Any Tips On HTTP Service?

I am quite new to scripting, i can only do post requests. If anyone has time can anyone explain how HTTP service works?

HTTPService is mainly used for accessing webhooks and other third party structures.

Though, there are some other cool features like:
:JSONEncode and its counterpart :JSONDecode

:JSONEncode converts a dictionary into a string.
:JSONDecode converts this generated string into the dictionary.

:GenerateGUID is useful for creating ids for instances as it provides unique ids that are usually very lengthy.
