How to create a HTTP API

Hello!

In this post I found out, that it’s possible to send data to another server/domain with WP HTTP API.

I know already, how to build a post request. So on click a button at server1 it should send the userdata to server2:

  
//POST-REQUEST at server1/domain1
  $body = array(
      'username' => 'Bob',
      'email' => '[email protected]'
  );

  $args = array(
      'body' => $body,
      'method' => 'POST',
      'timeout' => '45',
      'redirection' => '5',
      'httpversion' => '1.0',
      'blocking' => true,
      'headers' => array(),
      'cookies' => array()
  );

    $response = wp_remote_post( $url, $args );

    if ( is_wp_error( $response ) ) {
        $error_message = $response->get_error_message();
        echo "Something went wrong: $error_message";
    } else {
        echo 'Response:<pre>';
        print_r( $response );
        echo '</pre>';
    }

What I’ve to do now at server2?

function getData(){
 if($_POST['username'])
    echo "TEST: " . $_POST['name'];
 //DOESN'T WORK 
}

But how can I fetch this data ($body) at server2/domain2? How to listen at server2, if server1 is sending me data?
I want to grap at server2 the data which I sent on server1 on save it in the DB.
Could someone show me a little example?

I’m sorry if this is pretty simple, but I’m quite new in APIs.
