Stripe Webhook FastAPI Test Sender
This video demonstrates how to use the Stripe Webhook FastAPI Test Sender template.
from fastapi import FastAPI
from pydantic import BaseModel
import logging
import uvicorn
app = FastAPI()
logging.basicConfig(level=logging.INFO)
class Item(BaseModel):
data: dict
@app.post("/webhook")
async def stripe_webhook(item: Item):
logging.info('Received Stripe webhook: %s', item.data)
return {"Received": "OK"}
if __name__ == "__main__":
uvicorn.run(app, host="0.0.0.0", port=8080)Frequently Asked Questions
What is the purpose of the Stripe Webhook Test Sender?
The Stripe Webhook Test Sender is designed to simulate and test webhook events from the Stripe API. It allows developers to send mock webhook data and observe how their application handles these events. This tool is crucial for testing and debugging Stripe integrations without the need to trigger real events in a production environment.
How can businesses benefit from using this Stripe Webhook Test Sender?
Businesses can greatly benefit from this tool in several ways: - It allows for thorough testing of payment workflows without risking real transactions. - Developers can simulate various Stripe events (like successful payments, failed charges, or subscription updates) to ensure the application responds correctly. - It helps in identifying and fixing potential issues before deploying to a live environment, reducing the risk of payment processing errors.
Can the Stripe Webhook Test Sender be integrated into our existing development workflow?
Yes, the Stripe Webhook Test Sender can be easily integrated into existing development workflows. It's built using FastAPI, which makes it lightweight and easy to run alongside other development tools. Developers can incorporate it into their continuous integration pipelines or use it for local testing during development to ensure that Stripe webhook handling is functioning correctly before pushing code to production.
How can I modify the Stripe Webhook Test Sender to handle specific Stripe event types?
You can modify the Stripe Webhook Test Sender to handle specific event types by updating the /webhook endpoint. Here's an example of how you might modify the code to handle different event types:
python
@app.post("/webhook")
async def stripe_webhook(item: Item):
event_type = item.data.get('type')
if event_type == 'payment_intent.succeeded':
# Handle successful payment
logging.info('Payment succeeded: %s', item.data)
elif event_type == 'payment_intent.payment_failed':
# Handle failed payment
logging.info('Payment failed: %s', item.data)
else:
# Handle other event types
logging.info('Received event: %s', event_type)
return {"Received": "OK"}
This modification allows the Stripe Webhook Test Sender to process different types of Stripe events and perform specific actions based on the event type.
How can I enhance the security of the Stripe Webhook Test Sender?
To enhance the security of the Stripe Webhook Test Sender, you can implement Stripe's webhook signature verification. This ensures that the incoming webhooks are actually from Stripe. Here's an example of how you can modify the code to include this:
```python from fastapi import FastAPI, Header, HTTPException import stripe
app = FastAPI() stripe.api_key = "your_stripe_secret_key" endpoint_secret = "your_webhook_signing_secret"
@app.post("/webhook") async def stripe_webhook(item: Item, stripe_signature: str = Header(None)): try: event = stripe.Webhook.construct_event( payload=item.json(), sig_header=stripe_signature, secret=endpoint_secret ) except ValueError as e: raise HTTPException(status_code=400, detail="Invalid payload") except stripe.error.SignatureVerificationError as e: raise HTTPException(status_code=400, detail="Invalid signature")
# Process the event
logging.info('Verified Stripe webhook: %s', event)
return {"Received": "OK"}
```
This modification adds signature verification to the Stripe Webhook Test Sender, ensuring that only legitimate Stripe webhooks are processed.

Introduction to the Stripe Webhook Test Sender Template
Welcome to the Stripe Webhook Test Sender template! This template is designed to help you easily set up a server that listens for webhooks from Stripe. It's perfect for testing and confirming that your Stripe webhook integration is working correctly. The server will log the data received from Stripe, allowing you to verify the webhook's payload and ensure your application processes it as expected.
Getting Started
To begin using this template, simply click on "Start with this Template" on the Lazy platform. This will pre-populate the code in the Lazy Builder interface, so you won't need to copy, paste, or delete any code manually.
Test: Pressing the Test Button
Once you have started with the template, the next step is to test the application. Press the "Test" button on the Lazy platform. This will deploy your app and launch the Lazy CLI. There is no need for user input at this stage, as the webhook endpoint is ready to receive data without further configuration.
Using the App
After pressing the "Test" button, Lazy will provide you with a dedicated server link. This is the URL you will use to set up your Stripe webhook endpoint. Additionally, since this template uses FastAPI, Lazy will also provide a link to the automatically generated documentation for your API, which can be accessed to understand the available endpoints and their specifications.
To use the app:
- Copy the server link provided by Lazy.
- Go to your Stripe Dashboard and navigate to the Webhooks settings.
- Click on "Add endpoint" and paste the server link into the "Endpoint URL" field.
- Select the events you want to receive and save the webhook.
- Stripe will send a test webhook to the provided URL, which your app will receive and log.
Check the Lazy CLI for the log output to see the data received from Stripe. This confirms that your webhook is set up correctly and that your server is receiving data as expected.
Integrating the App
If you wish to integrate this webhook listener into a larger system or a frontend application, you can use the server link as the endpoint for Stripe webhook events. Ensure that any system that needs to process these events is configured to listen to the logs or to perform actions based on the data received.
For example, if you have a frontend application that needs to update the user interface based on a successful payment event, you would:
- Set up an event listener in your frontend application that listens for logs from your webhook server.
- When a new log is received indicating a successful payment, trigger the necessary UI update.
Remember, the Lazy platform handles all the deployment details, so you can focus on integrating and using the application within your software ecosystem.
