Incoming or outgoing REST?
I going is kind of easy and straightforward for calling simple services.
But you gotta make sure you add a record into that rest table you create.
Since it’s only gonna ever have just one record in it, I just manually edit it in the backend database tool.
It will always be there and never get deleted so that’s all that’s really required.
Incoming is more tricky to set up because you have to have a matching table and process to go along with the service.
