I am trying to get siteAccountId and siteId from yodlee fastlink. I am following below process and no idea how I can get/read siteAccountId and siteId from yodlee end.
Thanks
You can call getAllSiteAccounts API and from the response of this API you can get the siteAccountID based on the "DisplayName" and the value from "created" which will tell you when it was created incase you have same site added twice.
So for the DAGBank which you linked , after calling the above API search for DAGBank and get the SiteAccountID and incase you have two DAGBanks added check the "created" field as well.
