Server-Sent Events|A server-sent event is when a web page automatically gets updates from a server.
Yes They are similar
The difference is:
1) using SSE you pull updates to your Front-End.
2) using Web-hook you pull updates to your Back-End.
The first is simplier, easier to implement and manage. The second is more secure/reliable.
Also, some server may implement long-polling, which will delay response until new data arrives, so it might be used instead of SSE.
If you have a specific example, I will definitely create it
For example, I want Construct 3 to read the GPS coordinates at that moment and they can be displayed as variables from the outside. That calling a URL returns those values.
