Introduction

Welcome to the official documentation for the Marketplace API. This API allows developers to integrate with our platform to manage products, process orders, and interact with user data.

Our API follows RESTful principles and uses JSON for request and response bodies. All requests should be made over HTTPS.

Base URL: https://api.example.com/v1

Authentication

All requests to the Marketplace API require authentication. We use API keys for this purpose. Your API key should be included in the Authorization header of your requests as a Bearer token.

Authorization: Bearer YOUR_API_KEY

If you do not have an API key, please contact your account manager or visit the developer portal to generate one.

Example Request Header:

GET /v1/products HTTP/1.1
Host: api.example.com
Authorization: Bearer abcdef1234567890

The following are the primary API endpoints available:

Error Handling

The API uses standard HTTP status codes to indicate the success or failure of a request. Error responses will include a JSON body with more details.

Common Status Codes:

  • 200 OK: Request successful.
  • 201 Created: Resource successfully created.
  • 400 Bad Request: Invalid request payload or parameters.
  • 401 Unauthorized: Authentication credentials are missing or invalid.
  • 403 Forbidden: The authenticated user does not have permission.
  • 404 Not Found: The requested resource could not be found.
  • 500 Internal Server Error: An unexpected error occurred on the server.

Error Response Body Example:

{
  "error": {
    "code": "INVALID_PARAMETER",
    "message": "The 'price' field must be a positive number."
  }
}

Rate Limiting

To ensure fair usage and maintain performance, the API is subject to rate limiting. You will receive a 429 Too Many Requests status code if you exceed the limit.

The current rate limit is 100 requests per minute per API key.

Response headers will include:

  • X-RateLimit-Limit: The total number of requests allowed in the current window.
  • X-RateLimit-Remaining: The number of requests remaining in the current window.
  • X-RateLimit-Reset: The time (Unix timestamp) at which the limit will reset.
