I have aadhaar card dataset. I need to find the top 3 states where the percentage of Aadhaar cards being generated for males is the highest. The dataset contains the data:

I have to create custom authorization using AWS API Gateway and Lambda.

I followed all the step mention on offical doc. But at the end gateway is giving Unauthorized

Below are the steps I followed.

1) Created lambda function (according to the blueprint available on github). It will return policyDocument in the proper format. This has been tested with following test data - { "type": "TOKEN", "methodArn": "arn:aws:execute-api:us-west-2:xxxxxxxxxx:fgdfgdfg/null/GET/", "authorizationToken": "Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpZCI6IjEyMzQ1Njc4OTAiLCJuYW1lIjoiSm9obiBEb2UiLCJhZG1pbiI6dHJ1ZX0.x8R6LPytDMrPuUBY71skyLBUrkme86DhioN3L7LY_-0" }

2) Create an API. Choose 'Create Method' -> Get -> Selet Integration type as 'Lambda Function' -> Choose region and lambda function name that has been created in the previous step.

• Refer this.
• Integration request
• Integration response

3) Click on Authorizers (on left panel) -> Create New Authorizer -> Given Authorizer Name -> Choose Lambda as a type -> Choose Lambda function -> Lambda execution role is the arn with basix execution role policy -> payload as Token -> Token Source is 'method.request.header.Authorization' -> caching is disable.

Refer this

4) Test the Authorizer and it returns proper policy

5) I have deployed the API

6) Trying to invoke URL with Postman with 'Authorization: Bearer '. And output is { "message": "Unauthorized" }

Any help will be appreciated! Thanks.
