LogicMonitor version 118 announced the ability to import/ export custom HTTP integrations!
So, I've taken some of our available documentation and made a best effort to provide importable files that reduce the effort required to get up and running.
These are only a starting point; APIs change and update all the time, you may want to add/change/tweak these, so treat them like building blocks and don't hesitate to reach out to LogicMonitor support!
