Customer comment for API - Authentication page

[nastovg]

There was complain by a customer while chatting from (SZDM) about the Authentication page, for the API usage.I don't think it's major issue only that it's useful to for you to know and decide if you would like to change something or not.

Issue Description

Here is the quote, while they were setting up Postman to call API in the EU region:
Note, the API documentation contains conflicting info:

If you are on the Datadog EU site, set the environment variable DATADOG_HOST to https://api.datadoghq.eu/ or override this value directly when creating your client.
-> In Postman the global collection-level variable to override was simply "site".
