Requirements

• A Client ID and Client Secret (You can generate them at https://xxx.personio.de/configuration/api/credentials)

Installation

In order to use this library, you need a PSR-18 HTTP Client, and a PSR-17 HTTP Message Factory.

Example using kriswallsmith/buzz and nyholm/psr7

composer require kriswallsmith/buzz nyholm/psr7 gamez/personio

$requestFactory = new \Nyholm\Psr7\Factory\Psr17Factory();
$httpClient = new \Buzz\Client\FileGetContents($requestFactory);

Example using guzzlehttp/guzzle and laminas/laminas-diactoros

composer require guzzlehttp/guzzle laminas/laminas-diactoros gamez/personio

$requestFactory = new \Laminas\Diactoros\RequestFactory();
$httpClient = new \GuzzleHttp\Client();

Usage

Basic API client

Once you have created an HTTP Client and Request Factory as described in the installation section, you can create an API client with them:

use Gamez\Personio\Api\HttpApiClient;

$clientId = 'xxx';
$clientSecret = 'xxx';

/**
 * @var \Psr\Http\Message\RequestFactoryInterface $requestFactory
 * @var \Psr\Http\Client\ClientInterface $httpClient
 */
$apiClient = HttpApiClient::with($clientId, $clientSecret, $httpClient, $requestFactory);

This API client allows you to make authenticated HTTP requests to the API of your Personio account - see Personio's REST API documentation for the endpoints you can use.

Simple API

Gamez\Personio\SimpleApi is the easiest and fastest way to access the data in your Personio account. Its methods are named after the available REST API endpoints and return arrays of data. You can inspect the available methods by looking at the source code of the Gamez\Personio\SimpleApi class or by using the autocompletion features of your IDE.

The Simple API doesn't get in your way when accessing the Personio API, but it doesn't provide additional features either. It will, for example, not tell you if you used a wrong query parameter or invalid field value, so you will have to rely on the returned API responses.

For information on which query parameters and field values are allowed, see Personio Developer Hub.

Catching errors

All exceptions thrown by this library implement the \Gamez\Personio\Exception\PersonioException interface. Exceptions thrown while using an API Client will throw a \Gamez\Personio\Exception\ApiClientError.

<?php 

use Gamez\Personio\Exception\ApiClientError;
use Gamez\Personio\Exception\PersonioException;

try {
    /** @var \Gamez\Personio\Api\ApiClient $apiClient */
    $result = $apiClient->get('nice-try');
} catch (ApiClientError $e) {
    $message = "Something went wrong while accessing {$e->getRequest()->getUri()}";

    if ($response = $e->getResponse()) {
        $message .= " ({$response->getStatusCode()})";
    }

    $message .= ' : '.$e->getMessage();

    exit($message);
} catch (PersonioException $e) {
    exit('Something not API related went really wrong: '.$e->getMessage());
}

Caching HTTP requests

To cache HTTP requests to the API, you can add a caching middleware/plugin to the HTTP client before injecting it into the API client instance. See the documentation of the respective component for instructions on how to do that.

• Guzzle: kevinrob/guzzle-cache-middleware
• HTTPlug: Cache Plugin

Creating your own API client

If you want to create your own API client, implement the \Gamez\Personio\Api\ApiClient interface and use your implementation.
