Let your users sign documents directly in your web or mobile app using SignatureAPI's Embedded Signing.

You need both:

* A **server** to create an envelope and get a ceremony URL.
* A **client** to display the ceremony to the recipient.

## Server side

Check [Ceremony URL](/docs/api/resources/ceremonies/ceremony-url) to learn how to get a ceremony URL using your server.

## Client side

<Warning>Don't use our API directly from the client because API keys can be exposed. If someone gets your API key, they can access all your data in SignatureAPI.</Warning>

After getting the ceremony URL, you can embed the signing interface directly into your application. You don't need any extra dependencies; just use standard components like **iframes** (for web apps), **WebView** (for Android), or **WKWebView** (for iOS).
