How it works
1
Connect your PSP
Choose your payment provider and enter your API keys. FunnelFox securely stores them and connects your account automatically.
2
Automatic product sync
FunnelFox automatically fetches your products, prices, and discounts from the PSP. They’re then available in Checkout elements.
3
Configure Checkout element
Add products to your Checkout element in the funnel Editor, and you’re ready to accept payments.
FunnelFox never stores or processes payment card details. All sensitive
payment data is handled directly by your chosen PSP.
