I noticed in developer tools there is a datatable call under Architect but when test got a 501 not implemented message (/api/v2/flows/datatables). Is there any timetable when this will be implemented? I am assuming that architect would be able to use these to lookup values internally?
I tried searching but could not find any information on them.
In the mean time, you can use the Data actions api to lookup data from external contacts - not perfect as someone could change the data but it is a functional workaround. Once the custom fields for external contacts comes into play I see ALOT of potential.
