Usage

Initialization

Before using any functionality, you need to initialize the DCL client with your credentials:

use OxygenSuite\DigitalClient\Http\DCLRequest;

// Initialize with your credentials
$env = 'dev'; // 'production' for production environment
$userId = 'your-user-id';
$subscriptionKey = 'your-subscription-key';

DCLRequest::init($userId, $subscriptionKey, $env);

Create a Digital Client

To create a new digital client:

use OxygenSuite\DigitalClient\Enums\ClientServiceType;
use OxygenSuite\DigitalClient\Http\SendClient;
use OxygenSuite\DigitalClient\Models\DigitalClient;
use OxygenSuite\DigitalClient\Models\Workshop;

// Create a new digital client
$dcl = DigitalClient::create()
    ->setClientServiceType(ClientServiceType::WORKSHOP)
    ->setBranch(1)
    ->setComments('Your comments here')
    ->setUseCase(
        (new Workshop())
            ->setVehicleRegistrationNumber('REGISTRATION_NUMBER')
            ->setVehicleCategory('CATEGORY')
            ->setVehicleFactory('FACTORY'),
    );

// Send the client to DCL
$request = new SendClient();
try {
    $responses = $request->handle($dcl);

    foreach ($responses as $response) {
        if ($response->isSuccessful()) {
            // Get the new client DCL ID
            $dclId = $response->getNewClientDclID();
            // Process successful response
        } else {
            // Handle errors
            foreach ($response->getErrors() as $error) {
                // Process error
            }
        }
    }
} catch (DCLException $e) {
    // Handle communication error
    echo "Communication error: " . $e->getMessage();
}

Update a Digital Client

To update an existing digital client:

use OxygenSuite\DigitalClient\Enums\ClientServiceType;
use OxygenSuite\DigitalClient\Enums\InvoiceType;
use OxygenSuite\DigitalClient\Enums\ProvidedCategoryServiceType;
use OxygenSuite\DigitalClient\Http\UpdateClient;
use OxygenSuite\DigitalClient\Models\DigitalClient;

// Update an existing digital client
$updateClient = DigitalClient::update()
    ->setInitialDclId('your-dcl-id')
    ->setClientServiceType(ClientServiceType::WORKSHOP)
    ->setEntryCompletion(true)
    ->setAmount(150.25)
    ->setIsDiffVehReturnLocation(false)
    ->setProvidedServiceCategory(ProvidedCategoryServiceType::WORK_WITH_PARTS)
    ->setInvoiceKind(InvoiceType::RETAIL)
    ->setComments('Update comments');

// Send the update request
$request = new UpdateClient();
try {
    $responses = $request->handle($updateClient);

    foreach ($responses as $response) {
        if ($response->isSuccessful()) {
            // Get the updated client DCL ID
            $updatedDclId = $response->getUpdatedClientDclID();
            // Process successful response
        } else {
            // Handle errors
            foreach ($response->getErrors() as $error) {
                // Process error
            }
        }
    }
} catch (DCLException $e) {
    // Handle communication error
    echo "Communication error: " . $e->getMessage();
}

Correlate a Digital Client with an invoice

To correlate a digital client with another entity:

use OxygenSuite\DigitalClient\Http\ClientCorrelations;
use OxygenSuite\DigitalClient\Models\ClientCorrelation;

// Create a correlation
$correlateClient = (new ClientCorrelation())
    ->setMark('your-mark-number')
    ->addCorrelatedDCLid('your-dcl-id');

// Send the correlation request
$request = new ClientCorrelations();
try {
    $responses = $request->handle($correlateClient);

    if ($responses->isSuccessful()) {
        // Process successful response
        $correlateId = $response->getClientCorrelationId();
    } else {
        // Handle errors
    }
} catch (DCLException $e) {
    // Handle communication error
    echo "Communication error: " . $e->getMessage();
}

Cancel a Digital Client

To cancel a digital client:

use OxygenSuite\DigitalClient\Http\CancelClient;

// Create a cancel request
$request = new CancelClient();
try {
    $responses = $request->handle('your-dcl-id');
    $response = $responses->first(); //There is only one response

    if ($response->isSuccessful()) {
        // Get the cancellation ID
        $cancellationId = $response->getCancellationID();
        // Process successful response
    } else {
        // Handle errors
        foreach ($response->getErrors() as $error) {
            // Process error
        }
    }
} catch (DCLException $e) {
    // Handle communication error
    echo "Communication error: " . $e->getMessage();
}

Retrieve Digital Clients

To retrieve sent data:

use OxygenSuite\DigitalClient\Http\RequestClients;

$request = new RequestClients();

try {
    $response = $request->handle(100000000028013);

    print_r($response->toArray());
} catch (DCLException $e) {
    echo $e->getMessage();
}

Upgrading

Special Thanks

This package was inspired by the excellent work done in the firebed/aade-mydata package. I would like to express my gratitude to the developers of that project, as some of the core code and concepts from their implementation have been adapted and utilized in this package.
