PHP library which helps to call Sellsy's API

$client = new Client(['userToken'      => 'xxx', 'userSecret'     => 'xxx',
                      'consumerToken'  => 'xxx', 'consumerSecret' => 'xxx',
                     ]);
                     
var_dump($client->getService('Infos')->call('getInfos', []));
$promise = $client->getService('Infos')->callAsync('getInfos', [])->then(function($res) {
    var_dump($res);
});
$promise->wait();

How to install

First of all you need Composer:

php -r "readfile('https://getcomposer.org/installer');" | php

Then add Sellsy API as a dependency of your project:

php composer.phar require ferjul17/sellsy-api

How to use

Setup the library

The library provide you a class called Service which represent a part of the Sellsy's API. The service allows you to call api associated to this module. For instance, the service Accountdatas allows to call all method which start with Accountdatas in Sellsy's API, like Accountdatas.getTaxe or Accountdatas.updateUnit

The Services are created by a factory called Client. So you first need to create a Client before having a Service. To create a client just call its constructor. Its first argument is an array which contains the configuration. You must provide the credentials to call the API which include the user token and secret, and the consumer token and secret that you can find in Sellsy interface.

require 'path/to/vendor/autoload.php';
use SellsyApi\Client;

$client = new Client(['userToken'      => 'xxx', 'userSecret'     => 'xxx',
                      'consumerToken'  => 'xxx', 'consumerSecret' => 'xxx',
                     ]);

Call APIs

Once you have you client, you can retreive a Service by calling the method getService($serviceName):

$service = $client->getService('Accountdatas');

Finally, you can call an API with the method call($methodName, $params):

$response = $service->call('createUnit', ['unit' => ['value' => 'Kg']);

There's another method callAsync($methodName, $params) which send an asynchronous request and return a Promise:

$promise = $service->callAsync('createUnit', ['unit' => ['value' => 'Kg']);
$response = $promise->wait();

You can find more information about Promise here.

Handle errors

In order to handle errors, you should use retryable version of the previous methodes: retryableCall($callable) and retryableCallAsync($callable). In case of an error which is handle by the library, this one will try to send again the requests by calling $callable.

$callable must be a function which return the parameters to give to the call() and callAsync() methods.

$callable takes 3 arguments:

• The instance of the ServiceInterface used to send the call
• The retry number. The first time this value is 0.
• The error received

var_dump($client->getService('Infos')->retryableCall(function (ServiceInterface $service, $retry, $e) {
    if ($retry > 3) {
        throw $e;
    }
    return ['getInfos', []];
}));
$promise = $client->getService('Infos')->retryableCallAsync(function (ServiceInterface $service, $retry, $e) {
    if ($retry > 3) {
        throw $e;
    }
    return ['getInfos', []];
})->then(function ($res) {
    var_dump($res);
});
$promise->wait();
