API Documentation: PantheraHive User Management API (v1)

This document provides comprehensive technical documentation for the PantheraHive User Management API, version 1. It details how to authenticate, interact with various endpoints, understand request/response structures, and handle potential errors. This API allows developers to programmatically manage user accounts within the PantheraHive ecosystem.

1. Introduction

The PantheraHive User Management API provides a robust and secure way to integrate user creation, retrieval, update, and deletion functionalities into your applications. It adheres to RESTful principles, uses standard HTTP methods, and communicates via JSON payloads.

Key Features:

• Secure authentication using API Keys.
• Standard HTTP status codes for clear communication.
• JSON-based request and response bodies.
• Rate limiting to ensure fair usage and system stability.

2. Base URL

All API requests should be made to the following base URL:

https://api.pantherahive.com/v1

3. Authentication

The PantheraHive User Management API uses API Key authentication. To authenticate your requests, you must include your unique API Key in the Authorization header of every request, prefixed with Bearer.

Header Example:

Authorization: Bearer YOUR_API_KEY

How to obtain your API Key:

1. Log in to your PantheraHive developer dashboard.
2. Navigate to the "API Keys" section.
3. Generate a new API Key if you don't have one, or use an existing one.

Important Security Notes:

• Keep your API Key confidential. Do not expose it in client-side code, public repositories, or unsecured environments.
• Regenerate your API Key immediately if you suspect it has been compromised.

4. Error Handling

The API uses standard HTTP status codes to indicate the success or failure of an API request. In cases of errors, the API will return a JSON object containing details about the error.

Common HTTP Status Codes:

| Status Code | Description |

| :---------- | :-------------------------------------------- |

| 200 OK | The request was successful. |

| 201 Created | The request was successful, and a new resource was created. |

| 204 No Content | The request was successful, but there is no content to return (e.g., successful deletion). |

| 400 Bad Request | The request was malformed or invalid. Check your request body or parameters. |

| 401 Unauthorized | Authentication failed. Missing or invalid API Key. |

| 403 Forbidden | You do not have permission to access the requested resource or perform the action. |

| 404 Not Found | The requested resource could not be found. |

| 409 Conflict | The request could not be completed due to a conflict (e.g., attempting to create a user with an existing email). |

| 429 Too Many Requests | You have exceeded the API rate limit. Try again after the specified Retry-After time. |

| 500 Internal Server Error | An unexpected error occurred on the server. Please report this to support. |

Error Response Structure Example:

{
  "code": "invalid_parameter",
  "message": "The 'email' field is required.",
  "details": [
    {
      "field": "email",
      "issue": "must not be blank"
    }
  ]
}

5. Rate Limiting

To ensure stability and fair usage, the PantheraHive User Management API implements rate limiting.

• Limit: 100 requests per minute per API Key.
• Headers:

* X-RateLimit-Limit: The maximum number of requests you can make in the current period.

* X-RateLimit-Remaining: The number of requests remaining in the current period.

* X-RateLimit-Reset: The UTC epoch seconds when the current rate limit window resets.

• Exceeding the Limit: If you exceed the rate limit, the API will return a 429 Too Many Requests status code. The response will include a Retry-After header indicating how many seconds you should wait before making another request.
