Ultipro SDK for PHP (Unofficial)

Download the Library

If you're having trouble with Ultimate Software's REST APIs, this library will help you get a head start.

This is an unofficial library to allow seamless connections to Ultipro’s REST API via PHP.

This library was created because Ultimate Software does not have any SDK and none of their documentation lays out how to use PHP for any of it.


composer require brianfreytag/ultipro-sdk-php



You can authenticate in the Client in one of two ways: 1) Authentication Object, 2) Array

Authentication Object:

use Ultipro\Authentication;
use Ultipro\UltiproClient;
$username = 'my-username';
$password = 'my-password';
$customerApiKey = 'XY0XY';
$authorization = new Authentication($username, $password, $customerApiKey);
$client = new UltiproClient($authorization);


use Ultipro\UltiproClient;
$username = 'my-username';
$password = 'my-password';
$customerApiKey = 'XY0XY';
$authorization = [
    'username'         => $username,
    'password'         => $password,
    'customer_api_key' => $customerApiKey
$client = new UltiproClient($authorization);

Client Arguments

The client takes three arguments:

  1. $auth – Authentication (see above)
  2. $baseURi – Found in Ultipro -> Configuration -> Security -> Web Services (Defaults to
  3. $options – Guzzle Request Options to overwrite defaults (

Choosing a Client

You can use the default UltiproClient to manually do GET and POST requests, or you can utilize alternate clients for each Ultipro API endpoint “groups”. This version includes clients for the following endpoints:

const ENDPOINT_CONFIG_ORG_LEVELS            = '/configuration/v1/org-levels';
const ENDPOINT_PERSONNEL_PERSON_DETAIL      = '/personnel/v1/person-details';
const ENDPOINT_PERSONNEL_EMPLOYMENT_DETAIL  = '/personnel/v1/employment-details';
const ENDPOINT_PERSONNEL_EMPLOYEE_ID_LOOKUP = '/personnel/v1/employee-ids';

For endpoints with PERSONNEL, use the PersonnelClient. For the endpoints with CONFIG use the ConfigurationClient.

Using a Client

For Personnel queries, utilize the Ultipro\Personnel\PersonnelClient client.

Each client method accepts a Request object that implements the RequestInterface interface.

The RequestInterface receives query parameters from classes that extend the base Query. Nearly every endpoint accepts different query parameters, so under the various endpoint namespaces, there are different *Query classes under the Query directory that will accept different data to search the endpoints.

Here is a simple example of pulling Person Detail API data utilizing an Employee ID (as defined from Ultipro):

use Ultipro\Personnel\PersonnelClient;
use Ultipro\Authentication;
use Ultipro\Personnel\Query\PersonDetailQuery;
use Ultipro\Personnel\Model\PersonDetail;
use Ultipro\Personnel\PersonnelResponse;
use Ultipro\Request;
$username = 'my-username';
$password = 'my-password';
$customerApiKey = 'XY0XY';
$authorization = new Authentication($username, $password, $customerApiKey);
$personnelClient = new PersonnelClient($authorization);
$request = new Request();
$query = new PersonDetailQuery();
/** @var PersonnelResponse $response */
$response = $personnelClient->getPersonDetails($request);
/** @var PersonDetail $personDetail */
foreach ($response->getContent() as $personDetail) {
    $firstName = $personDetail->getFirstName();


There is still a lot of work to do in this library, including many endpoints to implement.
