CreateMultipartUploadResponse

If the bucket has a lifecycle rule configured with an action to abort incomplete multipart uploads and the prefix in the lifecycle rule matches the object name in the request, the response includes this header. The header indicates when the initiated multipart upload becomes eligible for an abort operation. For more information, see Aborting Incomplete Multipart Uploads Using a Bucket Lifecycle Configuration in the Amazon S3 User Guide.

This header is returned along with the x-amz-abort-date header. It identifies the applicable lifecycle configuration rule that defines the action to abort incomplete multipart uploads.

The name of the bucket to which the multipart upload was initiated. Does not return the access point ARN or access point alias if used.

Indicates whether the multipart upload uses an S3 Bucket Key for server-side encryption with Key Management Service (KMS) keys (SSE-KMS).

The algorithm that was used to create a checksum of the object.

Object key for which the multipart upload was initiated.

If present, indicates that the requester was successfully charged for the request.

The server-side encryption algorithm used when you store this object in Amazon S3 (for example, AES256, aws:kms).

If server-side encryption with a customer-provided encryption key was requested, the response will include this header to confirm the encryption algorithm that's used.

If server-side encryption with a customer-provided encryption key was requested, the response will include this header to provide the round-trip message integrity verification of the customer-provided encryption key.

If present, indicates the Amazon Web Services KMS Encryption Context to use for object encryption. The value of this header is a base64-encoded UTF-8 string holding JSON with the encryption context key-value pairs.

If present, indicates the ID of the Key Management Service (KMS) symmetric encryption customer managed key that was used for the object.

ID for the initiated multipart upload.
