targetId

The unique identifier (ID) of the root, OU, or account that you want to attach the policy to. You can get the ID by calling the ListRoots, ListOrganizationalUnitsForParent, or ListAccounts operations.

The regex pattern for a target ID string requires one of the following:

• Root - A string that begins with "r-" followed by from 4 to 32 lowercase letters or digits.

• Account - A string that consists of exactly 12 digits.

• Organizational unit (OU) - A string that begins with "ou-" followed by from 4 to 32 lowercase letters or digits (the ID of the root that the OU is in). This string is followed by a second "-" dash and from 8 to 32 additional lowercase letters or digits.
