Trouble with Rest API using Curl in PHP [duplicate]

Question

I'm trying to use the REST API of a telecommunications company to return an access token using curl, here is my code:

<?php

$curl = curl_init();

curl_setopt_array($curl, [
  CURLOPT_URL => "https://api.touch.technology/auth/token",
  CURLOPT_POST=> true,
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_CUSTOMREQUEST => "POST",
  CURLOPT_POSTFIELDS => "grant_type=client_credentials&client_id=*********&client_secret=*********",
  "content-type: x-www-form-urlencoded",
]);
$data = curl_exec($curl);
curl_close($curl);
var_dump($data);

?>

Yet all i recive is "string(12) "Unauthorized""

Can anybody tell me where im going wrong?

:API Docs

"content-type: x-www-form-urlencoded" isn't a valid setopt option. — Phil

hope this helps, check the comments for explanation

<?php
$curl = curl_init();

curl_setopt_array($curl, [
  CURLOPT_URL => "https://api.touch.technology/auth/token",
  CURLOPT_POST=> true,
  CURLOPT_RETURNTRANSFER => true,
  //you have CURLOPT_POST set to true so don't need this
  //CURLOPT_CUSTOMREQUEST => "POST", 
  //CURLOPT_POSTFIELDS => "grant_type=client_credentials&client_id=*********&client_secret=*********",
  //don't need this
  //"content-type: x-www-form-urlencoded",
  //client secret and client_id must be url encoded
  CURLOPT_POSTFIELDS => "grant_type=client_credentials&client_id=".urlencode(*********)."&client_secret=".urlencode(*********)
]);
$data = curl_exec($curl);
curl_close($curl);
var_dump($data);

?>

you can try to use www.hurlit.com to test the API and make sure it works with the data you have (secret and key) and then try it out with curl.

It's easier to use http_build_query() for the postfields

its true http_build_query() is easier @Phil thanks for the edit
