To get notified when a Stripe payment fails, add a webhook in your Stripe dashboard that points at your Hook.Notifier URL and select the payment_intent.payment_failed event. The failure shows up on your phone right away.
Set it up in the Stripe dashboard
No code needed. It takes a minute.
- In Hook.Notifier, go to Dashboard → Hooks and create a hook named Stripe. It gets its own URL and key, revocable anytime.
- In Stripe, go to Developers → Webhooks → Add endpoint and paste that URL as the endpoint.
- Select the events you care about:
payment_intent.payment_failedfor failed paymentsinvoice.payment_failedfor failed subscription renewalscheckout.session.completedfor new sales
- Save.
The next time a payment fails, your phone lights up.
First get your URL
Your Hook.Notifier URL is https://hooknotifier.com/{IDENTIFIER}/{KEY}. Create a free account to get yours, then paste it as the Stripe endpoint.
Turn the raw payload into a readable message
Stripe sends a full event payload. You do not need code or a middleman to shape it. On your hook's settings in the dashboard, define a payload template with paths resolved against the JSON Stripe posts.
For invoice.payment_failed (subscription renewals):
- objectTemplate:
Payment failed - bodyTemplate:
{{data.object.customer_email}} owes {{data.object.amount_due}} {{data.object.currency}}
The notification arrives already readable, no Zapier or webhook handler in between.
While you are on the hook's settings, set its defaults: tag payments so every Stripe event lands in its own colored folder, and priority high so a failed payment gets through even during your quiet hours.
Why it matters
A failed payment is often a card that expired or a subscriber about to churn. Catching it the moment it happens means you can reach out while it still counts, instead of finding out at the end of the month.
