Mapping APIs of different applications with different authentication

Hi, I am a beginner for KONG API Gateway. I am trying to map APIs of different applications, who already have their own authentication type.
Ex: Application A uses Basic Authentication, B uses Token based Authentication
So, my question is how exactly can we map these type of APIs where the credentials provided at Gateway level can also be accessed by the upstream API. Also, is there a way where in we can use only one type of authentication for multiple application’s APIs with different authentications?
Any suggestion would be appreciated. Thank you!
