Getting Started

API Test Hub is a browser-based tool designed to simplify API testing. To begin, navigate to the main interface and enter your API endpoint URL in the provided input field.

• Enter a valid URL (e.g., https://api.example.com/endpoint).
• Select an HTTP method (GET, POST, PUT, etc.) from the dropdown.
• Configure query parameters, headers, or a JSON body as needed.
• Click "Send Request" to execute the API call.

Sending Requests

API Test Hub supports multiple HTTP methods and allows you to customize your requests extensively.

Query Parameters

Add key-value pairs for query parameters under the "Query Parameters" tab. These will be appended to the URL automatically.

Headers

Add custom headers (e.g., Authorization, Content-Type) in the "Headers" tab. Use the "+" button to add more headers.

Request Body

For POST, PUT, or PATCH requests, enter a JSON body in the "Body" tab. Syntax highlighting helps ensure valid JSON format.

Environment Variables

Use environment variables to manage dynamic values like API keys or base URLs. Define them in the "Environment Variables" section and reference them in the URL using {{key}} syntax.

Example: Set baseUrl to https://api.example.com, then use https://{{baseUrl}}/endpoint in the URL field.

Request History

Every request is saved locally in your browser. Access past requests via the "Show History" button, load them to reuse, or export them as a JSON file for sharing.

• Click a history item to load its details into the form.
• Use "Export History" to save requests as a JSON file.
• Use "Import History" to load a previously exported JSON file.

Troubleshooting

If you encounter issues, check the following:

• Ensure the URL is valid and accessible.
• Verify JSON body syntax in the "Body" tab.
• Check if headers like Content-Type: application/json are set correctly.
• Adjust the timeout (default: 30s) for slow APIs.
