Usage

Session Webservice

This webservice is needed for all other webservices but can also be used standalone (e.g. for using it with a service which is not supported by this library at the moment). Before you can use it you need to set up a credential class with all necessary informations.

<?php

$tId = 'abcd45678'; // FinanzOnline Teilnehmer-ID
$tUid = 'abcd45678'; // FinanzOnline Teilnehmer-UID (if available, otherwise leave blank)
$benId = 'abcd45678'; // FinanzOnline Benutzer-ID
$benPin = 'abcd45678'; // FinanzOnline Benutzer-PIN

$credential = new FonCredential($tId, $tUid, $benId, $benPin);

// Initialize
$sessionWs = new SessionWs($credential);

// Login
$sessionWs->login();

// Get session id
$sessionId = $sessionWs->getID();

// optional: logout. Not really needed cause you will be logged off at class destruct.
$sessionWs->logout();

---

VatID Check Webservice

Check a vat id (value added tax identification) for validity at two levels. First only return valid or not valid, second also return the company name and address if available.

// Initialize with previous created session webservice

/** @var SessionWs $sessionWs */
$checkVatIdWs = new VatIdCheckWs($sessionWs);

// Check at level one only returns valid
var_dump($checkVatIdWs->check('ATU36975500'));
/**
 * CSoellinger\FonWebservices\Result\VatIdCheck\ValidLevelOne
 *   valid => (bool) true
 */

// At level two you also get name and address of the organisation if available
var_dump($checkVatIdWs->check('ATU36975500', 2));
/**
 * CSoellinger\FonWebservices\Result\VatIdCheck\ValidLevelTwo
 *   name => (string) 'McDonald's Franchise GmbH'
 *   address => (string) 'Campus 21,Liebermannst A01601 AT-2345 Brunn am Gebirge'
 *   valid => (bool) true
 */

Databox Download Webservice

// Initialize with previous created session webservice

/** @var SessionWs $sessionWs */
$databoxDownloadWs = new DataboxDownloadWs($sessionWs);

// Get a list of your databox
$databoxList = $databoxDownloadWs->get();
var_dump($databoxList);
/**
 * array
 *   0 =>
 *     CSoellinger\FonWebservices\Result\DataboxDownload\ListItem
 *       stnr => (string) '99 999/9999'
 *       name => (string) 'Mustermann Max'
 *       anbringen => (string) 'STB-ZUSI'
 *       zrvon => (string) ''
 *       zrbis => (string) ''
 *       datbesch => (string) '2019-07-15+02:00'
 *       erltyp => (string) 'B'
 *       fileart => (string) 'PDF'
 *       ts_zust => (string) '2020-11-02T07:04:10.044+01:00'
 *       applkey => (string) '2019-07-15-11.45.07.000000'
 *       filebez => (string) '99_9999999_B_2008-11-20_2008-11-20-100948804630.PDF'
 *       status => (string) ''
 */

// Get one entry by the applkey
$entry = $databoxDownloadWs->getEntry($databoxList[0]->applkey);
var_dump($entry);
/**

Example(s)

The easiest way to start the examples is to start a PHP server:

php -S localhost:8005 --docroot ./examples

Now open your browser and go to http://localhost:8005

Setup

composer install

Quality Tools

This project uses modern PHP tooling for code quality:

Testing

• Pest - Modern testing framework with expressive syntax

  composer test              # Run Pest tests
  composer test:coverage     # Run tests with coverage report

Code Style & Formatting

• PHP-CS-Fixer - Automatic code style fixer (PSR-12)

  composer format            # Auto-fix code style
  composer format:check      # Check code style (for CI)

Static Analysis

• PHPStan - Static analysis tool (max level)
• Psalm - Static analysis and type checker (level 1)

  composer analyse           # Run PHPStan + Psalm
  composer analyse:phpstan   # Run PHPStan only
  composer analyse:psalm     # Run Psalm only

Automated Refactoring

• Rector - Automated code refactoring and upgrades

  composer rector            # Check for refactoring opportunities
  composer rector:fix        # Apply automated refactorings

Combined Checks

composer lint              # Check PHP syntax (parallel-lint)
composer check             # Run all quality checks (lint + format + analyse)

Multi-Version Testing with Podman

Test across all supported PHP versions using Podman Compose:

# Build all containers
podman-compose build

# Install/update dependencies (run after composer.json changes)
podman-compose run --rm php82 composer update

# Run tests on a specific PHP version
podman-compose run --rm php81 composer test
podman-compose run --rm php82 composer test
podman-compose run --rm php83 composer test
podman-compose run --rm php84 composer test

# Test all versions at once
bash bin/test-all-versions.sh

Supported PHP versions: 8.1, 8.2, 8.3, 8.4

Note: After modifying composer.json, you need to run composer update inside a container to update dependencies before running tests.
