Glad to hear that. You can place the code inside a special file, lets say authentication.php and then include this file into the header.php.

Basically, the page where the user will get redirectes back to. The uri you set in the link. That page will need to have the file included

To give a bit more detail. 

I have a file authentication.php

```
<?php
  if (isset($_GET['code'])) {

    // Params for POST request
    $data = array(
        'code' => $_GET['code'],
        'client_secret' => SC_CLIENT_SECRET
    );

    $payload = json_encode($data);

    // Prepare new cURL resource
    $ch = curl_init('https://steemconnect.com/api/oauth2/token');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLINFO_HEADER_OUT, true);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $payload);

    // Set HTTP Header for POST request
    curl_setopt($ch, CURLOPT_HTTPHEADER, array(
        'Content-Type: application/json',
        'Content-Length: ' . strlen($payload))
    );

    // Submit the POST request
    $result = curl_exec($ch);

    // Close cURL session handle
    curl_close($ch);

    $json = json_decode($result);
    $date = date("Y/m/d H:G:s", time() + $json->expires_in);

    // Add tokens to the database
    global $wpdb;
    $wpdb->query("INSERT INTO `steem_authorization` (`id`, `access_token`, " .
    "`user_login`, `expires_in`, `refresh_token`) VALUES (NULL, " .
    "'" . $json->access_token . "', '" . $json->username ."', '" .
    $date . "', '" . $json->refresh_token ."') ON DUPLICATE KEY UPDATE " .
    "`user_login`='" . $json->username ."';");
  }

?>
```

The client secret, I set that in wp-config.php

```
'client_secret' => SC_CLIENT_SECRET
```

Then inside the template file of the page I want to add a authorise button I have added the following code:
```
// import steemconnet authentication
include 'authenticate.php';

// see if current user is logged in and has authenticated voting
// permissions in the database
global $wpdb;
$current_user = wp_get_current_user();
```
This includes the file and get the username.

Then lasty I check if the user has already authorised the app if not it shows a button to do so.

```
echo '<div>';
// Check if user is logged in
if ($current_user->user_login == ''){
  echo '<div align="center"><br><h1>You need to <a href="https://ste' .
  'emautomated.eu/wp-login.php?action=wordpress_social_authenticate&' .
  'mode=login&provider=Steemconnect&redirect_to=' . get_permalink() .
  '">log in</a></h1></div>';
} else {
  // Check if logged in user has authorised the app
  $results = $wpdb->get_results('SELECT * FROM `steem_authorization` ' .
  'WHERE `user_login` = "' . $current_user->user_login . '"');
      if (count($results) == 0){
        echo '<div align="center"><h1><br>Authorize <font color=' .
        '"blue">@steemautomated</font> to vote for you.</h1><br><a ' .
        'class="maxbutton-1 maxbutton maxbutton-steemconnect" href=' .
        '"https://steemconnect.com/oauth2/authorize?client_id=' .
        'steemautomated&redirect_uri=' . get_permalink() .'&response_' .
        'type=code&scope=offline,vote"><span class="mb-text">' .
        'Authorize</span></a></div><br>';
  }
}
echo '</div>';
```
