What is the API Request Builder?

The API Request Builder helps you construct HTTP API requests with a visual interface. Configure the HTTP method, URL, headers, request body, and authentication (None, Bearer Token, Basic Auth). It generates the corresponding cURL command and code snippets that you can copy and use directly. Essential for API testing, documentation, and development without needing tools like Postman.
