In this blog, we will see how we can increase access token life span by DocuSign refresh token in laravel, as you see by default access token life span is 8 hours and after that again you need the access token in order to call DocuSign API.
But by using the DocuSign refresh token we can again create the access token by which we call the API’s.
To call the refresh token API , remember you already have the refresh token which you get during the auth, if you don’t have the refresh token then please refer to this link.
If you have the refresh token then use the below code to get your new access token.
$client_id = env('DOCUSIGN_CLIENT_ID');
$client_secret = env('DOCUSIGN_CLIENT_SECRET');
$integrator_and_secret_key = "Basic " . utf8_decode(base64_encode("{$client_id}:{$client_secret}"));
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://account-d.docusign.com/oauth/token');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
$post = array(
'grant_type' => 'refresh_token',
'refresh_token' => Option::get_option('docusign_refresh_code'),
);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
$headers = array();
$headers[] = 'Cache-Control: no-cache';
$headers[] = "authorization: $integrator_and_secret_key";
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$result = curl_exec($ch);
if (curl_errno($ch)) {
echo 'Error:' . curl_error($ch);
}
curl_close($ch);
$decodedData = json_decode($result);I think the above code will help you to get the access token.
