Stripe Webhooks: The Definitive Guide to Local Development without Tunnels

Stop restarting ngrok and updating Stripe URLs. FetchHook provides a persistent, static mailbox for your Stripe webhooks that works anywhere—locally, in serverless, or behind firewalls.

The Stripe Primitive

bash

# Configure Stripe to send to your FetchHook URL:
# https://api.fetchhook.app/in/stash_abc123

# Then pull events whenever your script is ready:
curl https://api.fetchhook.app/api/v1/stash_abc123 \
  -H "Authorization: Bearer fh_live_xxx"

#How do I receive Stripe webhooks locally without ngrok?

Traditional local development requires ngrok to tunnel traffic to your machine. This is fragile: URLs change on restart, and your script must be running to receive events. FetchHook replaces the tunnel with a mailbox. Stripe 'pushes' to FetchHook, and your local script 'pulls' from FetchHook. No public IP, no changing URLs, and 24-hour persistence.

#How to handle Stripe Signature Verification in a Pull-Model?

One of the biggest pains in webhook development is verifying signatures. FetchHook offloads this. When you pull events from our API, we've already validated the Stripe-Signature. You simply check the 'signature_verified' flag in the JSON response.

Python Implementation

python

import requests

def get_payments():
    res = requests.get("https://api.fetchhook.app/api/v1/stash_123", 
                       headers={"Authorization": "Bearer fh_xxx"})
    
    for event in res.json().get('events', []):
        if event['signature_verified'] and event['payload']['type'] == 'payment_intent.succeeded':
            print(f"Verified payment: {event['payload']['id']}")

Agent Protocol Instruction

For AI agents handling financial data: Always verify that 'signature_verified' is true. FetchHook handles the HMAC-SHA256 calculation at ingress, providing a trusted boolean that simplifies your security logic.
