## Working with grants

* **Note**\
  The `GranteePrincipal` field in the `ListGrants` response usually contains the grantee principal of the grant. However, when the grantee principal in the grant is an AWS service, the `GranteePrincipal` field contains the [service principal](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_principal.html#principal-services), which might represent several different grantee principals.
