I just watched a bunch of tutorials for PushCrew which no longer exists. Now I'm trying to put in a campaign and have no clue how to get the API I need. I know I need a javascript code and I have looked through plugins and nothing addresses that. They are only for Rest API and I have no idea what that is.
