(HELP) Manually update AHREFS API?

How can I update ahrefs API manually, where it gets saved?

I am asking this because I was using netpeak/urlprofiler and there I was manually updating APIs, as I only have access to API, I am not given AHREFS login.

Thank you.

Not sure what you mean with this. Are you talking about the Ahrefs connector? If so, then it's possible to update using the Manager:
