# API

#### Payments via API

The API integration allows you to accept payments **using your own payment form**. Instead of using iyzico’s hosted payment page, you can collect card details on your custom-designed checkout page and process the payment directly through iyzico’s APIs.

With the API, you can implement:

* **Non-3DS** payments, where the customer completes the payment without being redirected to the bank’s authentication page,
* **3DS** payments, where the customer is redirected to the bank’s 3D Secure page for an additional authentication step.

This section provides the technical details required to connect to iyzico using **your own payment form** and to implement both Non-3DS and 3DS payment flows.
