API Invoker

About API Invoker

API Invoker is a simplified version of Postman that runs entirely in your browser. It allows you to test APIs by sending HTTP requests and viewing the responses without the need for a separate application.

Features:

• Multiple HTTP Methods: Support for GET, POST, PUT, DELETE, and PATCH requests.
• Request Configuration: Add query parameters, headers, and request bodies.
• Authentication: Basic Auth and Bearer Token support.
• Response Inspection: View response body and headers.
• Request History: Keep track of your previous API calls.
• Zero Setup: No installation or account creation required.

How to Use:

1. Enter the API endpoint URL in the URL field.
2. Select the appropriate HTTP method (GET, POST, etc.).
3. Configure your request with parameters, headers, body, or authentication as needed.
4. Click "Send" to make the request.
5. View the response in the Response panel.

Tips:

• Use the "Format JSON" button to pretty-print your JSON request body.
• The request history saves your previous calls for easy reference.
• Click on a history item to reload it into the request form.
• For secured APIs, use the Auth tab to add your credentials.

Upcoming Features:

• Curl Import: Paste curl commands to automatically populate request details.
• Environment Variables: Define and use variables in your requests.
• Response Visualization: Charts and graphs for response data.
• Request Collections: Save and organize your requests for future use.
