REST API v1.1 rate Limit


Hi and Thank you in advance,

As i notice the new rate limit for the REST APIv1.1 get search is now 180 per 15 min, but i tried to find somewhere it would specify it and i can’t.

Like the REST API v1.0 was 150 API call per hours and if authenticated it was 300 per users.
I would like to know if the 180 API calls per 15 minute is per user or per applications?

Thank you in advance.
