​
Balance Batch Completion Webhook

When batch processing completes, a notification will be sent to the webhook_url specified in the /v1/balance_requests endpoint.
Important Considerations:
  • Webhook delivery is not guaranteed
  • Webhooks will be retried for up to 30 minutes with exponential backoff
  • If delivery fails after 30 minutes, no further retries will occur
  • Always implement polling as a fallback mechanism

​
Webhook Response

Your webhook endpoint should respond with an HTTP 2xx status code to confirm receipt: 
{
  "status": "received"
}
If a 2xx response is not received, the webhook will be retried with exponential backoff for up to 30 minutes.

​
Implementing a Webhook Endpoint

Here are examples of implementing a webhook endpoint in various languages: 
from flask import Flask, request, jsonify
import logging

app = Flask(__name__)

@app.route('/webhook/balance-batch-complete', methods=['POST'])
def handle_balance_webhook():
    try:
        # Parse the webhook payload
        data = request.get_json()
        
        # Validate required fields
        if not all(k in data for k in ['event_uuid', 'type', 'batch_id']):
            return jsonify({'error': 'Missing required fields'}), 400
        
        # Verify the event type
        if data['type'] != 'BALANCE_BATCH_COMPLETED':
            return jsonify({'error': 'Unexpected event type'}), 400
        
        # Log the event
        logging.info(f"Balance batch completed: {data['batch_id']}")
        
        # Process the completed batch (fetch results, update database, etc.)
        process_completed_batch(data['batch_id'])
        
        # Return success response
        return jsonify({'status': 'received'}), 200
        
    except Exception as e:
        logging.error(f"Webhook processing error: {str(e)}")
        return jsonify({'error': 'Internal server error'}), 500

def process_completed_batch(batch_id):
    # Fetch balance results using the batch_id
    # Update your database
    # Trigger any downstream processes
    pass

​
Retry Mechanism

The webhook delivery system implements exponential backoff:
  1. Initial attempt - Immediate
  2. First retry - After 1 minute
  3. Second retry - After 2 minutes
  4. Third retry - After 4 minutes
  5. Subsequent retries - Doubling interval up to 30 minutes total
After 30 minutes, no further retry attempts will be made.

​
Security Considerations

To secure your webhook endpoint:
  1. Use HTTPS - Always use SSL/TLS encryption for your webhook endpoint
  2. Validate payloads - Check that all required fields are present
  3. Implement idempotency - Handle duplicate webhook deliveries gracefully
  4. Add authentication - Consider implementing webhook signatures or API keys
  5. Rate limiting - Protect against potential abuse

​
Fallback Strategy

Since webhook delivery is not guaranteed, implement a polling fallback: 
import time
import requests

def wait_for_batch_completion(batch_id, api_key, max_wait=3600):
    """
    Poll for batch completion with exponential backoff
    """
    start_time = time.time()
    poll_interval = 30  # Start with 30 seconds
    
    while time.time() - start_time < max_wait:
        # Check if batch is complete
        response = requests.get(
            f"https://api.rightfoot.com/v1/balances?batchId={batch_id}&limit=1",
            headers={"Authorization": f"Bearer {api_key}"}
        )
        
        if response.status_code == 200:
            # Batch is complete
            return True
        elif response.status_code == 404:
            # Batch still processing
            time.sleep(poll_interval)
            poll_interval = min(poll_interval * 1.5, 300)  # Cap at 5 minutes
        else:
            # Handle error
            raise Exception(f"Error checking batch status: {response.status_code}")
    
    return False  # Timeout reached

​
Best Practices

  1. Always implement polling - Don’t rely solely on webhooks
  2. Handle duplicates - Your system should be idempotent
  3. Log all events - Keep an audit trail of webhook receipts
  4. Monitor failures - Set up alerts for webhook processing errors
  5. Process asynchronously - Return 200 quickly and process in the background

Body

application/json
​
event_uuid
string
required

type
string
required

The type of the webhook event, typically BALANCE_BATCH_COMPLETED.

Example:

"BALANCE_BATCH_COMPLETED"

​
batch_id
