You can store the credentials in a JSON file, and add the file to your Deployment Package, you will be able to import your credentials similar to reading file from your local directory.

ex: CLIENT_SECRETS_FILE = "client_secrets_web.json" SCOPES = ["https://www.googleapis.com/auth/yt-analytics-monetary.readonly"] flow = google_auth_oauthlib.flow.Flow.from_client_secrets_file( CLIENT_SECRETS_FILE, scopes=SCOPES)

Your Deployment Package (.zip) should contain your lambda function code, any-other dependencies and your JSON file

You can store the credentials encrypted in Lambda environment variables too. You can either programmatically store or configure it in the aws console.

More details:

http://docs.aws.amazon.com/lambda/latest/dg/env_variables.html

CLI:

aws lambda create-function \
    --region us-east-1
    --function-name myTestFunction
    --zip-file fileb://path/package.zip
    --role role-arn
    --environment Variables="{LD_LIBRARY_PATH=/usr/bin/test/lib64}"
    --handler index.handler
    --runtime nodejs6.10
    --profile default

Nodejs:

http://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/Lambda.html

check on

Variables: {

in the below code.

To Encrypt, check on KMSKeyArn and provide your KMS Arn Value.

var params = {
  FunctionName: 'STRING_VALUE', /* required */
  DeadLetterConfig: {
    TargetArn: 'STRING_VALUE'
  },
  Description: 'STRING_VALUE',
  Environment: {
    Variables: {
      '<EnvironmentVariableName>': 'STRING_VALUE',
      /* '<EnvironmentVariableName>': ... */
    }
  },
  Handler: 'STRING_VALUE',
  KMSKeyArn: 'STRING_VALUE',
  MemorySize: 0,
  Role: 'STRING_VALUE',
  Runtime: nodejs | nodejs4.3 | nodejs6.10 | java8 | python2.7 | python3.6 | dotnetcore1.0 | nodejs4.3-edge,
  Timeout: 0,
  TracingConfig: {
    Mode: Active | PassThrough
  },
  VpcConfig: {
    SecurityGroupIds: [
      'STRING_VALUE',
      /* more items */
    ],
    SubnetIds: [
      'STRING_VALUE',
      /* more items */
    ]
  }
};
lambda.updateFunctionConfiguration(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Hope it helps.
