Hello,

Processmaker has been running on our server for a couple years now without any issues. All of the sudden today my API script is failing during the pmRestLogin function with an HTTP status code of 0.

As far as I am aware nothing has changed. The client ID, secret, username and password are stored in a file called oauthAccess.json as described in the wiki. The function is the exact same as the wiki as well.

I run the authentication function and store the token in a variable to be called later for my REST api script. any idea as to why I am getting an HTTP status code of 0?

Code: Select all

$pmServer    = 'serverAddress';
$pmWorkspace = 'workspace';
function pmRestLogin($clientId, $clientSecret, $username, $password) {
   global $pmServer, $pmWorkspace;
   $postParams = array(
      'grant_type'    => 'password',
      'scope'         => '*',       //set to 'view_process' if not changing the process
      'client_id'     => $clientId,
      'client_secret' => $clientSecret,
      'username'      => $username,
      'password'      => $password
   );
 
   $ch = curl_init("$pmServer/$pmWorkspace/oauth2/token");
   curl_setopt($ch, CURLOPT_TIMEOUT, 30);
   curl_setopt($ch, CURLOPT_POST, 1);
   curl_setopt($ch, CURLOPT_POSTFIELDS, $postParams);
   curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
 
   $oToken = json_decode(curl_exec($ch));
   $httpStatus = curl_getinfo($ch, CURLINFO_HTTP_CODE);
   curl_close($ch);
 
   if ($httpStatus != 200) {
      print "Error in HTTP status code: $httpStatus\n";
      return null;
   }
   elseif (isset($oToken->error)) {
      print "Error logging into $pmServer:\n" .
         "Error:       {$oToken->error}\n" .
         "Description: {$oToken->error_description}\n";
   }
   else {
      //At this point $oToken->access_token can be used to call REST endpoints.
 
      //If planning to use the access_token later, either save the access_token
      //and refresh_token as cookies or save them to a file in a secure location.
 
      //If saving them as cookies:
      //setcookie("access_token",  $oToken->access_token,  time() + 86400);
      //setcookie("refresh_token", $oToken->refresh_token); //refresh token doesn't expire
      //setcookie("client_id",     $clientId);
      //setcookie("client_secret", $clientSecret);
 
      //If saving to a file:
      file_put_contents("/location/oauthAccess.json", json_encode($oToken));
   }
 
   return $oToken;
}
//--------------------------------------------------------------------------
//include the path in the filename if not located in the same directory:
$json = file_get_contents("oauthCredentials.json") or
   die("Error: Unable to open file oauthCredentials.json.");
 
$oCred = json_decode($json);
 
if (empty($oCred) or !isset($oCred->client_id)){
   die("Error: oauthCredentials.json file lacks credentials or JSON string can't be decoded.");
}
$oToken = pmRestLogin($oCred->client_id, $oCred->client_secret, $oCred->username, $oCred->password);

$accessToken = $oToken->access_token;

Hi gevans1,

It is very possible that you should generate a new API key again inside the ProcessMaker, it seems to me that it has only one year of use, and it has an expiration date.

I hope I helped you
