# API Integration

API integration is the most flexible and common way to connect your platform to Zru. Before you start you will need your **API keys** (public and secret), which you can get from **Settings** ▶︎ **Integration**.

> 🧐 If your website is built on a CMS (WooCommerce, Shopify, PrestaShop...), you may find it easier to use a plugin. See the [plugin integration guide](https://academy.zrupay.com/es/article/integracion-con-plugins-1l9mpvr/).
