Stripe Payment Integration

Codepup AI makes it easy to add real payment processing to your website using Stripe. You can set it up right from the beginning when creating your project, or add it later at any time through the chat.

No manual coding required - Codepup AI handles the entire integration for you.

What Gets Integrated?

When you connect Stripe, Codepup AI automatically sets up:

A payment service connected to your Stripe account
Checkout UI components for your storefront
Success and failure result pages after payment
Webhook endpoints so your database updates when orders are placed
Edge functions to securely process payments server-side
Database migrations to store order and payment data

Two Ways to Integrate Stripe

There are two points where you can add Stripe to your project:

Method	When to Use
At project creation	You know upfront you need payments - select E-Commerce at the start
After project is created	You already have a project and want to add payments via chat

Method 1 - Set Up Stripe at Project Creation

Step 1 - Enter Your Prompt and Select E-Commerce Store

Go to the Codepup AI homepage and type your project idea in the prompt box. When the project type options appear, select E-Commerce Store (fullstack + payment + email integration).

This tells Codepup AI to build your project with Stripe payment integration and database support included from day one.

Step 2 - Enter Your API Keys

Before building starts, Codepup AI will ask you to provide your Stripe Secret Key and optionally your Resend API key for email notifications.

API keys input fields for Stripe and Resend

Fill in the fields:

Field	Where to Get It
Stripe Secret Key	Your Stripe Dashboard → Developers → API Keys
Resend API Key	Your Resend Dashboard → API Keys

Once entered, click Proceed and Codepup AI will start building your fully integrated e-commerce project.

Step 3 - Codepup AI Builds Everything Automatically

Codepup AI works through every task required to complete the payment integration one by one. You can watch the progress live in the chat.

Each task is checked off as it completes - including:

Reading edge function templates
Deploying session and webhook functions
Analyzing project structure
Creating and pushing database migrations
Creating the payment service
Building UI components and result pages
Updating routes
Uploading and building the project
Creating the webhook endpoint

All 12 payment tasks completed successfully

Once all tasks are done, you will see “All tasks completed” - your Stripe integration is live.

Method 2 - Add Stripe to an Existing Project

Already have a project built and want to add payments? You can do it anytime from the chat section.

Step 1 - Ask Codepup AI to Integrate Stripe

In the chat section of your project, type a prompt like:

"now integrate the real payment gateway using stripe"

Chat prompt asking Codepup AI to integrate Stripe payment gateway

Codepup AI will immediately check your project structure and verify if Stripe API keys are already configured.

Step 2 - Enter Your Stripe Secret Key

Codepup AI will show an Integration Keys Required prompt asking for your Stripe Secret Key.

Enter your key in the format:

sk_test_xxxxxxxxxxxxxxxxxxxxxxxxxx

Click Proceed - Codepup AI will begin modifying your project to add the full payment stack.

Step 3 - Codepup AI Modifies Your Project

Codepup AI runs through all the necessary modifications automatically - deploying functions, creating migrations, wiring up the payment service, and building checkout components.

You will see “Modification in progress…” in the chat while this runs.

Step 4 - Automated Testing

After integration is complete, Codepup AI runs automated testing on the payment flow to verify everything is working correctly end to end.

This checks that:

The checkout flow works
Stripe receives and processes payments
Webhooks fire correctly
Order data is saved to the database

Testing the Payment on Your Website

Once integration is complete, visit your published website to test the full checkout flow.

Step 1 - Go to Checkout

Browse your store and click Proceed to Checkout on a product or cart page.

Step 2 - Complete the Checkout

Depending on how Codepup AI built your project, you may see one of two checkout experiences. Both are fully connected to Stripe and work correctly.

Type A - Shipping Address + Place Order

Some projects generate a checkout page with a shipping address form and a Place Order button. The customer fills in their delivery details and confirms the order.

Fill in your shipping details and click Place Order to complete the test purchase.

Type B - Stripe Card Input Checkout

Other projects generate a checkout page with a Stripe card input form where the customer enters their credit card details directly before placing the order.

Use Stripe’s test card details to simulate a successful payment:

Test Card Number : 4242 4242 4242 4242
Expiry           : Any future date
CVC              : Any 3 digits

A successful order confirms your entire payment flow is working - from checkout to database to your Stripe dashboard.

Switching from Test to Live Payments

When you are ready to accept real payments:

Go to your Stripe Dashboard and activate your account
Copy your Live Secret Key (sk_live_...)
In Codepup AI, go to the Key section in Chat Page
Replace your test key with the Live Secret Key
