I have a maybe a bit stupid beginner question.
I´m using Ahrefs in Seotoolsforexcel and it works fantastic.
On the ahrefs website I see that the Api is only available for enterprise clients (not my case).
How am I using the Api ?
SeoTools for Excel has access as an enterprise client and offers our own Ahrefs app to authenticate with and gain access to the API to our users 
Ahh ok. Nice. Is this the case for other connectors as well ?
Typically those connectors with the Login button. Others require different type of authentication such as API key or none at all
Thanks ! Not sure if I understand this... Connectors like Builtwith are available without own Api key?
