Uses the acl
subresource to set the access control list (ACL) permissions for a new or existing object in an S3 bucket. You must have WRITE_ACP
permission to set the ACL of an object. For more information, see What permissions can I grant? in the Amazon S3 User Guide .
This action is not supported by Amazon S3 on Outposts.
Depending on your application needs, you can choose to set the ACL on an object using either the request body or the headers. For example, if you have an existing application that updates a bucket ACL using the request body, you can continue to use that approach. For more information, see Access Control List (ACL) Overview in the Amazon S3 User Guide .
Warning
If your bucket uses the bucket owner enforced setting for S3 Object Ownership, ACLs are disabled and no longer affect permissions. You must use policies to grant access to your bucket and the objects in it. Requests to set ACLs or update ACLs fail and return the
AccessControlListNotSupported
error code. Requests to read ACLs are still supported. For more information, see Controlling object ownership in the Amazon S3 User Guide .
Access Permissions
You can set access permissions using one of the following methods:
Specify a canned ACL with the x-amz-acl
request header. Amazon S3 supports a set of predefined ACLs, known as canned ACLs. Each canned ACL has a predefined set of grantees and permissions. Specify the canned ACL name as the value of x-amz-ac
l. If you use this header, you cannot use other access control-specific headers in your request. For more information, see Canned ACL .
Specify access permissions explicitly with the x-amz-grant-read
, x-amz-grant-read-acp
, x-amz-grant-write-acp
, and x-amz-grant-full-control
headers. When using these headers, you specify explicit access permissions and grantees (Amazon Web Services accounts or Amazon S3 groups) who will receive the permission. If you use these ACL-specific headers, you cannot use x-amz-acl
header to set a canned ACL. These parameters map to the set of permissions that Amazon S3 supports in an ACL. For more information, see Access Control List (ACL) Overview . You specify each grantee as a type=value pair, where the type is one of the following:
id
– if the value specified is the canonical user ID of an Amazon Web Services account
uri
– if you are granting permissions to a predefined group
emailAddress
– if the value specified is the email address of an Amazon Web Services account
Note
Using email addresses to specify a grantee is only supported in the following Amazon Web Services Regions:
US East (N. Virginia)
US West (N. California)
US West (Oregon)
Asia Pacific (Singapore)
Asia Pacific (Sydney)
Asia Pacific (Tokyo)
Europe (Ireland)
South America (São Paulo)
For a list of all the Amazon S3 supported Regions and endpoints, see Regions and Endpoints in the Amazon Web Services General Reference.
For example, the following x-amz-grant-read
header grants list objects permission to the two Amazon Web Services accounts identified by their email addresses.
x-amz-grant-read: emailAddress="xyz@amazon.com", emailAddress="abc@amazon.com"
You can use either a canned ACL or specify access permissions explicitly. You cannot do both.
Grantee Values
You can specify the person (grantee) to whom you’re assigning access rights (using request elements) in the following ways:
By the person’s ID: <Grantee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="CanonicalUser"><ID><>ID<></ID><DisplayName><>GranteesEmail<></DisplayName> </Grantee>
DisplayName is optional and ignored in the request.
By URI: <Grantee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="Group"><URI><>http://acs.amazonaws.com/groups/global/AuthenticatedUsers<></URI></Grantee>
By Email address: <Grantee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="AmazonCustomerByEmail"><EmailAddress><>Grantees@email.com<></EmailAddress>lt;/Grantee>
The grantee is resolved to the CanonicalUser and, in a response to a GET Object acl request, appears as the CanonicalUser.
Note
Using email addresses to specify a grantee is only supported in the following Amazon Web Services Regions:
US East (N. Virginia)
US West (N. California)
US West (Oregon)
Asia Pacific (Singapore)
Asia Pacific (Sydney)
Asia Pacific (Tokyo)
Europe (Ireland)
South America (São Paulo)
For a list of all the Amazon S3 supported Regions and endpoints, see Regions and Endpoints in the Amazon Web Services General Reference.
Versioning
The ACL of an object is set at the object version level. By default, PUT sets the ACL of the current version of an object. To set the ACL of a different version, use the versionId
subresource.

--request-payer
(string)
Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. For information about downloading objects from Requester Pays buckets, see Downloading Objects in Requester Pays Buckets in the Amazon S3 User Guide .
Possible values:
requester
--version-id
(string)
VersionId used to reference a specific version of the object.
--expected-bucket-owner

--cli-input-json
| --cli-input-yaml
(string)
Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton
. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml
.
--generate-cli-skeleton
(string)
Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input
, prints a sample input JSON that can be used as an argument for --cli-input-json
. Similarly, if provided yaml-input
it will print a sample input YAML that can be used with --cli-input-yaml
. If provided with the value output
, it validates the command inputs and returns a sample output JSON for that command.
See ‘aws help’ for descriptions of global parameters.
The following command grants full control
to two AWS users (user1@example.com and user2@example.com) and read
permission to everyone:
aws s3api put-object-acl --bucket MyBucket --key file.txt --grant-full-control emailaddress=user1@example.com,emailaddress=user2@example.com --grant-read uri=http://acs.amazonaws.com/groups/global/AllUsers
See http://docs.aws.amazon.com/AmazonS3/latest/API/RESTBucketPUTacl.html for details on custom ACLs (the s3api ACL
commands, such as put-object-acl
, use the same shorthand argument notation).
RequestCharged -> (string)
If present, indicates that the requester was successfully charged for the request.
