# Web SDK

Youverify offers SDKs for web and mobile platforms, enabling you to integrate our identity verification solutions into your applications. With our SDKs, you can perform liveness checks, ID document capture, and custom workflow builder (CWB) with ease and security.

Our web SDK is compatible with all major browsers and devices, and our Android SDK supports API level 24 and above. We are also working on an iOS SDK that will be available soon. To get started with our SDKs, please visit our documentation page or contact us for more information.

To install the SDKs, kindly follow the links below:

Alternatively, if you are trying to integrate the SDK into a project that is NOT based on Node.js, you can use the CDNs below:

Our NPM packages are served directly via public CDNs like jsDelivr and UNPKG, following a defined URL structure.

URL Structures&#x20;

jsDelivr<br>

```
https://cdn.jsdelivr.net/npm/<package-name>/<file-path>
```

* `<package-name>`: The name of the package on NPM.
* `<file-path>`: The relative path to the file inside the published package.

UNPKG<br>

```
https://unpkg.com/:package@:version/:file
```

* `:package` → Name of the NPM package
* `:version` → (Optional) Specific version to load
* `:file` → Path to the file within the package

Example (Youverify Passive Liveness)

Our package is: `youverify-passive-liveness-web`And your desired file is: `dist/index.js`

jsDelivr:<br>

```
<script src="
https://cdn.jsdelivr.net/npm/youverify-passive-liveness-web/dist/index.js"></script>
```

UNPKG:<br>

```
<script src="
https://unpkg.com/youverify-passive-liveness-web/dist/index.js"></script>
```

Or with a version:

```
<script src="
https://unpkg.com/youverify-passive-liveness-web@0.0.9/dist/index.js"></script>
```
