Disclaimer

This package is an unofficial API client for SevDesk. It is not affiliated with, officially maintained, or endorsed by SevDesk GmbH. SevDesk is a trademark of SevDesk GmbH.

This package is provided as-is for integration purposes. Users must comply with SevDesk's API terms of service.

Requirements

• PHP 8.1 or higher
• Saloon v3

Installation

You can install the package via composer:

composer require ameax/sevdesk-api-client

Configuration

Getting Your API Token

1. Log in to your SevDesk account
2. Go to Settings → Users & Rights → Users
3. Click on your user
4. In the "API Token" section, you'll find your 32-character hexadecimal token
5. Click "Generate new" if you need a new token

Standalone Usage (Without Laravel)

use Ameax\SevDeskApi\SevDesk;

// Option 1: Simple initialization with API token
$sevdesk = new SevDesk('your_32_character_hexadecimal_token');

// Option 2: Initialize with array configuration
$sevdesk = new SevDesk([
    'api_token' => 'your_32_character_hexadecimal_token',
    'base_url' => 'https://my.sevdesk.de/api/v1', // optional, this is the default
    'user_agent' => 'My App/1.0', // optional
    'timeout' => 30, // optional, in seconds
]);

// Option 3: Initialize and configure separately
$sevdesk = new SevDesk();
$sevdesk->setApiToken('your_32_character_hexadecimal_token')
    ->setConfig('timeout', 60)
    ->setConfig('user_agent', 'My App/1.0');

Laravel Usage

1. Publish Configuration (Optional)

If you want to use Laravel's configuration system:

php artisan vendor:publish --tag=sevdesk-config

2. Add Environment Variables

Add your SevDesk API token to your .env file:

SEVDESK_API_TOKEN=your_32_character_hexadecimal_token
SEVDESK_BASE_URL=https://my.sevdesk.de/api/v1
SEVDESK_TIMEOUT=30

3. Usage in Laravel

use Ameax\SevDeskApi\SevDesk;

// Get the SevDesk instance from the container
$sevdesk = app(SevDesk::class);

// Or use dependency injection
public function __construct(private SevDesk $sevdesk) {}

// Or create a custom service
namespace App\Services;

use Ameax\SevDeskApi\SevDesk;

class SevDeskService
{
    protected SevDesk $connector;
    
    public function __construct(string $apiToken)
    {
        $this->connector = new SevDesk($apiToken);
    }
    
    public function connector(): SevDesk
    {
        return $this->connector;
    }
}

Usage Examples

Working with Contacts

// Get all contacts (organizations and persons)
$response = $sevdesk->contact()->getContacts('1', null);
$contacts = $response->json('objects') ?? [];

// Get only organizations
$response = $sevdesk->contact()->getContacts('0', null);

// Get contact by customer number
$response = $sevdesk->contact()->getContacts(null, 'CUST-12345');

// Get a specific contact by ID
$response = $sevdesk->contact()->getContactById(123456);
$contact = $response->json('objects.0');

// Create a new contact (organization)
$request = new \Ameax\SevDeskApi\Requests\Contact\CreateContact();
$request->body()->set([
    'name' => 'ACME Corporation',
    'status' => 100, // 100 = Active
    'customerNumber' => 'CUST-' . time(),
    'category' => [
        'id' => 3, // 3 = Organization, 1 = Person
        'objectName' => 'Category'
    ],

    status: null,        // null for all, 50 = draft, 100 = open, 200 = paid
    invoiceNumber: null,
    startDate: null,
    endDate: null,
    contactId: null,
    contactObjectName: null
);
$invoices = $response->json('objects') ?? [];

// Get a specific invoice
$response = $sevdesk->invoice()->getInvoiceById($invoiceId);

// Create an invoice using the factory pattern
$request = new \Ameax\SevDeskApi\Requests\Invoice\CreateInvoiceByFactory();
$request->body()->set([
    'invoice' => [
        'invoiceNumber' => 'RE-10001',
        'contact' => [

Error Handling

try {
    $response = $sevdesk->contact()->getContacts('1', null);
    
    if ($response->successful()) {
        $contacts = $response->json('objects') ?? [];
        // Process contacts
    } else {
        // Handle API error
        $error = $response->json();
        $statusCode = $response->status();
        
        switch ($statusCode) {
            case 401:
                throw new Exception('Invalid API token');
            case 404:
                throw new Exception('Resource not found');
            case 422:
                throw new Exception('Validation error: ' . json_encode($error));
            default:
                throw new Exception('API error: ' . $response->body());
        }
    }
} catch (\Exception $e) {
    // Handle exception
    logger()->error('SevDesk API error: ' . $e->getMessage());
}

Common Patterns

Pagination

Most list endpoints support pagination:

$limit = 50;
$offset = 0;

do {
    $response = $sevdesk->contact()->getContacts('1', null);
    // Note: The SDK's getContacts method doesn't support limit/offset parameters directly
    // You would need to modify the request or use the raw API
    
    $contacts = $response->json('objects') ?? [];
    
    // Process contacts
    foreach ($contacts as $contact) {
        // Process each contact
    }
    
    $offset += $limit;
} while (count($contacts) >= $limit);

Filtering and Searching

Many endpoints support filtering through query parameters:

// Search contacts by various criteria
// Note: These would require custom requests as the SDK methods have limited parameters
$request = new \Saloon\Http\Request();
$request->setMethod('GET');
$request->setEndpoint('/Contact');
$request->query()->add([
    'depth' => 1,
    'name' => 'ACME',     // Search by name
    'email' => '@acme.com', // Search by email
    'limit' => 100,
]);
$response = $sevdesk->send($request);

Working with Enums

The package includes various enum classes for type-safe values:

use Ameax\SevDeskApi\Enums\Status\InvoiceStatus;
use Ameax\SevDeskApi\Enums\Type\InvoiceType;
use Ameax\SevDeskApi\Enums\ObjectName;

// Use enum values
$status = InvoiceStatus::DRAFT; // 100
$type = InvoiceType::INVOICE; // 'RE'
$objectName = ObjectName::CONTACT; // 'Contact'

Troubleshooting

Common Issues

1. Authentication Error (401)

   • Verify your API token is correct
   • Check if the token has been regenerated in SevDesk
   • Ensure the token is exactly 32 characters

2. Not Found Error (404)

   • Check if the resource ID exists
   • Verify you're using the correct endpoint
   • Some resources may have been deleted

3. Validation Error (422)

   • Check required fields are provided
   • Verify data types match API expectations
   • Review the error response for specific field errors

4. Timeout Errors

   • Increase the timeout in configuration
   • Check your network connection
   • SevDesk API might be experiencing high load

Debug Mode

Enable debug mode to see detailed request/response information:

// For Saloon v3, you can add middleware or use Laravel's HTTP client debugging
$sevdesk->getConfig('debug', true);

Limitations

• The current version of the SDK has limited support for request body parameters in some update methods
• Some endpoints may require custom requests for advanced filtering
• Bulk operations are not directly supported by all resources
