README

This library provides a wrapper for the Collmex API. It's not complete yet, some record types (and maybe some features) are missing.

Please create a pull request if you have implemented a new type/feature or create issues for bugs/feature requests.

There is (or least should be…) a Type class for every Collmex record type ("Satzart"). Currently, only the base types (MESSAGE, LOGIN, NEW_OBJECT_ID) and a few normal record types are implemented:

ABO_GET
ACC_BAL
ACCBAL_GET
ACCDOC
ACCDOC_GET

Compatibility

The Collmex PHP SDK requires PHP >= 8.1. It's possible to install an older version of the Collmex PHP SDK, if you're still using a no longer supported PHP version:

for PHP 7.3, 7.4 and 8.0 compatibility: use the 2.x tags (composer require mjaschen/collmex:^2.0); this version will receive security updates until version 4.0 is released.
for PHP 7.2 compatibility: use the 1.x tags (composer require mjaschen/collmex:^1.0); this version won't receive any updates.
for PHP 7.0 compatibility: use the 0.12.x tags (composer require mjaschen/collmex:^0.12); this version won't receive any updates.
for PHP 5.6 compatibility: use the 0.11.x tags (composer require mjaschen/collmex:^0.11); this version won't receive any updates.

New features will only go into the main branch and won't be backported.

Installation

Using Composer, just add it to your composer.json by running:

composer require mjaschen/collmex

If you want to use the included Laravel service provider CollmexServiceProvider, add it to the config/app.php providers array:

return [

    // ...

    'providers' => [
        // ...
        \MarcusJaschen\Collmex\CollmexServiceProvider::class,
    ],

    // ...
];

Upgrading

Version 2.x to 3.x

Read the change log. You will see the list of everything changed between versions 2 and 3.
Ensure your codebase is compatible with all requirements in composer.json.
Update your composer.json to require version 3.x of the Collmex PHP SDK:

{
  "require": {
    "mjaschen/collmex": "^3.0"
  }
}

Version 1.x to 2.x

Read the change log. You will see the list of everything changed between versions 1 and 2.
Ensure your codebase is compatible with all requirements in composer.json.
Rename attributes which are used in your codebase. Some attributes in the type classes have been renamed. If you use these attributes, you have to adjust your code as well. A simple search-and-replace is sufficient for this. Below you will find the complete list of renamed attributes:

Usage/Examples

Fetch from Collmex API

Load a Collmex Customer record:

use MarcusJaschen\Collmex\Client\Curl as CurlClient;
use MarcusJaschen\Collmex\Request;
use MarcusJaschen\Collmex\Type\CustomerGet;

// initialize HTTP client
$collmexClient = new CurlClient('USER', 'PASSWORD', 'CUSTOMER_ID');

// create request object
$collmexRequest = new Request($collmexClient);

// create a record type; we're querying the API for customer with ID=12345
$getCustomerType = new CustomerGet(array('customer_id' => '12345'));

// send HTTP request and get response object
$collmexResponse = $collmexRequest->send($getCustomerType->getCsv());

if ($collmexResponse->isError()) {
    echo 'Collmex error: ' . $collmexResponse->getErrorMessage() . '; Code=' . $collmexResponse->getErrorCode() . PHP_EOL;

    return;
}

$records = $collmexResponse->getRecords();

foreach ($records as $record) {
    // contains one Customer object and the Message object(s)
    var_dump($record->getData());
}

// show unparsed response contents:
var_dump($collmexResponse->getResponseRaw());

Fetch a PDF Invoice from Collmex

use MarcusJaschen\Collmex\Client\Curl as CurlClient;
use MarcusJaschen\Collmex\Request;
use MarcusJaschen\Collmex\Type\InvoiceGet;

$collmexRequest = new Request(new CurlClient('USER', 'PASSWORD', 'CUSTOMER_ID'));
$getInvoice = new InvoiceGet(['invoice_id' => '1', 'format' => InvoiceGet::FORMAT_ZIP]);

try {
    $collmexResponse = $collmexRequest->send($getInvoice->getCsv());
} catch (\Exception) {
    // Error Handling ...
}

/** @var \Symfony\Component\Finder\Finder $files */
$files = $collmexResponse->getFilesByType(type: 'pdf');

/** @var SplFileInfo $file */
foreach ($files as $file) {
    $pdfContent = file_get_contents($file->getPathname());
    // save, mail, display, etc.
    break;
}

Send Data to Collmex

Create a new Collmex Customer record and get the Collmex customer ID from the response data:

use MarcusJaschen\Collmex\Client\Curl as CurlClient;
use MarcusJaschen\Collmex\Request;
use MarcusJaschen\Collmex\Type\Customer;

// initialize HTTP client
$collmexClient = new CurlClient('USER', 'PASSWORD', 'CUSTOMER_ID');

// create request object
$collmexRequest = new Request($collmexClient);

// create a record type; we create a customer with some basic fields
$customer = new Customer(
    [
        'client_id' => '1',
        'salutation' => 'Herr',
        'firstname' => 'Charly',
        'lastname' => 'Cash',
        'street' => 'Hauptstraße 12',
        'zipcode' => '12222',
        'city' => 'Berlin',
        'inactive' => Customer::STATUS_ACTIVE,
        'country' => 'DE',
        'phone' => '+49300000000',
        'email' => 'cash@example.org',
        'output_medium' => Customer::OUTPUT_MEDIUM_EMAIL,
    ]
);

// send HTTP request and get response object
$collmexResponse = $collmexRequest->send($customer->getCsv());

if ($collmexResponse->isError()) {
    echo 'Collmex error: ' . $collmexResponse->getErrorMessage() . '; Code=' . $collmexResponse->getErrorCode() . PHP_EOL;

    return;
}

  $newObject = $collmexResponse->getFirstRecord();
  echo 'New Collmex customer ID=' . $newObject->new_id . PHP_EOL;

  $records = $collmexResponse->getRecords();

  foreach ($records as $record) {
      // contains one NewObject object and the Message object(s)
      var_dump($record->getData());
  }

Send Multiple Records at Once

The Collmex API accepts requests containing multiple records.

For example, a customer order with three line-items is sent as three CSV records/lines within a single request.

The MultiRequest class provides a simple way to send multiple records to Collmex at once. Any valid Type (or an array of valid Type instances) can be added to a queue and eventually sent to the Collmex API.

use MarcusJaschen\Collmex\Client\Curl as CurlClient;
use MarcusJaschen\Collmex\MultiRequest;
use MarcusJaschen\Collmex\Type\CustomerOrder;

// initialize HTTP client
$collmexClient = new CurlClient('USER', 'PASSWORD', 'CUSTOMER_ID');

// create request object
$collmexMultiRequest = new MultiRequest($collmexClient);

// create a record type; we create a CustomerOrder with some basic fields
$customerOrderData = [
    'client_id' => '1',
    'customer_salutation' => 'Herr',
    'customer_firstname' => 'Charly',
    'customer_lastname' => 'Cash',
    'customer_street' => 'Hauptstraße 12',
    'customer_zipcode' => '12222',
    'customer_city' => 'Berlin',
    'customer_country' => 'DE',
    'customer_phone' => '+49300000000',
    'customer_email' => 'cash@example.org',
    'order_date' => '01.01.1970',
    'status' => CustomerOrder::STATUS_CONFIRMED,
];

// set several item positions
$customerOrderItem = new CustomerOrder(
    array_merge(
        $customerOrderData,
        [
            'product_description' => 'erster Artikel',
            'quantity' => '1',
            'price' => '10,50',
            'tax_rate' => CustomerOrder::TAX_RATE_FULL,
        ]
    )
);
$collmexMultiRequest->add($customerOrderItem);

$customerOrderItem = new CustomerOrder(
    array_merge(
        $customerOrderData,
        [
            'product_description' => 'zweiter Artikel',
            'quantity' => '10',
            'price' => '37,99',
            'tax_rate' => CustomerOrder::TAX_RATE_REDUCED,
        ]
    )
);
$collmexMultiRequest->add($customerOrderItem);

$customerOrderItem = new CustomerOrder(
    array_merge(
        $customerOrderData,
        [
            'product_description' => 'Artikel Nummer drei',
            'quantity' => '3',
            'price' => '1250,00',
            'tax_rate' => CustomerOrder::TAX_RATE_FULL,
        ]
    )
);
$collmexMultiRequest->add($customerOrderItem);

// send HTTP request and get response object
$collmexResponse = $collmexMultiRequest->send();

if ($collmexResponse->isError()) {
    echo 'Collmex error: ' . $collmexResponse->getErrorMessage() . '; Code=' . $collmexResponse->getErrorCode() . PHP_EOL;

    return;
}

$newObject = $collmexResponse->getFirstRecord();
echo 'New Collmex order ID=' . $newObject->new_id . PHP_EOL;

$records = $collmexResponse->getRecords();

foreach ($records as $record) {
    // contains one NewObject object and the Message object(s)
    var_dump($record->getData());
}

Notes

Collmex expects all strings encoded in code page 1252 (Windows) while the Collmex PHP SDK expects all inputs as UTF-8 and outputs everything as UTF-8. The conversion of string encodings is done transparently by using the Symfony String Component and PHP's mb_convert_encoding() function before sending a request to the Collmex API and after receiving the response from the API.

Numeric / money values

This SDK does not convert numeric values to the string format required by the Collmex API by default.

For more information on format requirements, see the offical API documentation.

The library provides helpers for simple conversion from several types to the Collmex money format:

Fully qualified class name for the helper: \MarcusJaschen\Collmex\CollmexField\Money.

See the unit tests for more examples.

Date Values

Collmex unterstands two different formats for dates:

ISO style: YYYYMMDD
German style: DD.MM.YYYY

The library provides a helper to convert DateTime (which covers Carbon instances as well) from and to the Collmex date format:

use MarcusJaschen\Collmex\CollmexField\Date;

echo Date::toDateTime('20220921')->format('Y-m-d')
echo Date::toDateTime('12.08.2022')->format('Y-m-d')

This will output

2022-09-21
2022-08-12

To convert a DateTime instance to Collmex format (ISO style):

use MarcusJaschen\Collmex\CollmexField\Date;

echo Date::fromDateTime(new \DateTime('2022-09-21T00:00:00', new \DateTimeZone('Europe/Berlin')))

This will output

20220921

Development

Run code checks

To run checks and tests, it's the easiest to use the provided Composer scripts:

lint PHP files for syntax errors: composer ci:lint
run static analysis with Psalm and report errors: composer ci:psalm
run unit tests with PHPUnit: composer ci:tests
check the code style with PHP_CodeSniffer: composer ci:sniff

To run all checks and tests at once, just use composer ci.

Of course, it's possible to use the test runners directly, e.g. for PHPUnit:

./vendor/bin/phpunit

Psalm:

./vendor/bin/psalm

Autoformat the code

You can use a Composer script to autoformat the code:

composer fix:php-cs
