gistfile1.txt

# First we update the authorizer to call the right lambda function including the qualifier :xxx at the end of the function ARN
aws apigateway update-authorizer --rest-api-id XXXXXXXXX --authorizer-id XXXXX --patch-operations op=replace,path=/authorizerUri,value=arn:aws:apigateway:us-west-2:lambda:path/2015-03-31/functions/arn:aws:lambda:us-west-2:XXXXXXXXXXX:function:Authorize2:AliasOrVersion/invocations

# Then we give API Gateway permission to invoke the authorizer using resource policies on the Lambda function
aws lambda add-permission --function-name Authorize2 --statement-id mystatement12334 --action lambda:InvokeFunction --principal apigateway.amazonaws.com --qualifier AliasOrVersion --source-arn arn:aws:execute-api:us-west-2:XXXXXXXXXXX:XXApiIdXX/authorizers/XXAuthorizerIdXX

# You can check the structure of your authorizer with
aws apigateway get-authorizer --rest-api-id XXXXXX --authorizer-id XXXX

# You can also check the policy against the lambda function with
aws lambda get-policy --function-name Authorize2 --qualifier AliasOrVersiuon
