# Send Paid Transaction Notification

> This webhook is used when a transaction is paid by the user

## Webhook Endpoint

You should configure your webhook endpoint to receive POST requests from Propaga. The webhook will send the paid transaction notification 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:

```json theme={null}
{
  "transactionId": "671f75a4-f145-4f4b-82ff-4eaf0fd1e5aa",
  "cornerStoreId": "57b9d911-1c6e-45c0-be98-bfaeec8d9cf8",
  "wholesalerTransactionId": "bd0880c6-45a7-4998-b30f-65f91f28956d",
  "totalAmount": 1000,
  "interest": 200,
  "totalAmountWithInterest": 1200,
  "paidDate": "2024-01-01T00:00:00Z",
  "status": "paid"
}
```

## Handling the Webhook

Here's an example of how to handle the webhook in different programming languages:

<CodeGroup>
  ```javascript JavaScript theme={null}
  app.post('/webhook/paid-transaction-notification', async (req, res) => {
    try {
      const paidTransactionNotification = req.body;
      
      // Process the paid transaction notification data
      await processPaidTransactionNotification(paidTransactionNotification);
      
      // Respond with success
      res.status(200).json({ status: 'success' });
    } catch (error) {
      console.error('Error processing paid transaction notification:', error);
      res.status(500).json({ status: 'error', message: error.message });
    }
  });

  async function processPaidTransactionNotification(paidTransactionNotification) {
    // Validate the paid transaction notification
    console.log(`Processing paid transaction notification: ${paidTransactionNotification.id}`);
    console.log(`Status: ${paidTransactionNotification.status}`);
    
    // Process each transaction
    console.log(`Transaction ID: ${paidTransactionNotification.transactionId}`);
    console.log(`Corner Store ID: ${paidTransactionNotification.cornerStoreId}`);
    console.log(`Wholesaler Transaction ID: ${paidTransactionNotification.wholesalerTransactionId}`);
    console.log(`Total Amount: ${paidTransactionNotification.totalAmount}`);
    console.log(`Interest: ${paidTransactionNotification.interest}`);
    console.log(`Total Amount With Interest: ${paidTransactionNotification.totalAmountWithInterest}`);
    console.log(`Paid Date: ${paidTransactionNotification.paidDate}`);
    console.log(`Status: ${paidTransactionNotification.status}`);
  }
  ```

  ```python Python theme={null}
  from flask import Flask, request, jsonify

  app = Flask(__name__)

  @app.route('/webhook/credit-limit-update', methods=['POST'])
  def handle_credit_limit_update():
      try:
          paidTransactionNotification = request.json
          
          # Process the paid transaction notification data
          process_paid_transaction_notification(paidTransactionNotification)
          
          return jsonify({'status': 'success'}), 200
      except Exception as e:
          print(f'Error processing paid transaction notification: {str(e)}')
          return jsonify({'status': 'error', 'message': str(e)}), 500

  def process_paid_transaction_notification(paidTransactionNotification):
      # Validate the transfer amount
      print(f"Processing paid transaction notification: {paidTransactionNotification['id']}")
      
      # Process each transaction
      print(f"Transaction ID: {paidTransactionNotification['transactionId']}")
      print(f"Corner Store ID: {paidTransactionNotification['cornerStoreId']}")
      print(f"Wholesaler Transaction ID: {paidTransactionNotification['wholesalerTransactionId']}")
      print(f"Total Amount: {paidTransactionNotification['totalAmount']}")
      print(f"Interest: {paidTransactionNotification['interest']}")
      print(f"Total Amount With Interest: {paidTransactionNotification['totalAmountWithInterest']}")
      print(f"Paid Date: {paidTransactionNotification['paidDate']}")
      print(f"Status: {paidTransactionNotification['status']}")
  ```
</CodeGroup>

## 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.
