Twilio not working with curl php

First of all, since API's URL is secured, you have to disable SSL peer verification by setting CURLOPT_SSL_VERIFYPEER option to false.

Furthermore, according to API docs, URL of request is account-dependent, i.e. it should be built based on your account sandbox ID:

https://api.twilio.com/2010-04-01/Accounts/{AccountSid}/Messages

So the code should look like this:

$id = "SANDBOX_ACC_ID";$token = "SANDBOX_TOKEN";$url = "https://api.twilio.com/2010-04-01/Accounts/$id/SMS/Messages";$from = "+MAGICNUMBER";$to = "+XXXXXXXXXX"; // twilio trial verified number$body = "using twilio rest api from Fedrick";$data = array (    'From' => $from,    'To' => $to,    'Body' => $body,);$post = http_build_query($data);$x = curl_init($url );curl_setopt($x, CURLOPT_POST, true);curl_setopt($x, CURLOPT_RETURNTRANSFER, true);curl_setopt($x, CURLOPT_SSL_VERIFYPEER, false);curl_setopt($x, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);curl_setopt($x, CURLOPT_USERPWD, "$id:$token");curl_setopt($x, CURLOPT_POSTFIELDS, $post);$y = curl_exec($x);curl_close($x);var_dump($post);var_dump($y);

Here is a PHP - Curl implementation in a callable function

function send_sms($number,$body){    $ID = '1234567890abcdef1234567890abcdef12';    $token = '1234567890abcdef1234567890abcdef';    $service = 'AB1234567890abcdef1234567890abcdef';    $url = 'https://api.twilio.com/2010-04-01/Accounts/' . $ID . '/Messages.json';    $ch = curl_init();    curl_setopt($ch, CURLOPT_URL,$url);    curl_setopt($ch, CURLOPT_FOLLOWLOCATION,true);    curl_setopt($ch, CURLOPT_RETURNTRANSFER,true);    curl_setopt($ch, CURLOPT_HTTPAUTH,CURLAUTH_BASIC);    curl_setopt($ch, CURLOPT_USERPWD,$ID . ':' . $token);    curl_setopt($ch, CURLOPT_POST,true);    curl_setopt($ch, CURLOPT_POSTFIELDS,        'To=' . rawurlencode('+' . $number) .        '&MessagingServiceSid=' . $service .        //'&From=' . rawurlencode('+18885550000') .        '&Body=' . rawurlencode($body));    $resp = curl_exec($ch);    curl_close($ch);    return json_decode($resp,true);}

$ID and $token can be found under SMS / Dashboard / 'Show API Credentials'https://www.twilio.com/console/sms/dashboard

(Optional) $service can be found under SMS / Messaging Services / 'SID' https://www.twilio.com/console/sms/services

Comment out 'MessagingServiceSid=' and uncomment 'From=' to use direct sending from a single phone number

Finally, key information can be found buried in the kb here https://www.twilio.com/docs/sms/send-messages#send-a-message-with-an-image-url
