Could anybody share an example of how to use webhooks with Ignition?
Incoming, or outgoing?
If you want something else to be able to call into Ignition via HTTP, you want the WebDev module.
If you want to call some external HTTP API, you want system.net.httpClient.
In this case it's a third party application sending an http Post with a Json payload to Ignition.
I guess I should use de WebDev, do you know of any examples about this?
Take a look here -
