Sets the list of accounts selected by the customer. This replaces any previously stored list.

To find the account IDs, use the account_id of each account returned by Retrieve Accounts V3.

You must set the list before you can retrieve it, and it must include at least one account ID. Calling Retrieve Selected Accounts User’s Preferences before the list has been set returns a 404.

In order for a widget to use these preferences, append the enable_user_preferences_sync parameter to the widget URL, for example https://widgets.thisisbud.com/<widget_path>?token=<token>&enable_user_preferences_sync. You can choose which widgets sync by adding the parameter to each widget URL individually.
