How to Integrate Stripe Payments Into Your App in Minutes (No Code!)
Ever wondered how to start making money from the apps you build? One of the most common questions for new developers and creators is how to integrate a payment system like Stripe. While this can often be a complex and frustrating process, especially for those without a deep coding background, there’s now a much simpler way. This guide will walk you through integrating Stripe into your application using Lovable AI, a platform that turns your ideas into full-stack apps, without you needing to write a single line of code.
The Challenge of Payment Integration
[0:11.000]
Traditionally, integrating payment gateways involves navigating complex APIs, setting up backend servers, and handling secure transactions. Tools exist to generate code, but they can still leave you with a process that is “incredibly frustrating and borderline impossible” if you’re not a seasoned developer. The goal is to accept payments, not become a backend expert overnight.
A Better Solution: Lovable AI

Instead of wrestling with code, we can use an AI-powered tool that simplifies the entire workflow. If you’ve seen how Lovable AI can seamlessly set up a backend with its native Supabase integration, you’ve only scratched the surface. We’re about to apply that same level of simplicity to payment processing.

This tutorial will show you how to get a fully functional Stripe integration up and running in your application, allowing you to start monetizing your work immediately. The best part?
You don’t need any coding experience at all. You can follow along step-by-step and achieve this simply with Lovable AI.
Let’s dive in and start building.
Step 1: Create a Basic Application
[0:42.066]
To demonstrate the Stripe integration, we’ll start by building a very basic application. The complexity of the app doesn’t matter for this process, so we’ll keep it simple. We’ll head over to Lovable.dev and prompt the AI to create a simple app.
[0:56.566]
We’ll use a straightforward prompt to get started.
Create a note taking app
[1:06.866]
In seconds, Lovable AI generates a functional note-taking application. While we could spend time refining the user interface, our focus is on the backend functionality. With this base app, we’re ready to add the necessary features for monetization: user accounts and a payment gateway.
Step 2: Set Up User Authentication with Supabase
Before we can charge users, we need a way for them to sign up and log in. This requires a user authentication system and a database to store user information. Lovable makes this incredibly easy by integrating with Supabase.
[1:34.400]
First, we need to connect our app to a Supabase project, which will act as our database and authentication server. We can do this directly from the Lovable interface.
[2:00.400]
In the Lovable editor, you’ll find an option to connect to Supabase. You can either create a new project on Supabase or connect to an existing one. Once connected, Lovable can start building out the authentication features.
[2:31.966]
With Supabase connected, we can ask Lovable to implement the user login feature. A simple prompt is all it takes:
Lets now add user authentication in order to access the app
[3:02.366]
Lovable’s AI will then automatically generate a login and sign-up page for the app, which it calls “Note Nook.” Now, users must create an account and log in before they can access the note-taking functionality. We’ve successfully gated our content, which is the first step toward creating a subscription-based service.
Step 3: Integrate Stripe for Subscriptions
Now for the most important part: adding the payment system. We want users to subscribe via Stripe before they can access the app’s features.
[3:24.466]
We’ll prompt Lovable AI to set up the Stripe integration.
Setup stripe integration
[3:45.866]
Lovable will present a checklist of requirements. Since we’ve already connected Supabase and set up authentication, those items are checked. The remaining steps involve configuring Stripe. We need to:
- Set up a Stripe account and a product.
- Provide our Stripe secret key to Supabase Edge Functions.
[4:08.066]
Lovable provides a secure input form to handle your sensitive API keys.
Important Security Note: Never paste your secret API keys directly into the main chat prompt. Only use the dedicated, secure input fields that Lovable provides for this purpose.
[4:19.466]
You’ll get your Stripe Secret Key from your Stripe dashboard under the Developers > API keys section. Copy this key and paste it into the secure form within Lovable.
[4:53.600]
Next, you need to provide the Price ID for the subscription product you created in Stripe. This tells Lovable which product the user is subscribing to. You can find this ID on your product’s page in the Stripe dashboard.
[5:11.233]
Copy the Price ID from Stripe and provide it to Lovable in the chat prompt. For example:
I added the stripe API key, here is the price id: price_1QBw99...
[5:35.333]
Once you provide the key and ID, Lovable’s AI gets to work. It creates the necessary Edge Functions in Supabase, updates the user interface to handle subscriptions, and implements the entire checkout flow automatically.
Testing the Final Product
With the integration complete, Lovable creates a paywall. To test this, it’s best to publish the app and open it in a new browser tab, as the full Stripe redirect functionality works best on a live site rather than in the preview window.
[5:59.266]
After signing up for a new account on the live app, the user is now greeted with a “Subscribe to Access Notes” page. Clicking “Subscribe Now” redirects them to a secure Stripe checkout page.
[6:45.866]
Using Stripe’s test card numbers, you can complete the checkout process without using a real credit card. After a successful “payment,” the user is redirected back to the app. When they log in again, they bypass the subscription page and gain full access to the note-taking functionality.
[7:21.900]
And just like that, you have a fully monetized application! Users must now sign up and pay via Stripe to use your service. Lovable AI handled all the complex backend code, database setup, and frontend changes, turning a potentially week-long coding project into a task of a few simple prompts. Now you can focus on making your app even better for your paying customers.
