You can use the [system.net](http://system.net) scripting functions to hit external APIs.

Another option would be to use the webdev module and have the other systems request the data.

Use WebDev, not [system.net](http://system.net).

For example see our RWS (Restful Web Services) module that allows reading/writing tags from an external application into Ignition. This is used inside our another module ARSCADA but is also available as a separate module as well. This is based on WebDev module for corresponding version of Ignition.
