Auth + express.js + aws api gateway?

Question

Amazon Web Services

Hey! :)
* There is a backend on express.js. The backend has multiple endpoints (APIs)
* Architecture: AWS Cognito + AWS Lambda + AWS API Gateway

One of the endpoints should be admin only.

How to make such authorization?
a) API Gateway Lambda Authorizers
b) passport.js to our backend
c) AWS Signature
d) any ideas you have

Thanks :)

Answer 1

There are only a few authorization methods through API Gateway:

• API Gateway Lambda Authorizers
  
• API Gateway Cognito Authorizers
  
• API Gateway API KEYS
  
• IAM policy
  
• Any self-written solutions on the back
  

There are no others in nature.
