We have built a custom journey activity - we need to display the fields of a data extension in the UI. When the load the UI in the journey builder we request the requesttoken event and the marketing cloud journey builder in turn fires the OnrequestedToken event which gives us the Fuel2 token and the legacy token - along with the end point we can call. We have successfully used this to query a DE for a particular value (/data/v1/customobjectdata/key/relay_network_metadata/rowset) - however i cannot figure out the end point to query a data extension for its column name.
Any help would be appreciated.
