Heartfly

Monitor Stripe Webhook Processing for SaaS Billing

Ensure your SaaS billing processes remain uninterrupted by proactively monitoring critical Stripe webhook events. Get instant alerts if subscription updates, failed payments, or invoice generation stop firing.

The problem

Your SaaS relies heavily on Stripe webhooks to manage subscriptions, process payments, and update customer statuses. A silent failure in your webhook handler means missed renewals, incorrect billing, and frustrated customers, directly impacting your revenue. Debugging these issues post-mortem requires digging through logs and manually reconciling data, a time-consuming and error-prone process that can lead to significant financial discrepancies.

Imagine a scenario where your `invoice.payment_failed` webhook stops being processed due to a transient bug or a deployment issue. Your automated dunning sequences won't trigger, customers won't be notified, and you'll accumulate a growing list of unpaid invoices without realizing it. This often goes unnoticed until customer complaints or month-end reconciliation, by which point the damage to your revenue and customer trust is already substantial.

How Heartfly solves it

1
Set up Heartfly checks for each critical Stripe webhook, ensuring your billing engine always responds.
2
Receive immediate alerts via Slack or email when a webhook handler fails to ping Heartfly on time.
3
Gain peace of mind knowing your revenue-critical subscription updates are continuously monitored for silence.

Concrete example

import requests
import os

def handle_stripe_webhook(event_payload):
    # ... process Stripe event ...
    if event_payload.type == 'invoice.payment_succeeded':
        # After successful processing, ping Heartfly
        try:
            requests.get(os.getenv("HEARTFLY_PING_URL_INVOICE_SUCCESS"))
        except requests.exceptions.RequestException as e:
            print(f"Heartfly ping failed: {e}")

Frequently asked questions

How does Heartfly detect a failed Stripe webhook handler?
Heartfly monitors for the absence of a regular "ping" from your webhook handler. If your script successfully processes an event but then fails to send its configured Heartfly ping within its expected interval, Heartfly sends an alert.
Can I monitor different Stripe webhook types separately?
Yes, you can configure a unique Heartfly check for each critical Stripe webhook event type (e.g., `invoice.payment_succeeded`, `customer.subscription.updated`). This allows granular monitoring and specific alerts for different billing workflows.
What alert channels are supported for Stripe webhook monitoring?
Heartfly supports various alert channels including email, Slack, PagerDuty, webhooks, and more. You can customize who receives alerts based on the criticality of each Stripe webhook failure.
