About this template

This app template will create and retrieve a payment intent on Stripe using API. It requires the Stripe API key to be set as an environment variable named 'STRIPE_API_KEY'. The template provides a POST endpoint at '/create_payment_intent' to create a payment intent and a GET endpoint at '/retrieve_payment_intent/{payment_intent_id}' to retrieve a payment intent.

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.

  1. Log in to your Stripe account and navigate to the API keys section.
  2. Copy your Stripe API key. If you don't have one, you'll need to create it.
  3. Go to the Environment Secrets tab within the Lazy Builder interface.
  4. Create a new secret with the key STRIPE_API_KEY and 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.
