A simple CLI to test API Gateway endpoints with IAM authorization. Uses the AWS SDK, AWS Cognito JS SDK, and the generic API Gateway Client. Using the login information given, this tool logs a user into the Cognito User Pool, gets the temporary IAM credentials, and makes the API request. It can be difficult to do these steps by hand without scripting them.

To install globally run the following:

$ npm install -g aws-api-gateway-cli-test

$ apig-test \
  --username='johndoe' \
  --password='password' \
  --user-pool-id='us-east-1_Xxxxxxxx' \
  --app-client-id='29xxyyxxyxxxyyxxxyy' \
  --cognito-region='us-east-1' \
  --identity-pool-id='us-east-1:99xxyyx-9999-9999-xx0x-99xxxxxxxx' \
  --invoke-url='https://99xxxxxxx.execute-api.us-east-1.amazonaws.com' \
  --api-gateway-region='us-east-1' \
  --api-key='x3xaacea33DCDA3aqafae28aCdaeEWXX1ada3acx' \
  --path-template='/users' \
  --method='GET' \
  --params='{}' \
  --additional-params='{}' \
  --access-token-header='cognito-access-token' \
  --body='{}'

• username The username of the Cognito User Pool user.

• password The password of the Cognito User Pool user.

• user-pool-id The Cognito User Pool Id.

• app-client-id The Cognito User Pool App Client Id.

• cognito-region The Cognito User Pool region. Defaults to us-east-1.

• identity-pool-id The Cognito Identity Pool Id.

• invoke-url The API Gateway root endpoint.

• api-gateway-region The API Gateway region. Defaults to us-east-1.

• api-key The API key if required by the method. Defaults to none.

• path-template The path template of the API.

• method The API method. Defaults to GET.

• params The API params (path, header, querystring, etc) as a JSON string. Defaults to '{}'.
