This parameter is applicable for OData service only. The approach will work if you are using OData data source or some of the SQL database data sources - for plain REST you will need to implement your own filtering.
ok that make sense, is there any example around of a good way on how to implement a filter?
Would creating a custom method in the non-generated .TS file, where I pass the Result object of the API call, and the Filter value, do the filtering inside the method, and return the filtered Result object, be a good approach?
Thank you for the support
