The best way you can get Authorize through a financial institution with Flinks is with the LoginId. You can find more details about that here.

Iif you don't want to do a live scraping you need to use the parameter MostRecentCached:true to get the latest information we saved. By using this parameter, the API will answer you faster because it simply gives you back the information already saved in our data base.

Let's see an example with the LoginId.

Call Authorize endpoint with the parameter MostRecentCached:true 

You will need the RequestId returned by the Authorize call.

Call any other endpoint to get the data using the RequestId from the Authorize:

(In this example we are going to call the GetAccountsDetail endpoint, but you can also use the same RequestId to call the other aggregation endpoints)
