Does hapikey is same as Token oauth?

[#1]

I'm trying to update contacts with API, does hapikey is same as token or oauth?
if so , then every updates I need to ask for user to grant access?

Thank you in advance

I found solution here :

API key difference between hapikey and access token OAuth

Hi, I am referring to this link: https://developers.hubspot.com/docs/methods/oauth2/using-access-tokens Just want to know what is the difference between hapikey and access_token? in terms of permission and usage limits?
