Sell Subscriptions & Products
Payment Providers
Connect your payment provider to start accepting payments through Zellify.
Zellify never touches your money. All transactions flow directly to your connected Stripe or Paddle account. We simply render checkout forms on your behalf.
Available Providers
Navigate to Settings → Payments to connect:
Stripe
Accept real payments via Stripe
Stripe Sandbox
Test payments without charging real cards
Paddle
Accept real payments via Paddle (MoR)
Paddle Sandbox
Test Paddle billing and subscription flows
Most users connect either Stripe or Paddle — though you can use all four simultaneously if needed.
Connecting Stripe
Click Connect next to Stripe or Stripe Sandbox. You'll be redirected to Stripe OAuth to authorize access, then returned automatically.
Connecting Paddle
Log into your Paddle dashboard:
Live: vendors.paddle.com
Sandbox: sandbox-vendors.paddle.com
Go to Authentication and create a new API key with full permissions and no expiration
Copy the key and paste it into the Paddle API Key field in Settings → Payments
Click Connect
How Checkouts Work
Once connected, create products at Products and select your payment provider.
Stripe: We use the Checkout Sessions API. When a customer initiates checkout, we create a Stripe Customer and Checkout Session, then render the payment form (card, express checkout, etc).
Paddle: We create a Paddle Customer and Transaction, then render the Paddle checkout form.
Customers are created before payment completes. This enables proper attribution and analytics tracking.
Webhooks & Entitlements
Zellify registers webhooks with your payment provider only for attribution and analytics (viewable at Dashboard). We never perform manual charges or interfere with transactions.
To grant entitlements to your users (e.g., unlock "Gold" subscription after purchase), you must:
Register your own webhook endpoints in Stripe or Paddle
Listen for payment events per the provider's documentation
Update user entitlements in your database accordingly
This ensures users get proper access when they sign into your app.
