# iOS SDK Introduction

PayKKa provides an iOS SDK that allows you to embed the checkout directly via a WebView, facilitating the integration of the PayKKa gateway for in-app payments and status callbacks. The [Web Checkout](/payments/docs/transaction/web/hosted-web) supports various payment methods and is continuously being updated. The latest iOS SDK download link can be found in the [iOS SDK Release History](/payments/docs/developer-resources/native-sdks/ios-sdk/release-history).
