​
Webhook Endpoint

You should configure your webhook endpoint to receive POST requests from Propaga. The webhook will send the transaction confirmation data in JSON format. Please contact us to set up the webhook.

​
Payload Structure

Here’s an example of the webhook payload you’ll receive: 
{
  "transactionId": "671f75a4-f145-4f4b-82ff-4eaf0fd1e5aa",
  "cornerStoreId": "57b9d911-1c6e-45c0-be98-bfaeec8d9cf8",
  "wholesalerTransactionId": "bd0880c6-45a7-4998-b30f-65f91f28956d",
  "totalAmount": 1000,
  "interest": 200,
  "totalAmountWithInterest": 1200,
  "movementDate": "2024-01-01T00:00:00Z",
  "status": "on-hold"
}

​

Handling the Webhook

Here’s an example of how to handle the webhook in different programming languages: 
app.post('/webhook/transaction-confirmation', async (req, res) => {
  try {
    const transactionConfirmation = req.body;
    
    // Process the paid transaction notification data
    await processTransactionConfirmation(transactionConfirmation);
    
    // Respond with success
    res.status(200).json({ status: 'success' });
  } catch (error) {
    console.error('Error processing transaction confirmation:', error);
    res.status(500).json({ status: 'error', message: error.message });
  }
});

async function processTransactionConfirmation(transactionConfirmation) {
  // Validate the transaction confirmation
  console.log(`Processing transaction confirmation: ${transactionConfirmation.id}`);
  console.log(`Status: ${transactionConfirmation.status}`);
  
  // Process each transaction
  console.log(`Transaction ID: ${transactionConfirmation.transactionId}`);
  console.log(`Corner Store ID: ${transactionConfirmation.cornerStoreId}`);
  console.log(`Wholesaler Transaction ID: ${transactionConfirmation.wholesalerTransactionId}`);
  console.log(`Total Amount: ${transactionConfirmation.totalAmount}`);
  console.log(`Interest: ${transactionConfirmation.interest}`);
  console.log(`Total Amount With Interest: ${transactionConfirmation.totalAmountWithInterest}`);
  console.log(`Movement Date: ${transactionConfirmation.movementDate}`);
  console.log(`Status: ${transactionConfirmation.status}`);
}

Best Practices

  1. Verify the Webhook Source: Implement security measures to verify that the webhook is coming from Propaga.
  2. Implement Idempotency: Store the referenceNumber to avoid processing the same conciliation multiple times.
  3. Handle Errors Gracefully: Implement proper error handling and logging to track any issues with webhook processing.
  4. Respond Quickly: Your webhook endpoint should respond as quickly as possible. If processing takes time, handle it asynchronously.
  5. Validate Data: Always validate the incoming data before processing it.
