NationBuilder have released an official Paths API, however, the API is in it’s infancy and does not yet allow us to fully add Paths to FieldEdge. We will continue to work with NationBuilder to add further functionality to the API.
Update Nov 30, 2016
We have suggested to NationBuilder that they enhance the Paths API and we are trying to gather community support for it.
