API problems with same domain different keys

[TKITS_5190]

Hi Community,
I guess I have a very basic question.
In Power Query I use two API keys that point to the same domain but have different accesskeys/usernames and secretkeys/passwords. I am not able to distinguish the queries in the data source settings because the domain is the same. So I can only use one API and not both APIs. I tried to place the API key and password in front of the domain. This works in the browser but not in power query e.g. https://accesskey:secretkey@api.domain.com
Is there an easy workaround to distinguish the two APIs?
Thanks in advance
