REST API documentation

I’m looking for some basic documentation on the REST API module in FreePBX. Simple things like clicking a button and dialing out. I can’t seem to find documentation on this module. Can anyone point me in the right direction?

There unfortunately is no documentation on it and what you want to do doesn’t not exist in it

Is this more of an Asterisk feature?

Thanks I will take a look at that. Some PHP examples would be greatly appreciated.

If you read the article it talks about PHP libraries.
