Single sign-on Sample scripts

Below are two sample PHP scripts for setting up Visit Partner single sign-on (see Single sign-on). These scripts are provided only as examples and may not work as-is. If you have any questions regarding this implementation, the Visit and Poken by GES development team is ready and willing to advise you.

You need a shared key and event code to complete your script. See Shared key and event code for more information.

Example 1

1. <?php
2. $sharedKey = 'xxxxxx'; // shared key of organisation, see note below
4. // Make sure parameters are specified in alphabetical order for correct calculation of hash
5. $request = array(
6. 'contactref' => 'yyyy',  // reference to partner as set when importing them or via API
7. 'expo' => 'zzzzzzz', // expo code from visit
8. 'time' => time()
9. );
11. // create a hash from un-encoded query string and sign with pre-shared-key
12. $hashSource = urldecode(http_build_query($request)) . $sharedKey;
13. echo "HASH is taken from SHA256('" .$hashSource . "')<br/>";
15. // checksum based on alphabetically ordered name/value pairs with appended sharedkey
16. $request['check'] = hash('sha256', $hashSource);
17. echo "<form action='https://account.n200.com/partner/loginauth' method='POST'>";
18. foreach ($request as $key => $value) {
19. echo "<input type='text' name='". $key ."' value='" . $value ."'/>";
20. }
21. echo "<input type='submit' value='Submit'/></form>";

Example 2

1. <?php
2. $sharedKey = 'xxxxx'; // shared key of organisation, see note below
3. $request = array(
4. 'contactref' => ‘yyyyyy’, // reference to partner as set when importing them or via API
5. 'expo' => 'zzzzzzzzzz',
6. 'time' => time()
7. );
9. // create a hash from un-encoded query string and sign with pre-shared-key
10. $request['check'] = hash('sha256', urldecode(http_build_query($request)) . $sharedKey);
11.  
12. $ch = curl_init('https://account.n200.com/partner/loginauth');
13.  
14. curl_setopt_array($ch, array(
15. CURLOPT_POST => true,
16. CURLOPT_FOLLOWLOCATION => false,
17. CURLOPT_RETURNTRANSFER => true,
18. CURLOPT_POSTFIELDS => http_build_query($request)
19. ));
21. curl_exec($ch);
23. $info = curl_getinfo($ch);
25. header('Location: '. $info['redirect_url']);

If Partners are added manually you will need to use the Partner Code as reference. This example below would replace lines 5-10 in Example 1 and lines 4-8 in Example2.

// Make sure parameters are specified in alphabetical order for correct calculation of hash$request = array(    'partner' => 'dfgoiui44',    'time' => time());

You can find your SharedKey at Organisation – Organisation Profile.
