Extensions:

Install

composer:
composer require sysix/lex-office-api

Usage

Search for the official API Documentation.
You need an API Key for that.

Basic

// store keys in .env file
$apiKey = getenv('LEXOFFICE_API_KEY'); 

// in this example we are using guzzlehttp/guzzle package, it can be any PSR-18 HTTP Client 
// see: https://packagist.org/providers/psr/http-client-implementation
$httpClient = \GuzzleHttp\Client();
$api = new \Sysix\LexOffice\Api($apiKey, $httpClient);

Optimize your HTTP Client

This library only prepares the \Psr\Http\Message\RequestInterface for the HTTP Client and returns its Response.
There are almost no error checks, no caching and no rate limiting. Your PSR-18 HTTP Client should come with a way to deal with it.

Here is a example with guzzlehttp/guzzle , kevinrob/guzzle-cache-middleware and spatie/guzzle-rate-limiter-middleware:

$apiKey = getenv('LEXOFFICE_API_KEY'); 

$stack = \GuzzleHttp\HandlerStack();
$stack->push(new \Kevinrob\GuzzleCache\CacheMiddleware\CacheMiddleware(), 'cache');
$stack->push(\Spatie\GuzzleRateLimiterMiddleware\RateLimiterMiddleware\RateLimiterMiddleware::perSecond(2));

$httpClient = \GuzzleHttp\Client(['handler' => $stack]);
$api = new \Sysix\LexOffice\Api($apiKey, $httpClient);
