To provide authorized access for your user, your application should obtain a user token (the Link token) from the /users endpoint. This is a single use, short-lived token which is used to initialize our Wink Widget.

Time of expiry is included when a token is generated. You may also listen for events from the SDK when the token has expired (see below).

Your server or application should generate a new Link token for the user each time you wish to launch the widget.

Refreshing a User's Token

You can refresh a user's token by calling the /tokens endpoint. Simply pass the userId of the user as a parameter in the query to give the user a new token.

The Token object

Event Listeners

The SDK also emits events that can be caught by your native application to allow the application to react and perform functions as needed.
