Features
❤️ Lightweight: Crafted with minimalistic UI design.
⚡️ Fast: Send requests and get responses in real time.
🗄️ HTTP Methods: Request methods define the type of action you are requesting to be performed.

GET - Requests retrieve resource information
POST - The server creates a new entry in a database
PUT - Updates an existing resource
PATCH - Very similar to PUT but makes a partial update on a resource
DELETE - Deletes resource or related component
HEAD - Retrieve response headers identical to those of a GET request, but without the response body.
CONNECT - Establishes a tunnel to the server identified by the target resource
OPTIONS - Describe the communication options for the target resource
TRACE - Performs a message loop-back test along the path to the target resource
<custom> - Some APIs use custom request methods such as LIST. Type in your custom methods.
