Make sure Tile38 is properly installed on Server 1 and Server 2.

Start an instance of Tile38 on Server 1.

$ tile38-server

Start a wehbook test consumer on Server 2.

$ tile38-server --webhook-http-consumer-port 8080

Create a webhook on Server 1 that points to an endpoint on Server 2.

tile38> SETHOOK myhook http://server-2-ip:8080/endpoint NEARBY fleet FENCE POINT 33 -115 50000

Now you can send Server 1 data ...

tile38> SET fleet truck1 POINT 33 -115
tile38> SET fleet truck1 POINT 33 -116

... and see the geofence notifications being delivered to Server 2.
