Code organization

System depends on the UBL standard to create the objects that are to be sent to SEF.
UBL implementation that library depends on.
All responses from the SEF are built as objects in the Model directory. Storing response results from the SEF is currently done in file system. Support for other types of storage is covered through the use of StorageInterface
Cache folder is by default in location /tmp/sefStorage.
Some of SEF responses are large so API can take some time to cache.

UBL directory contains adapters over standard UBL formats for the purpose of constructing the UBL for SEF and removing the complexity of class instantiation.

Example usage

Initial setup before every API call

$browser = new \React\Http\Browser(); // Used for all the API calls
$apiKey = '*****'; // Obtain key from SEF
$apiService = new \i3or1s\EFakture\Util\EFaktureApi($browser, $apiKey); // Set of available API calls

Retrieve available units

$UnitMeasures = new \i3or1s\EFakture\Service\UnitMeasures();
$measures = $UnitMeasures->retrieve($apiService);
print_r($measures);

Retrieve available companies

$storageManager = new \i3or1s\EFakture\Storage\StorageManager(new \i3or1s\EFakture\Storage\FileSystemStorage(__DIR__.'/cache'));
$companies = new \i3or1s\EFakture\Service\Companies();
$companiesResourceStream = new \i3or1s\EFakture\ResourceStream\FileSystemResourceStream($storageManager->storage, EFakturaAPIRoutes::GET_ALL_COMPANIES->SEFObject());

$listOfCompanies = $companies->retrieve($apiService, $companiesResourceStream, 0,3);
print_r($listOfCompanies);

Find company

For this call to work you should have generated list of companies in the cache.

$storageManager = new \i3or1s\EFakture\Storage\StorageManager(new \i3or1s\EFakture\Storage\FileSystemStorage(__DIR__.'/cache', true));
$companies = new \i3or1s\EFakture\Service\Companies();
$companiesResourceStream = new \i3or1s\EFakture\ResourceStream\FileSystemResourceStream($storageManager->storage, EFakturaAPIRoutes::GET_ALL_COMPANIES->SEFObject());

$listOfCompanies = $companiesResourceStream->getStorageInterface()->seek(EFakturaAPIRoutes::GET_ALL_COMPANIES->SEFObject(), [
    "registrationCode" => "08804516"
]);
print_r($listOfCompanies);

Retrieve TAX exemption reasons

For this call to work you should have generated list of companies in the cache.

$storageManager = new \i3or1s\EFakture\Storage\StorageManager(new \i3or1s\EFakture\Storage\FileSystemStorage(__DIR__.'/cache'));
$taxExemptionListService = new \i3or1s\EFakture\Service\ValueAddedTaxExemptionReasonList();
$taxExemptionResourceStream = new \i3or1s\EFakture\ResourceStream\FileSystemResourceStream($storageManager->storage, EFakturaAPIRoutes::VALUE_ADDED_TAX_EXEMPTION_LIST->SEFObject());
$taxExemptionList = $taxExemptionListService->retrieve($apiService, $taxExemptionResourceStream, 0,1);
print_r($taxExemptionList);

Create and send invoice

Note: Company data should be valid in SEF in order for this to work

$invoice = new \i3or1s\EFakture\UBL\Invoice(
    new \i3or1s\EFakture\UBL\InvoiceDetails(
        'invoice number (01/2022)', new DateTimeImmutable(), new DateTimeImmutable('+ 7days'), new \i3or1s\EFakture\UBL\CBC\InvoiceTypeCode(\i3or1s\EFakture\UBL\CBC\InvoiceTypeCode::COMMERCIAL_INVOICE),
        'RSD', new \i3or1s\EFakture\UBL\CAC\InvoicePeriod(\i3or1s\EFakture\UBL\CAC\InvoicePeriod::DELIVERY_ACTUAL_DATE),
        '123456', new DateTimeImmutable('+ 7days')

    ),
    new \i3or1s\EFakture\UBL\Party(
        'company PIB', null, 'company name', null, 'city', 'RS',
        'company Identification', 'e-mail address', true
    ),
    new \i3or1s\EFakture\UBL\Party(
        'company PIB', null, 'company name', 'address', 'city',
        'RS','company Identification', 'e-mail address', true
    ),
    new \i3or1s\EFakture\UBL\PaymentMeans(
        '30', '(mod97) 123456/2022', 'Tekući račun pravnog lica'
    ),
    [
        new \i3or1s\EFakture\UBL\TaxSubtotal(2801.15, 20),
        new \i3or1s\EFakture\UBL\TaxSubtotal(1825.28, 10),
        new \i3or1s\EFakture\UBL\TaxSubtotal(1560, 0, null, 'PDV-RS-11-1-4'),
    ],
    6186.43, 6186.43, 6929.19, 0, 0, 6929.19,
    [
        new \i3or1s\EFakture\UBL\InvoiceLine(5, $unitMeasures['MTR'], 560.23, 'test item 1', 20, 1),
        new \i3or1s\EFakture\UBL\InvoiceLine(4, $unitMeasures['KMT'], 456.32, 'test item 2', 10, 2),
        new \i3or1s\EFakture\UBL\InvoiceLine(1, $unitMeasures['H87'], 1560, 'test item 3', 0, 3),
    ]
);

$invoiceService = new \i3or1s\EFakture\Service\Invoice();
$sefResponse = $invoiceService->send($apiService, $invoice);
print_r($sefResponse);
