# Installation ### From NPM Tebex.js is available as an NPM package, which you can install using your preferred JS package manager: ```bash npm install @tebexio/tebex.js ``` The **`Tebex`** object can then be imported into your code like so: ```javascript import Tebex from "@tebexio/tebex.js"; ``` ### From Our CDN Alternatively, we also provide Tebex.js via our own CDN, which you can add as a script within the `` tag of your website: ```html ``` {% hint style="info" %} We will automatically update `v/1.js` with new minor and patch releases of Tebex.js. This shouldn't present any breaking changes, but if you would prefer to stay on a fixed version, you can specify the full version number in the URL, for example `https://js.tebex.io/v/1.1.1.js`. Our version history can be found on our [GitHub](https://github.com/tebexio/Tebex.js/releases) releases page. {% endhint %} When installing Tebex.js this way, the **`Tebex`** object will become available globally on the `window` object. We recommend using `defer` on the script to prevent it from blocking your website's initial page render, but when doing do, it's important to **wait for the page `load` event** before you begin configuring the checkout or payment portal: ```html ``` ### Next Steps The **`Tebex`** object provides the following APIs: * [`Tebex.checkout`](https://docs.tebex.io/developers/tebex.js/checkout) - for allowing customers to make purchases without leaving your website. * [`Tebex.portal`](https://docs.tebex.io/developers/tebex.js/payment-portal) - for allowing existing customers to review their purchase history and subscriptions without leaving your website.
