Frequently Asked Questions
How can this Stripe Checkout integration benefit my Webflow-based business?
The Integration of Stripe Checkout Page in Webflow template offers several benefits for your business: - It allows you to easily accept payments directly on your Webflow site without redirecting customers to external pages. - You can set up both one-time payments and subscriptions, giving you flexibility in your pricing models. - The template captures UTM parameters, enabling you to track the effectiveness of your marketing campaigns in driving conversions. - It provides a seamless, professional checkout experience that can increase conversion rates.
Can I use this template for different types of products or services?
Yes, the Integration of Stripe Checkout Page in Webflow template is versatile and can be used for various products or services. Whether you're selling digital downloads, physical products, or subscription-based services, this template can be adapted to suit your needs. You just need to set up the appropriate product or price in your Stripe dashboard and update the PRICE
environment variable in the backend code.
How do I handle different subscription durations using this template?
The template currently sets up a subscription with a duration of one month. To handle different subscription durations, you can modify the create_checkout_session
function in the backend code. For example, you could add a duration
parameter to the Data
model and use it to determine the appropriate price ID:
```python class Data(BaseModel): duration: str # e.g., 'monthly', 'yearly' # ... other fields ...
@app.post('/create-checkout-session') def create_checkout_session(data: Data): # ... existing code ... price_id = MONTHLY_PRICE if data.duration == 'monthly' else YEARLY_PRICE session = stripe.checkout.Session.create( # ... other parameters ... line_items=[{'price': price_id, 'quantity': 1}], # ... rest of the function ... ) ```
You would then need to update the frontend code to send the chosen duration to the backend.
How can I customize the appearance of the checkout page?
The Integration of Stripe Checkout Page in Webflow template uses Stripe's embedded checkout, which provides a consistent and secure checkout experience. While the core appearance is determined by Stripe, you can customize some aspects through your Stripe dashboard. Go to Settings > Branding in your Stripe dashboard to update your brand color, logo, and icon. These changes will be reflected in the checkout page embedded in your Webflow site.
How do I handle successful payments and failed transactions using this template?
The template provides a foundation for handling both successful payments and failed transactions. For successful payments, you can customize the return_url
in the backend code to direct customers to a specific thank you page. For example:
python
return_url = YOUR_DOMAIN + '/thanks-for-payment?session_id={CHECKOUT_SESSION_ID}' + ('&' + utm_query if utm_query else '')
For failed transactions, Stripe handles the error display within the checkout interface. However, you can extend the template to include additional error handling. For instance, you could add a webhook endpoint to your backend that listens for payment_intent.payment_failed
events:
```python @app.post('/webhook') async def webhook_received(request: Request): payload = await request.body() sig_header = request.headers.get('stripe-signature')
try:
event = stripe.Webhook.construct_event(
payload, sig_header, STRIPE_WEBHOOK_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')
if event['type'] == 'payment_intent.payment_failed':
payment_intent = event['data']['object']
# Handle the failed payment, e.g., send an email to the customer
return {"success": True}
```
Remember to set up the webhook in your Stripe dashboard and update the STRIPE_WEBHOOK_SECRET
in your environment variables.

Introduction to the Stripe Checkout Session API Server Template
Welcome to the Stripe Checkout Session API Server template! This template is designed to help you integrate Stripe's payment processing capabilities into your Webflow project. With this template, you can create a custom payment flow that allows your customers to subscribe to your services or purchase your products with ease. Let's get started on setting up your Stripe Checkout Session API Server.
Getting Started
Click Start with this Template to begin using the Stripe Checkout Session API Server template on the Lazy platform. This will pre-populate the code in the Lazy Builder interface, so you won't need to copy or paste any code manually.
Initial Setup
Before you can test and use the app, you'll need to set up a few environment secrets within the Lazy Builder. These are crucial for the app to interact with Stripe and your Webflow site securely.
- STRIPE_SECRET_KEY: Your Stripe secret key, which you can find in your Stripe dashboard.
- YOUR_DOMAIN: The domain of your Webflow site where the payment page is hosted.
- PRICE: The price ID for the product or service you are offering, which you can create in your Stripe dashboard.
To set these up, navigate to the Environment Secrets tab within the Lazy Builder and add the above keys with their respective values.
Test
Press the Test button to deploy the app. The Lazy CLI will handle the deployment, and you won't need to install any libraries or set up your environment.
Entering Input
If the code requires user input, the Lazy App's CLI interface will prompt you to provide the necessary information after you press the test button. Follow the prompts to enter any required input.
Using the App
Once the app is deployed, Lazy will provide you with a dedicated server link to use the API. If the code uses FastAPI, you will also receive a link to the API documentation, which you can use to understand and interact with the available endpoints.
Integrating the App
To integrate the Stripe Checkout Session API Server with your Webflow project, follow these steps:
- Add the provided Stripe script to your Webflow payment page just before the
</body>
tag. - Replace
"Publishable stripe API key"
with your actual publishable API key from Stripe. - Replace
"URL TO ENPOINT YOUR PUBLISHED APP"
with the endpoint URL of your published app provided by Lazy.
Here's the sample code you'll need to add to your Webflow site:
`
` For more detailed instructions and advanced configurations, refer to the Stripe Custom Payment Flow documentation at Stripe Quickstart Guide.
Remember, it's crucial to ensure all keys and sensitive data are securely stored and your implementation complies with Stripe’s security standards.
