Uploads a part in a multipart upload.
You must initiate a multipart upload (see CreateMultipartUpload ) before you can upload any part. In response to your initiate request, Amazon S3 returns an upload ID, a unique identifier that you must include in your upload part request.
Part numbers can be any number from 1 to 10,000, inclusive. A part number uniquely identifies a part and also defines its position within the object being created. If you upload a new part using the same part number that was used with a previous part, the previously uploaded part is overwritten.
For information about maximum and minimum part sizes and other multipart upload specifications, see Multipart upload limits in the Amazon S3 User Guide .
For more information on multipart uploads, go to Multipart Upload Overview in the Amazon S3 User Guide .
Directory buckets - For directory buckets, you must make requests for this API operation to the Zonal endpoint. These endpoints support virtual-hosted-style requests in the format ``https://bucket_name .s3express-az_id .*region* .amazonaws.com/key-name `` . Path-style requests are not supported. For more information, see Regional and Zonal endpoints in the Amazon S3 User Guide .
Permissions
General purpose bucket permissions - To perform a multipart upload with encryption using an Key Management Service key, the requester must have permission to the kms:Decrypt
and kms:GenerateDataKey
actions on the key. The requester must also have permissions for the kms:GenerateDataKey
action for the CreateMultipartUpload
API. Then, the requester needs permissions for the kms:Decrypt
action on the UploadPart
and UploadPartCopy
APIs. These permissions are required because Amazon S3 must decrypt and read data from the encrypted file parts before it completes the multipart upload. For more information about KMS permissions, see Protecting data using server-side encryption with KMS in the Amazon S3 User Guide . For information about the permissions required to use the multipart upload API, see Multipart upload and permissions and Multipart upload API and permissions in the Amazon S3 User Guide .
Directory bucket permissions - To grant access to this API operation on a directory bucket, we recommend that you use the ` CreateSession
https://docs.aws.amazon.com/AmazonS3/latest/API/API_CreateSession.html`__ API operation for session-based authorization. Specifically, you grant the s3express:CreateSession
permission to the directory bucket in a bucket policy or an IAM identity-based policy. Then, you make the CreateSession
API call on the bucket to obtain a session token. With the session token in your request header, you can make API requests to this operation. After the session token expires, you make another CreateSession
API call to generate a new session token for use. Amazon Web Services CLI or SDKs create session and refresh the session token automatically to avoid service interruptions when a session expires. For more information about authorization, see ` CreateSession
https://docs.aws.amazon.com/AmazonS3/latest/API/API_CreateSession.html`__ . If the object is encrypted with SSE-KMS, you must also have the kms:GenerateDataKey
and kms:Decrypt
permissions in IAM identity-based policies and KMS key policies for the KMS key.
Data integrity
General purpose bucket - To ensure that data is not corrupted traversing the network, specify theContent-MD5
header in the upload part request. Amazon S3 checks the part data against the provided MD5 value. If they do not match, Amazon S3 returns an error. If the upload request is signed with Signature Version 4, then Amazon Web Services S3 uses thex-amz-content-sha256
header as a checksum instead ofContent-MD5
. For more information see Authenticating Requests: Using the Authorization Header (Amazon Web Services Signature Version 4) .
Directory buckets - MD5 is not supported by directory buckets. You can use checksum algorithms to check object integrity.
Encryption
For more information, see Using Server-Side Encryption in the Amazon S3 User Guide .
Directory buckets - For directory buckets, there are only two supported options for server-side encryption: server-side encryption with Amazon S3 managed keys (SSE-S3) (AES256
) and server-side encryption with KMS keys (SSE-KMS) (aws:kms
).
Special errors
Error Code: NoSuchUpload
HTTP Host header syntax
Directory buckets - The HTTP Host header syntax is `` Bucket_name .s3express-az_id .*region* .amazonaws.com`` .

--body
(streaming blob)
Object data.
Note
This argument is of type: streaming blob. Its value must be the path to a file (e.g.path/to/file
) and must not be prefixed withfile://
orfileb://
--bucket
(string)
The name of the bucket to which the multipart upload was initiated.
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 .
Note
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 .
--content-length
(long)
Size of the body in bytes. This parameter is useful when the size of the body cannot be determined automatically.
--content-md5
(string)
The base64-encoded 128-bit MD5 digest of the part data. This parameter is auto-populated when using the command from the CLI. This parameter is required if object lock parameters are specified.
Note
This functionality is not supported for directory buckets.
--checksum-algorithm
(string)
Indicates the algorithm used to create the checksum for the object when you use the SDK. This header will not provide any additional functionality if you don't use the SDK. When you send this header, there must be a corresponding
x-amz-checksum
orx-amz-trailer
header sent. Otherwise, Amazon S3 fails the request with the HTTP status code400 Bad Request
. For more information, see Checking object integrity in the Amazon S3 User Guide .If you provide an individual checksum, Amazon S3 ignores any provided
ChecksumAlgorithm
parameter.This checksum algorithm must be the same for all parts and it match the checksum value supplied in the
CreateMultipartUpload
request.Possible values:
CRC32
CRC32C
SHA1
SHA256
--checksum-crc32

(string)
Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. If either the source or destination S3 bucket has Requester Pays enabled, the requester will pay for corresponding charges to copy the object. For information about downloading objects from Requester Pays buckets, see Downloading Objects in Requester Pays Buckets in the Amazon S3 User Guide .
Note
This functionality is not supported for directory buckets.Possible values:
requester
--expected-bucket-owner
(string)
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 code403 Forbidden
(access denied).

--cli-connect-timeout
(int)
The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.
To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.
Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal's quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .
The following command uploads the first part in a multipart upload initiated with the create-multipart-upload
command:
aws s3api upload-part --bucket my-bucket --key 'multipart/01' --part-number 1 --body part01 --upload-id "dfRtDYU0WWCCcH43C3WFbkRONycyCpTJJvxu2i5GYkZljF.Yxwh6XG7WfS2vC4to6HiV6Yjlx.cph0gtNBtJ8P3URCSbB7rjxI5iEwVDmgaXZOGgkk5nVTW16HOQ5l0R"
The body
option takes the name or path of a local file for upload (do not use the file:// prefix). The minimum part size is 5 MB. Upload ID is returned by create-multipart-upload
and can also be retrieved with list-multipart-uploads
. Bucket and key are specified when you create the multipart upload.
Output:
{
