Layer

Any Plaid experience a user sees such as connecting a bank account, verifying identity, or sharing a credit report is considered a session. Today, most sessions happen through Link and the token to start these Link session is a link token created and configured via link/token/create. Sessions are a higher level abstraction where configuration primarily happens in Plaid Dashboard. Depending on the template id provided, the session may a Link session, specified by a Link token, or may be another experience in the future. A primary benefit is that configuration changes can be done in Dashboard with no code changes required.
Currently, this endpoint is only supported for Layer templates and Link but is reserved in the future to initialize other end-user Plaid experiences. The returned Link token is used as an parameter when initializing the Link SDK. For more details, see the Link flow overview.
