Use of higher rate limits for API calls

An update on how to connect to exact online premium would be much appreciated. Our company moved yesterday from Professional to Exact Online Premium.

how can we tell Invantive to use higher rate limits in case of Premium subscription ?

The rate limits will be provided through the Exact Online APIs. No user action is required.

Please note that current versions of Exact Online Premium no more offer the 300 API calls per minute limit. It is all 60 again.
