Plaid’s Auth product exclusively supports checking or savings accounts. Other types of depository accounts, such as money market accounts, are not supported because they do not consistently provide account and routing numbers. Users will be unable to select this type of account when Auth is passed in the products array of your
link_token configuration when initializing Link.
If you need to get data for a money market account or other type not supported by Auth, you can still use other products such as Transactions to access your account information, however you will need to ensure that Auth is not included in the products array for these account types to be available to users.
If you believe an account type is being mis-categorized as a money market account by a Plaid integration and should be checking or savings, please let us know by creating a support ticket.
