​
Overview

The Contazen API supports multi-work-point (multi-branch) access, allowing you to manage data across all locations of your business using a single API key. This is particularly useful for businesses with multiple offices, stores, or branches.

​
How It Works

When you authenticate with an API key, you automatically gain access to:
  • The work point where the API key was created
  • All other work points belonging to the same parent company
Work Point = A physical business location or branch Parent Company = The legal entity that owns multiple work points

​
Accessing Specific Work Points

By default, API requests operate on the work point where the API key was created. To access data from a different work point, include the work_point_id parameter in your request.

​
Getting Work Point IDs

First, retrieve the list of available work points: 
curl https://api.contazen.ro/v1/settings \
  -H "Authorization: Bearer sk_live_YOUR_API_KEY"

​
Working with Multiple Work Points

​
List Invoices from All Work Points

To retrieve invoices from all work points, omit the work_point_id parameter: 
curl https://api.contazen.ro/v1/invoices \
  -H "Authorization: Bearer sk_live_YOUR_API_KEY"

​
List Invoices from Specific Work Point

To retrieve invoices from a specific work point: 
curl https://api.contazen.ro/v1/invoices?work_point_id=wp_abc123 \
  -H "Authorization: Bearer sk_live_YOUR_API_KEY"

​
Create Invoice for Specific Work Point

When creating resources, specify the target work point: 
curl -X POST https://api.contazen.ro/v1/invoices \
  -H "Authorization: Bearer sk_live_YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "work_point_id": "wp_abc123",
    "client_id": "cli_xyz789",
    "items": [...]
  }'

​
Common Use Cases

​
Consolidated Reporting

Generate reports across all business locations: 
async function getConsolidatedRevenue(apiKey, startDate, endDate) {
  const response = await fetch('https://api.contazen.ro/v1/invoices', {
    headers: {
      'Authorization': `Bearer ${apiKey}`
    }
  });
  
  const invoices = await response.json();
  
  // Group by work point
  const revenueByLocation = {};
  invoices.data.forEach(invoice => {
    const wpId = invoice.work_point_id;
    if (!revenueByLocation[wpId]) {
      revenueByLocation[wpId] = 0;
    }
    revenueByLocation[wpId] += invoice.total;
  });
  
  return revenueByLocation;
}

​
Centralized Client Management

Share client data across all locations: 
async function findClientAcrossAllLocations(apiKey, searchTerm) {
  const response = await fetch(
    `https://api.contazen.ro/v1/clients?search=${searchTerm}`,
    {
      headers: {
        'Authorization': `Bearer ${apiKey}`
      }
    }
  );
  
  const clients = await response.json();
  return clients.data; // Returns clients from all work points
}

​
Location-Specific Operations

Process operations for a specific branch: 
class BranchManager {
  constructor(apiKey, workPointId) {
    this.apiKey = apiKey;
    this.workPointId = workPointId;
  }
  
  async createInvoice(clientId, items) {
    const response = await fetch('https://api.contazen.ro/v1/invoices', {
      method: 'POST',
      headers: {
        'Authorization': `Bearer ${this.apiKey}`,
        'Content-Type': 'application/json'
      },
      body: JSON.stringify({
        work_point_id: this.workPointId,
        client_id: clientId,
        items: items
      })
    });
    
    return response.json();
  }
  
  async getProducts() {
    const response = await fetch(
      `https://api.contazen.ro/v1/products?work_point_id=${this.workPointId}`,
      {
        headers: {
          'Authorization': `Bearer ${this.apiKey}`
        }
      }
    );
    
    return response.json();
  }
}

// Usage
const bucharest = new BranchManager('sk_live_KEY', 'wp_bucharest');
const cluj = new BranchManager('sk_live_KEY', 'wp_cluj');

​
Best Practices

Configure a default work point in your SDK client to avoid specifying it for every request:
$client = Contazen\Client::create('sk_live_KEY')
    ->withWorkPointId('wp_default')
    ->build();
Work points don’t change frequently. Cache the list to reduce API calls:
let workPointCache = null;

async function getWorkPoints(apiKey) {
  if (!workPointCache) {
    const response = await fetch('https://api.contazen.ro/v1/settings', {
      headers: { 'Authorization': `Bearer ${apiKey}` }
    });
    const data = await response.json();
    workPointCache = data.work_points;
  }
  return workPointCache;
}
Always handle cases where a work point might not be accessible:
try {
  const invoice = await createInvoice(workPointId, data);
} catch (error) {
  if (error.code === 'work_point_not_found') {
    console.error('Work point not accessible or does not exist');
  }
}

​
Limitations

  • API keys can only access work points within the same parent company
  • Some operations may be restricted to specific work points based on permissions
  • Work point IDs are immutable and cannot be changed once created
