Granting function access to an organization

To grant permissions to an organization in AWS 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

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:lambda:us-east-2:123456789012:function:example",
            "Condition": {
                "StringEquals": {
                    "aws:PrincipalOrgID": "o-a1b2c3d4e5f"
                }
            }
        }
    ]
}
