To get “Account SID” and “Auth Token” of the Twilio account, Please follow below steps:

Step-2:  Copy “Account SID”, “Auth Token” and “Phone Number”.

You can use this code any hook like “wp_ajax” and “init” action. Add below code in functions.php,

$username = "Account SID";
$password = "Auth Token";
$auth = base64_encode( $username . ':' . $password );
$args = [
  'headers' => [
    'Authorization' => "Basic $auth",
    'Content-Type'  => 'application/x-www-form-urlencoded;charset=UTF-8',
  ],
  'body'    => [
    "Body" => 'Testing twilio message body',
    "To"   => "Receiver Mobile Number",
    "From" => "Twillio Register Mobile Number",
  ],
];       
  
$response      = wp_remote_post( 'https://api.twilio.com/2010-04-01/Accounts//Messages.json', $args );
$response_body = wp_remote_retrieve_body( $response );

Here,
Username : Account SID,
Password : Auth Token
To : Receiver Mobile Number
From : Twillio Register Mobile Number
