PHP Client

A reference implementation meant as an example how to use the PSB api using PHP.

Requirements

• PHP 7.2 or greater

Install

• Install library using composer.

composer require everbinding/econnect-psb-php

Then include composer autoloader.

require __DIR__ . '/vendor/autoload.php';

Configure

$config = \EConnect\Psb\Configuration::getDefaultConfiguration();

$config
    ->setUsername("{username}")
    ->setPassword("{password}");
    ->setClientId("{clientId}")
    ->setClientSecret("{clientSecret}")
    ->setHost("https://psb.econnect.eu")
    ->setApiKey('Subscription-Key', '{subscription key}');

Login

Login using the default configuration.

$config = \EConnect\Psb\Configuration::getDefaultConfiguration();

$authN = new \EConnect\Psb\Authentication($config);
$authN->login();

Use api

Use the api using the default configuration after a successful login. In this example we are calling the send sales invoice api. The user must have send permission on the provide sender partyId. Also make sure the UBL is valid, otherwise it will be block for sending. The receiver partyId is optional, the PSB will use the best possible route we no receiver partyId is provided.

$config = \EConnect\Psb\Configuration::getDefaultConfiguration();

$salesInvoiceApi = new EConnect\Psb\Api\SalesInvoiceApi(
    new GuzzleHttp\Client();
    $config
);

$yourPartyId = "senderPartyId";
$filePath = "./Ubl.xml";
$receiverPartyId = null;

$salesInvoiceApi->sendSalesInvoice($yourPartyId, $filePath, $receiverPartyId);

Example client

There is a simple example php client that you can run on a php webserver. With the example you can send an invoice via Peppol. Also there is a webhook receiver example that you need to have in order to receive invoices from Peppol.

Build your own source

Instead of using this code, you could also generate the php code yourself using the openapi-generator-cli.

openapi-generator-cli generate -g php -i https://psb.econnect.eu/v1/swagger.json?subscriptionKey={your-subscription} -o C:\temp --additional-properties=invokerPackage=EConnect\Psb

And use Jumbojett\OpenIDConnectClient to get the access token. You can also copy the code from: Authentication.php

use Jumbojett\OpenIDConnectClient;

$oidc = new OpenIDConnectClient('https://identity.econnect.eu',
                                '{clientId}',
                                '{clientSecret}');

$oidc->addScope('ap');

// Add username and password
$oidc->addAuthParam(array('username'=>'{username}'));
$oidc->addAuthParam(array('password'=>'{password}'));

// to validate the JWT and whether the acces_token property is present
$token = $oidc->requestResourceOwnerToken(TRUE)->access_token;
