Granting function access to an organization - Amazon Lambda
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Granting function access to an organization

To grant permissions to an organization in Amazon Organizations, specify the organization ID as the principal-org-id. The following add-permission command grants invocation access to all users in organization o-a1b2c3d4e5f.

aws lambda add-permission \
  --function-name example \
  --statement-id PrincipalOrgIDExample \
  --action lambda:InvokeFunction \
  --principal * \
  --principal-org-id o-a1b2c3d4e5f
Note

In this command, Principal is *. This means that all users in the organization o-a1b2c3d4e5f get function invocation permissions. If you specify an Amazon Web Services account or role as the Principal, then only that principal gets function invocation permissions, but only if they are also part of the o-a1b2c3d4e5f organization.

This command creates a resource-based policy that looks like the following:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "PrincipalOrgIDExample",
            "Effect": "Allow",
            "Principal": "*",
            "Action": "lambda:InvokeFunction",
            "Resource": "arn:aws-cn:lambda:us-west-2:123456789012:function:example",
            "Condition": {
                "StringEquals": {
                    "aws:PrincipalOrgID": "o-a1b2c3d4e5f"
                }
            }
        }
    ]
}
