@app.post("/create_payment_intent")
def create_payment_intent(payment_intent: PaymentIntent):
intent = stripe.PaymentIntent.create(
amount=payment_intent.amount,

What is the main purpose of this Create Stripe Payment Intent with API template?
The main purpose of this template is to provide a simple and efficient way to create and retrieve Stripe Payment Intents using a FastAPI application. It allows businesses to easily integrate Stripe payment processing into their applications, enabling them to accept card payments securely.
How can this template benefit e-commerce businesses?
The Create Stripe Payment Intent with API template can greatly benefit e-commerce businesses by: - Streamlining the payment process for customers - Providing a secure way to handle card payments - Allowing for easy integration with existing e-commerce platforms - Enabling businesses to track and manage payment intents efficiently
Can this template be used for subscription-based services?
While this template is primarily designed for one-time payments, it can be adapted for subscription-based services. You would need to modify the template to create recurring payment intents or integrate it with Stripe's Subscription API. The core functionality of creating and retrieving payment intents can still be utilized for subscription-based services.
How can I modify the template to accept payments in different currencies?
To accept payments in different currencies, you can modify the create_payment_intent function in the template. Here's an example of how you can update the function to accept a currency parameter:
```python class PaymentIntent(BaseModel): amount: int currency: str
@app.post("/create_payment_intent") def create_payment_intent(payment_intent: PaymentIntent): intent = stripe.PaymentIntent.create( amount=payment_intent.amount, currency=payment_intent.currency, payment_method_types=['card'], ) return intent ```
This modification allows you to specify the currency when creating a payment intent, making the Create Stripe Payment Intent with API template more versatile for international businesses.
How can I add error handling to the template?
To add error handling to the Create Stripe Payment Intent with API template, you can use FastAPI's built-in exception handling along with Stripe's error types. Here's an example of how you can modify the create_payment_intent function to include error handling:
```python from fastapi import HTTPException import stripe
@app.post("/create_payment_intent") def create_payment_intent(payment_intent: PaymentIntent): try: intent = stripe.PaymentIntent.create( amount=payment_intent.amount, currency='usd', payment_method_types=['card'], ) return intent except stripe.error.CardError as e: raise HTTPException(status_code=400, detail=str(e)) except stripe.error.StripeError as e: raise HTTPException(status_code=500, detail=str(e)) ```
This modification catches Stripe-specific errors and raises appropriate HTTP exceptions, allowing for better error handling and reporting in your application.

Introduction to the Create Stripe Payment Intent with API Template
Welcome to the Create Stripe Payment Intent with API template! This template is designed to help you integrate Stripe payment processing into your application with ease. By using this template, you can quickly set up endpoints to create and retrieve payment intents, which are essential for handling secure online transactions. Whether you're building an e-commerce platform, a subscription service, or any other application that requires payment processing, this template will streamline the process for you.
Clicking Start with this Template
To begin using this template, simply click on the "Start with this Template" button. This will initialize the template within the Lazy platform, allowing you to customize and deploy your application without worrying about code setup or environment configuration.
Initial Setup: Adding Environment Secrets
Before you can test and use the application, you need to set up an environment secret for the Stripe API key. This is a crucial step as it allows your application to authenticate with Stripe's services.
- Log in to your Stripe account and navigate to the API keys section.
- Copy your Stripe API key. If you don't have one, you'll need to create it.
- Go to the Environment Secrets tab within the Lazy Builder interface.
- Create a new secret with the key
STRIPE_API_KEYand paste your Stripe API key as the value.
With the Stripe API key securely stored, your application will be able to communicate with Stripe to process payments.
Test: Pressing the Test Button
Once you have set up the environment secret, press the "Test" button to deploy your application. The Lazy platform will handle the deployment process, and you won't need to install any libraries or set up your environment manually.
Using the App
After pressing the "Test" button, the Lazy CLI will provide you with a dedicated server link to use the API. Additionally, since this template uses FastAPI, you will also receive a link to the automatically generated documentation for your API endpoints.
To create a payment intent, you will use the POST endpoint at /create_payment_intent. Here's a sample request you might send to this endpoint:
{
"amount": 1000
}
This request will create a payment intent for $10.00 (since Stripe uses the smallest currency unit, in this case, cents).
Here's a sample response you might receive:
{
"id": "pi_1F4ACM2eZvKYlo2C3Ktj4a4b",
"object": "payment_intent",
"amount": 1000,
// ... other payment intent details
}
To retrieve a payment intent, you will use the GET endpoint at /retrieve_payment_intent/{payment_intent_id}, replacing {payment_intent_id} with the actual ID of the payment intent you wish to retrieve.
Integrating the App
After successfully creating and retrieving payment intents using the provided endpoints, you may want to integrate this functionality into your frontend or another service. To do this, you will need to make HTTP requests to the server link provided by the Lazy CLI.
If your application has a frontend, you can use JavaScript to send requests to these endpoints. Here's an example of how you might do this:
fetch('YOUR_SERVER_LINK/create_payment_intent', {
method: 'POST',
headers: {
'Content-Type': 'application/json'
},
body: JSON.stringify({
amount: 1000
})
})
.then(response => response.json())
.then(data => console.log(data))
.catch((error) => console.error('Error:', error));
Replace YOUR_SERVER_LINK with the server link provided by the Lazy CLI. This code would be used to create a new payment intent from your frontend application.
By following these steps, you can leverage the Create Stripe Payment Intent with API template to add robust payment processing capabilities to your application, all within the Lazy platform.
