Hosted checkout
The simplest integration — share a checkout URL. No API key required.
Checkout link
Replace productId with your product UUID from the dashboard:
Checkout URL
https://flintpay.cc/checkout/productId?success_url=https://yoursite.com/thank-you&cancel_url=https://yoursite.com/cancelled&[email protected]Query parameters
success_url— thank-you page after payment (optional)cancel_url— page if buyer cancels (optional)email— prefill buyer email (optional)
Use success_url for UX only. Do not fulfill orders from the redirect — use order.completed webhooks.
