# Initialize JWT Token

## Initialize a new Authentication Token

<mark style="color:green;">`POST`</mark> `/api/token`

This endpoint creates a temporary JWT token to authenticate the Taiki client CDK. It expires in 1 hour for security reasons.&#x20;

Your application should store the `taiki_user_id` for each unique client on your end. In future years, when you Initialize the JWT token, provide the `taiki_user_id`  and Taiki will retrieve the prior year used platforms and documents connected to the `taiki_user_id`.

## Modes

The JWT token will incorporate which of the two [Modes/Base Urls](/docs/detailed-references/modes-base-urls.md) you are using. Just [Invoke the Taiki App](/docs/detailed-references/invoke-the-taiki-app.md) with the JWT token and the app will automatically use that mode.
