About API Tester
Our API Tester tool helps developers test and debug APIs without writing code. It provides a simple interface for sending HTTP requests and examining responses, making it easier to work with RESTful APIs and web services.
APIs (Application Programming Interfaces) are sets of rules that allow different software applications to communicate with each other. Testing APIs is an essential part of development to ensure they work as expected and handle various scenarios correctly.
With our tool, you can:
- Send requests using different HTTP methods (GET, POST, PUT, DELETE, etc.)
- Add custom headers to your requests
- Include query parameters in your URLs
- Send request bodies for methods that support them
- View response status, headers, and body
- Copy and download response data
