Fabricate can add complete Stripe payment integrations to your app. Just describe the billing model you want, and the AI generates the full implementation.
You’ll need a Stripe account and API keys. Add your keys as environment secrets after Fabricate generates the payment code. See Environment Secrets.

​
Adding Payments

"Add Stripe subscription billing with monthly and annual plans:
- Basic: $9/month
- Pro: $29/month  
- Add a billing page where users can manage their subscription"
Or for one-time payments: 
"Add a one-time payment flow — users pay $49 to unlock premium features permanently"

​

  • Stripe SDK configuration
  • Price IDs mapped to your plan names

API routes:

Subscription Patterns

​
Monthly/Annual Plans

"Add Pro ($19/mo or $190/yr) and Team ($49/mo or $490/yr) subscription tiers with annual discount"

​
Per-Seat Pricing

​
Freemium with Upgrade

"Add a premium upgrade button. Free users get 3 projects, paid users ($12/month) get unlimited"

​
Setting Up Your Stripe Keys

After Fabricate generates the payment code:
1

Get your Stripe keys

Log into your Stripe Dashboard. Go to Developers → API Keys.
2

Add keys as environment secrets

In Fabricate’s Build settings, add:
  • STRIPE_SECRET_KEY — your Stripe secret key
  • STRIPE_WEBHOOK_SECRET — your webhook signing secret
3

Set up webhooks in Stripe

In Stripe, add a webhook endpoint pointing to https://your-app.fabricate.build/api/webhooks/stripe. Listen for: checkout.session.completed, customer.subscription.updated, customer.subscription.deleted.
