Retrive submitted data on external page after redirect

When form redirection is set up, Instapage will pass over the submission id in redirection url. This can be used to retrieve submission data from our api on the page that you have redirected to.

Minimal php code to get submission details:

class InstapageSubmission
public $token;
public $access_token;
public $url = 'https://app.instapage.com/api/1/submission/';
public function __construct( $token, $access_token )
$this->token = $token;
$this->access_token = $access_token;
public function get( $submission_id = 0 )
$ch = curl_init(); 
curl_setopt($ch, CURLOPT_URL, $this->url . $submission_id );
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'TOKEN: '. $this->token,
'ACCESS: '. $this->access_token
$output = curl_exec($ch);
return json_decode( $output );
//To get Token and Access Token go to http://app.instapage.com/account/create-api-token
$token = 'YOUR TOKEN';
$access_token = 'YOUR ACCESS TOKEN';
$submission = new InstapageSubmission( $token, $access_token );
$submission_data = $submission->get( (int) $_GET[ 'submission' ] );
