Remember: each call uses the API key of the corresponding fiscal entity (professional vs marketplace).

1. 1

   Customer books a service on your platform

   Your app records the transaction with customer, professional and breakdown. You calculate your commission per your model and store IDs for customer, professional and order.

2. 2

   The payment gateway confirms the charge

   Stripe, PayPal or your processor fires the successful payment webhook. Your backend verifies the signature, marks the order as paid and prepares the data for both invoices.

   Node.js

   import express from 'express';
   import { WebhookVerifier } from '@beel_es/sdk';
   
   const verifier = new WebhookVerifier(process.env.BEEL_WEBHOOK_SECRET!);
   
   app.post(
     '/webhooks/beel',
     express.raw({ type: 'application/json' }),
     (req, res) => {
       try {
         const event = verifier.verify(
           req.body.toString('utf8'),
           req.headers['beel-signature'] as string,
         );
   
         // event.type is one of:
         //   'invoice.emitted' | 'invoice.email.sent'
         //   'invoice.cancelled' | 'verifactu.status.updated'
         if (event.type === 'verifactu.status.updated') {
           console.log(event.data.new_status); // 'ACCEPTED' | 'REJECTED'
         }
   
         res.status(200).send('OK');
       } catch {
         res.status(400).send('Invalid signature');
       }
     },
   );

3. 3

   Both invoices are generated automatically

   One invoice from the professional to the end customer for the service. Another from the marketplace to the professional for the commission. Each company uses its own API key — BeeL. issues both in parallel.

   Node.js

   import { BeeL } from '@beel_es/sdk';
   
   const beel = new BeeL({ apiKey: process.env.BEEL_API_KEY! });
   
   // Create a draft invoice
   const invoice = await beel.invoices.create({
     type: 'STANDARD',
     recipient: { customer_id: '550e8400-e29b-41d4-a716-446655440000' },
     lines: [
       { description: 'Monthly subscription', quantity: 1, unit_price: 29.00, discount_percentage: 0 },
     ],
   });
   
   // Issue it to assign an invoice number and trigger VeriFactu
   const issued = await beel.invoices.issue(invoice.id);
   console.log(issued.invoice_number); // e.g. "A-2026/0001"

4. 4

   PDFs delivered automatically

   BeeL. emails both PDFs: the customer gets the service invoice, the professional gets the commission invoice. Sequential numbering and Verifactu QR on both.

5. 5
