If you are not creating the endpoints using the UUI way described in the above reference 
, then you can call AAI's RESTFUL API using postman or a curl command to create these endpoints (i.e. networkroute) and the payloads for each of these 6 REST requests as well as the URLs can be found in the postman collection that is attached to this wiki page. Included in this postman collection is the URL and the payload required to create 3 logical links that are representing these 6 endpoints, however, you do not need to create these logical-links manually because SO creates them for you. You only need to do it manually if you are not testing with SO and instead, you are calling SDNC directly (no SO involved). Please see the postman collection for details.
