About this template

This app uses the Stripe API to create payment methods for users. It includes a Flask web service with an endpoint to create a payment method. The backend makes an API call to create the payment method using the Stripe API. The app displays the payment method ID in an alert after submission. The app allows for the use of test tokens to create payment methods using test cards.

Introduction to the Create Payment Method with Stripe API Template

Welcome to the Create Payment Method with Stripe API template! This template is designed to help you integrate Stripe's payment method creation functionality into your application. It provides a simple Flask web service with an endpoint that interacts with the Stripe API to create payment methods for users. The template includes a frontend HTML form that allows users to trigger the creation of a payment method and displays the result. This step-by-step guide will walk you through using this template on the Lazy platform.

Clicking Start with this Template

To begin using this template, click on the "Start with this Template" button. This will pre-populate the code in the Lazy Builder interface, so you won't need to copy, paste, or delete any code manually.

Initial setup: Adding Environment Secrets

Before you can test and use the app, you'll need to set up an environment secret for the Stripe API key. Here's how to do it:

  • Log in to your Stripe account and navigate to the API keys section.
  • Copy your secret API key. Remember to use a test key if you're working in a development environment.
  • In the Lazy Builder interface, go to the Environment Secrets tab.
  • Create a new secret with the key STRIPE_API_KEY and paste your Stripe secret API key as the value.

With the environment secret set, the app will be able to authenticate with Stripe's API.

Test: Pressing the Test Button

Once you have set up the environment secret, press the "Test" button. This will begin the deployment of the app and launch the Lazy CLI. The app will be deployed on the Lazy platform, and you won't need to worry about installing libraries or setting up your environment.

Using the App

After pressing the "Test" button, Lazy will provide you with a dedicated server link. Use this link to access the app's frontend interface. Here's how to interact with the frontend:

  • Open the provided server link in your web browser.
  • You will see a button labeled "Create Payment Method" on the webpage.
  • Click this button to initiate the creation of a Stripe payment method using a test token.
  • The result will be displayed on the page, showing whether the payment method was created successfully or if there was an error.

This interface allows you to test the payment method creation process without writing any additional code.

Integrating the App

If you want to integrate this functionality into another service or frontend, you can use the provided server link as the endpoint for creating payment methods. Ensure that you handle the API responses correctly in your integration.

Here's a sample request you might make to the app's API:


POST /create_payment_method
Content-Type: application/json

{
  "token": "tok_visa"
}

And here's a sample response you might receive:


{
  "id": "pm_1ExampleID",
  "object": "payment_method",
  // ... other payment method details ...
}

Remember to replace tok_visa with the actual token you receive from Stripe.js in your production environment.

By following these steps, you can easily use the Create Payment Method with Stripe API template on the Lazy platform to add payment method creation capabilities to your application.
