Card Payments via InSite
An embedded payment form that keeps customers in your store.
What is InSite?
InSite is Redsys's embedded payment form technology (v3). It places a card input directly in your checkout page — similar to Stripe or PayPal — so customers complete payment without ever leaving your store. Despite being embedded in your page, the form is actually a secure Redsys iframe, so card data never touches your server.
How does it work?
- Customer reaches checkout and sees card fields integrated in your page.
- Customer enters card number, expiry date, and CVV in the embedded form.
- Payment processes in the background via Redsys.
- 3D Secure authentication if required (popup or redirect).
- Order confirms on the same page — no redirect.
