I am trying to call a Lambda Function through AWS API Gateway. When I mention Authentication type NONE it works fine but API become public and anyone with url can access my API. To make API call secure, I am using Authentication type AWS_IAM and also attached AmazonAPIGatewayInvokeFullAccess policy to my user but getting this error:

{ message: "Missing Authentication Token"}

I don't know what I am missing here.

API + RESOURCE URL https://1111.execute-api.us-east-1.amazonaws.com/dev/get-list

The /get-list was missing

And of course, you need to check that the method configuration looks like this:
