# xApp Tokens

> Learn how xApp Tokens provide the xApp session URL and PIN code used to access and authenticate xApp sessions via Cognigy flow input objects.

URLs as well as the PIN code to access an xApp session are exposed via Cognigy Tokens.

## xApp PIN Page URL

The xApp PIN Page URL token provides a URL to access the PIN Page.
You can get this URL when the [xApp: Init Session](/ai/agents/develop/node-reference/xApp/init-xApp-session#with-pin) Node is executed.
This URL is also accessible via `input.apps.baseUrl` in the input object.

## xApp Session PIN

The xApp Session PIN token provides the PIN code to access the xApp Session.
This PIN is also accessible via `input.apps.session.pin` in the input object.

The PIN code is only valid for 5 minutes after it is created by the [xApp: Get Session PIN](/ai/agents/develop/node-reference/xApp/get-xApp-session-PIN) Node.

## xApp Session URL

The xApp Session URL token provides the URL to access the xApp Session without a PIN.
You can get this token
when the [xApp: Init Session](/ai/agents/develop/node-reference/xApp/init-xApp-session#without-pin) Node is executed.
This URL is also accessible via `input.apps.url` in the input object.
