Are compat and extended new parameters?

restapi
#1

Valid request values are compat and extended, which give compatibility mode and extended mode, respectively.

I just want to be certain that this sentence means that a new parameter will be applied to ALL endpoints of the Twitter API.

#2

All endpoints that serve Tweets (GET), per the documentation.

#3

Perfect thanks for the the clarification :slight_smile:

#4

Also POST statuses/update?
