Question

I am trying to get generate a token using curl. I am new to API generating tokens

<?php
    $username = '12345678'; //Fill with your app username Key
    $password = 'XXXXXXXXXXXXX'; // Fill with your app passowrd
    $headers = ['application/x-www-form-urlencoded'];
    $url = 'https://api.equitybankgroup.com/v1/token';
    $curl = curl_init($url);
    curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, TRUE);
    curl_setopt($curl, CURLOPT_HEADER, FALSE);
     $credentials = 'XXXXXXXXXXXXX'; //API Key
  curl_setopt($curl, CURLOPT_HTTPHEADER, array('Authorization: Basic '.$credentials));
    curl_setopt($curl, CURLOPT_USERPWD, $username.':'.$password);
    $result = curl_exec($curl);
    echo $result;
    curl_close($curl);

?>

I have tried posting in postman, and it generating well.

Try adding the request type option for the request.

curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,$vars);  //Post Fields
