How to get techniques from a ncf api

You actually need the jsessionid cookie from your navigator (log in to Rudder and inspect your cookie), I will add authentication via rudder api token very soon

curl 'https://server.rudder/ncf/api/techniques?path=/var/rudder/configuration-repository/ncf' -k --cookie "JSESSIONID=Valueofyourcookie"

To send a technique to a server (see file api.json for exact content): 

curl -X PUT 'https://server.rudder/ncf/api/techniques' -k --cookie "JSESSIONID=cookie" -d @api.json -v -H "Content-Type: application/json"
