Introduction to the Stripe Default Payment Method Template
Welcome to the Stripe Default Payment Method Template! This template is designed to help you integrate a simple web application that uses the Stripe API to set a default payment method for customers. It's built with Flask, a lightweight web framework for Python, and includes a user-friendly interface for inputting customer and payment method IDs. This guide will walk you through the steps to get this template up and running on the Lazy platform.
Getting Started
To begin using this template, 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.
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. Here's how to do it:
- 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.
- Create a new secret with the key
STRIPE_API_KEYand paste your Stripe API key as the value.
Test: Pressing the Test Button
Once you have set up your environment secret, press the "Test" button on the Lazy platform. This will deploy your application and launch the Lazy CLI.
Using the App
After pressing the "Test" button, Lazy will provide you with a dedicated server link to use the web interface. Navigate to this link in your web browser to access the application's frontend.
Here's how to use the interface:
- Enter the Customer ID for the Stripe customer whose default payment method you want to set.
- Enter the Payment Method ID that you want to set as the default for the customer.
- Click the "Set Default Payment Method" button to submit the form.
- The application will process your request and display a message indicating whether the default payment method was set successfully or if there was an error.
Integrating the App
If you want to integrate this functionality into another service or frontend, you can use the provided server link to make API calls to the /set_default_payment_method endpoint. Here's a sample request you might make to the endpoint:
`POST /set_default_payment_method
Content-Type: application/json
{
"customer": "cus_xxxxxxxxxxxxx",
"payment_method": "pm_xxxxxxxxxxxxx"
}`
And here's a sample response you might receive:
{
"message": "Default payment method set successfully."
}
If you need to integrate this app into an external tool, you may need to add the app's server link provided by Lazy to that tool. Ensure you follow the specific integration steps required by the external tool, such as setting the correct scopes or adding the API endpoint in the tool's configuration.
By following these steps, you should now have a fully functional application that can set a default payment method for Stripe customers using the Lazy platform.
