Sequence Diagram for Creating Linked Account and Session Token Linked Accounts refers to the end-users or customers of our users who utilize the integrations built using the Cobalt platform. When you create a Linked Account, you must provide a linked_account_id. This ID can be anything you want, but it must be unique. Most of the time, the linked_account_id is an ID from your internal data model that represents a user or account in your system. For example, if you have a user in your system with the ID account:12345, you could use that ID as the linked_account_id for your Cobalt Linked Account. Auth tokens and User configurations will be stored against the Linked account id of each user.
To learn more about Linked Accounts, you can refer to the Linked Accounts Guide here.
