You can use this operation to determine if a bucket exists and if you have permission to access it. The action returns a 200 OK if the bucket exists and you have permission to access it.
See https://www.paws-r-sdk.com/docs/s3_head_bucket/ for full documentation.
s3_head_bucket(Bucket, ExpectedBucketOwner = NULL)[required] The bucket name.
Directory buckets - When you use this operation with a directory
bucket, you must use virtual-hosted-style requests in the format
Bucket_name.s3express-az_id.region.amazonaws.com. Path-style requests
are not supported. Directory bucket names must be unique in the chosen
Availability Zone. Bucket names must follow the format
bucket_base_name--az-id--x-s3 (for example,
DOC-EXAMPLE-BUCKET--usw2-az1--x-s3). For information about bucket
naming restrictions, see Directory bucket naming rules
in the Amazon S3 User Guide.
Access points - When you use this action with an access point, you must provide the alias of the access point in place of the bucket name or specify the access point ARN. When using the access point ARN, you must direct requests to the access point hostname. The access point hostname takes the form AccessPointName-AccountId.s3-accesspoint.Region.amazonaws.com. When using this action with an access point through the Amazon Web Services SDKs, you provide the access point ARN in place of the bucket name. For more information about access point ARNs, see Using access points in the Amazon S3 User Guide.
Object Lambda access points - When you use this API operation with
an Object Lambda access point, provide the alias of the Object Lambda
access point in place of the bucket name. If the Object Lambda access
point alias in a request is not valid, the error code
InvalidAccessPointAliasError is returned. For more information about
InvalidAccessPointAliasError, see List of Error Codes.
Access points and Object Lambda access points are not supported by directory buckets.
S3 on Outposts - When you use this action with Amazon S3 on
Outposts, you must direct requests to the S3 on Outposts hostname. The
S3 on Outposts hostname takes the form
AccessPointName-AccountId.outpostID.s3-outposts.Region.amazonaws.com.
When you use this action with S3 on Outposts through the Amazon Web
Services SDKs, you provide the Outposts access point ARN in place of the
bucket name. For more information about S3 on Outposts ARNs, see What is S3 on Outposts?
in the Amazon S3 User Guide.
The account ID of the expected bucket owner. If the account ID that you
provide does not match the actual owner of the bucket, the request fails
with the HTTP status code 403 Forbidden (access denied).
