​
Webhook Endpoint

You should configure your webhook endpoint to receive POST requests from Propaga. The webhook will send the user KYC finished 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 when the user finishes the KYC process: 
{
  "userId": "671f75a4-f145-4f4b-82ff-4eaf0fd1e5aa",
  "cornerStoreId": "57b9d911-1c6e-45c0-be98-bfaeec8d9cf8",
  "externalId": "123456789",
  "kycStatus": "completed"
}

​
Payload Fields

FieldTypeDescription
userIdStringThe Propaga’s ID of the user.
cornerStoreIdStringThe ID of the corner store.
externalIdStringThe ID of the user in your system.
kycStatusStringThe status of the KYC process.

​
Handling the Webhook

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

async function processUserKYCFinishedNotification(userKYCFinishedNotification) {
  // Validate the user KYC finished notification
  console.log(`Processing user KYC finished notification: ${userKYCFinishedNotification.id}`);
  console.log(`Status: ${userKYCFinishedNotification.kycStatus}`);
  
  // Process the user KYC finished notification
  console.log(`User ID: ${userKYCFinishedNotification.userId}`);
  console.log(`External ID: ${userKYCFinishedNotification.externalId}`);
}

Best Practices

  1. Verify the Webhook Source: Implement security measures to verify that the webhook is coming from Propaga.
  2. Implement Idempotency: Store the userId to avoid processing the same user KYC finished notification 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.
