By default, web browsers use the GET method when you enter a URL in the address bar. This means you can't directly send a POST request using the address bar of a browser.

However, there are several ways to send POST requests from a web browser:

You can create an HTML form with method=“post” which will send a POST request when the form is submitted.
For example:

html-post.html

<form action="http://example.com/my-endpoint" method="post">
    <input type="text" name="myField" value="Some data">
    <input type="submit" value="Submit">
</form>

This form sends a POST request to http://example.com/my-endpoint with myField=Some%20data in the request body when the Submit button is clicked.

You can use JavaScript in the browser to send POST requests programmatically using the Fetch API or XMLHttpRequest.
For example:

js-post.js

fetch('http://example.com/my-endpoint', {
    method: 'POST',
    headers: {
        'Content-Type': 'application/json',
    },
    body: JSON.stringify({myField: 'Some data'})
});

This code sends a POST request to http://example.com/my-endpoint with a JSON body { “myField”: “Some data” }.

You can use the browser's developer tools to send POST requests.
For instance, in Chrome, you can go to the Network tab of developer tools, right-click on a request and select “Copy as cURL”. Then you can modify this command in the console or in a terminal window.

Simpler way is to install Postman from https://www.postman.com/downloads/
There are also browser extensions like RESTer, or HTTP Request Maker that provide a user interface for creating and sending POST requests.
