Here is where I start with that sort of thing.
The most simple REST flow.
The inject node for now is a simply manual click to fire.
You can set it for repeat in production or any sort of inject to the http node will do the get, so for example, you could get the JSON data every minute, or when a trigger / event happens, its up to you.
The http request is where the good stuff happens:
- You want to get data.
- The URL of the RESTful endpoint (can be on the Internet or an IP address of a local service).
- You generally don’t want to append the inject node timestamp or anything upstream, so ignore it.
- If you need security, things get real interesting real quick.
- Hopefully the service you are calling returns a clean JSON object, so select this option and see what you get in the debug tab.
