidden`**: The authenticated user does not have the necessary permissions. * **`404 Not Found`**: The requested resource could not be found. * **`405 Method Not Allowed`**: The HTTP method used is not supported for the requested resource. * **`429 Too Many Requests`**: Rate limiting has been applied. * **`500 Internal Server Error`**: An unexpected error occurred on the server. **Error Response Example:**

This document provides a comprehensive guide to integrating with the Product Management System API. It details authentication methods, available endpoints, request/response structures, and error handling, enabling developers to seamlessly interact with and manage product data programmatically.
The Product Management System API allows developers to programmatically manage products, including creation, retrieval, updates, and deletion. This API is designed for building applications that integrate with product catalogs, inventory systems, e-commerce platforms, or any system requiring robust product data management.
Key Features:
To begin using the Product Management System API, follow these quick steps:
The Product Management System API uses API Key authentication. You must include your API Key in the X-API-Key header for every request. Failure to provide a valid API Key will result in a 401 Unauthorized error.
Header Name: X-API-Key
Example:
X-API-Key: YOUR_API_KEY_HERE
Example Request with Authentication:
curl -X GET \
'https://api.example.com/v1/products' \
-H 'Accept: application/json' \
-H 'X-API-Key: YOUR_API_KEY_HERE'
All requests to the Product Management System API should use the following base URL:
https://api.example.com/v1
The API exclusively uses JSON for both request bodies and response payloads.
Content-Type: application/jsonAccept: application/jsonTo ensure fair usage and system stability, the API imposes rate limits.
429 Too Many Requests status code. * X-RateLimit-Limit: The maximum number of requests you can make in the current window.
* X-RateLimit-Remaining: The number of requests remaining in the current window.
* X-RateLimit-Reset: The UTC epoch timestamp when the current rate limit window resets.
The API uses standard HTTP status codes to indicate the success or failure of an API request. In case of an error, the API will return a JSON object containing an error field with a descriptive message.
| HTTP Status Code | Description | Example Error Response |
| :--------------- | :------------------------------------------- | :------------------------------------------------------------ |
| 200 OK | Request successful. | N/A |
| 201 Created | Resource successfully created. | N/A |
| 204 No Content | Request successful, no content to return. | N/A |
| 400 Bad Request| Invalid request payload or parameters. | { "error": "Invalid product data provided." } |
| 401 Unauthorized| Missing or invalid API Key. | { "error": "Authentication required." } |
| 403 Forbidden | API Key lacks necessary permissions. | { "error": "Access denied." } |
| 404 Not Found | Resource does not exist. | { "error": "Product not found." } |
| 405 Method Not Allowed| HTTP method not supported for this endpoint. | { "error": "Method not allowed for this resource." } |
| 409 Conflict | Resource already exists or a conflict occurred. | { "error": "Product SKU already exists." } |
| 422 Unprocessable Entity| Semantic errors in the request body. | { "error": "Validation failed: 'name' is required." } |
| 429 Too Many Requests| Rate limit exceeded. | { "error": "Rate limit exceeded. Please try again later." } |
| 500 Internal Server Error| An unexpected server error occurred. | { "error": "An unexpected error occurred." } |
This section details all available API endpoints, their methods, parameters, and example requests/responses.
