# IAM identity-based policies for directory buckets
Identity-based policies

Before you can create directory buckets, you must grant the necessary permissions to your AWS Identity and Access Management (IAM) role or users. This example policy allows access to the `CreateSession` API operation (for use with Zonal endpoint [object level] API operations) and all of the Regional endpoint (bucket-level) API operations. This policy allows the `CreateSession` API operation for use with all directory buckets, but the Regional endpoint API operations are allowed only for use with the specified directory bucket. To use this example policy, replace the `user input placeholders` with your own information.
