Returns the policy of a specified bucket. If you are using an identity other than the root user of the Amazon Web Services account that owns the bucket, the calling identity must have the GetBucketPolicy permissions on the specified bucket and belong to the bucket owner's account in order to use this operation.

If you don't have GetBucketPolicy permissions, Amazon S3 returns a 403 Access Denied error. If you have the correct permissions, but you're not using an identity that belongs to the bucket owner's account, Amazon S3 returns a 405 Method Not Allowed error.


As a security precaution, the root user of the Amazon Web Services account that owns a bucket can always use this operation, even if the policy explicitly denies the root user the ability to perform this action.
