After the session token expires, you make another <code>CreateSession</code> API call to generate a new session token for use. \nAmazon Web Services CLI or SDKs create session and refresh the session token automatically to avoid service interruptions when a session expires.

While processing is in progress, Amazon S3 periodically sends white\n         space characters to keep the connection from timing out. A request could fail after the\n         initial 200 OK response has been sent. This means that a <code>200 OK</code> response can\n         contain either a success or an error. If you call the S3 API directly, make sure to design\n         your application to parse the contents of the response and handle it appropriately.

After Amazon S3 begins processing the request, it sends an HTTP response header that\n         specifies a <code>200 OK</code> response. While processing is in progress, Amazon S3 periodically sends white\n         space characters to keep the connection from timing out. A request could fail after the\n         initial <code>200 OK</code> response has been sent. This means that a <code>200 OK</code> response can\n         contain either a success or an error. The error response might be embedded in the <code>200 OK</code> response. \n         If you call this API operation directly, make sure to design\n         your application to parse the contents of the response and handle it appropriately. If you\n         use Amazon Web Services SDKs, SDKs handle this condition. The SDKs detect the embedded error and apply\n         error handling per your configuration settings (including automatically retrying the\n         request as appropriate). If the condition persists, the SDKs throw an exception (or, for\n         the SDKs that don't use exceptions, they return an error). </p>\n         <p>Note that if <code>CompleteMultipartUpload</code> fails, applications should be prepared\n         to retry the failed requests. For more information, see <a href=\"https://docs.aws.amazon.com/AmazonS3/latest/dev/ErrorBestPractices.html\">Amazon S3 Error Best\n         Practices</a>.</p>\n         <important>\n            <p>You can't use <code>Content-Type: application/x-www-form-urlencoded</code> for the \n            CompleteMultipartUpload requests. Also, if you don't provide a\n               <code>Content-Type</code> header, <code>CompleteMultipartUpload</code> can still return a <code>200\n            OK</code> response.</p>\n         </important>\n         <p>For more information about multipart uploads, see <a href=\"https://docs.aws.amazon.com/AmazonS3/latest/dev/uploadobjusingmpu.html\">Uploading Objects Using Multipart\n         Upload</a> in the <i>Amazon S3\n            User Guide</i>.</p>\n         <note>\n            <p>\n               <b>Directory buckets</b> -  For directory buckets, you must make requests for this API operation to the Zonal endpoint.

If the error occurs before the copy action starts, you receive a\n         standard Amazon S3 error. If the error occurs during the copy operation, the error response is\n         embedded in the <code>200 OK</code> response. This means that a <code>200 OK</code>\n         response can contain either a success or an error. If you call the S3 API directly, make\n         sure to design your application to parse the contents of the response and handle it\n         appropriately. If you use Amazon Web Services SDKs, SDKs handle this condition. The SDKs detect the\n         embedded error and apply error handling per your configuration settings (including\n         automatically retrying the request as appropriate). If the condition persists, the SDKs\n         throws an exception (or, for the SDKs that don't use exceptions, they return the\n         error).</p>\n         <p>If the copy is successful, you receive a response with information about the copied\n         object.</p>\n         <note>\n            <p>If the request is an HTTP 1.1 request, the response is chunk encoded. If it were not,\n            it would not contain the content-length, and you would need to read the entire\n            body.</p>\n         </note>\n         <p>The copy request charge is based on the storage class and Region that you specify for\n         the destination object.

By default, all buckets have a\n                  base level of encryption configuration that uses server-side encryption with Amazon S3\n                  managed keys (SSE-S3). If the destination bucket has a default encryption\n                  configuration that uses server-side encryption with Key Management Service (KMS) keys\n                  (SSE-KMS), dual-layer server-side encryption with Amazon Web Services KMS keys (DSSE-KMS), or\n                  server-side encryption with customer-provided encryption keys (SSE-C), Amazon S3 uses\n                  the corresponding KMS key, or a customer-provided key to encrypt the target\n                  object copy.</p>\n               <p>When you perform a <code>CopyObject</code> operation, if you want to use a\n                  different type of encryption setting for the target object, you can use other\n                  appropriate encryption-related headers to encrypt the target object with a\n                  KMS key, an Amazon S3 managed key, or a customer-provided key. With server-side\n                  encryption, Amazon S3 encrypts your data as it writes your data to disks in its data\n                  centers and decrypts the data when you access it. If the encryption setting in\n                  your request is different from the default encryption configuration of the\n                  destination bucket, the encryption setting in your request takes precedence. If\n                  the source object for the copy is stored in Amazon S3 using SSE-C, you must provide the\n                  necessary encryption information in your request so that Amazon S3 can decrypt the\n                  object for copying.

Amazon S3 encrypts your data as it\n         writes it to disks in its data centers and decrypts it when you access it. Amazon S3\n         automatically encrypts all new objects that are uploaded to an S3 bucket. When doing a\n         multipart upload, if you don't specify encryption information in your request, the\n         encryption setting of the uploaded parts is set to the default encryption configuration of\n         the destination bucket. By default, all buckets have a base level of encryption\n         configuration that uses server-side encryption with Amazon S3 managed keys (SSE-S3). If the\n         destination bucket has a default encryption configuration that uses server-side encryption\n         with an Key Management Service (KMS) key (SSE-KMS), or a customer-provided encryption key (SSE-C),\n         Amazon S3 uses the corresponding KMS key, or a customer-provided key to encrypt the uploaded\n         parts. When you perform a CreateMultipartUpload operation, if you want to use a different\n         type of encryption setting for the uploaded parts, you can request that Amazon S3 encrypts the\n         object with a KMS key, an Amazon S3 managed key, or a customer-provided key. If the encryption\n         setting in your request is different from the default encryption configuration of the\n         destination bucket, the encryption setting in your request takes precedence. If you choose\n         to provide your own encryption key, the request headers you provide in <a href=\"https://docs.aws.amazon.com/AmazonS3/latest/API/API_UploadPart.html\">UploadPart</a>\n         and <a href=\"https://docs.aws.amazon.com/AmazonS3/latest/API/API_UploadPartCopy.html\">UploadPartCopy</a> requests must match the headers you used in the request to\n         initiate the upload by using <code>CreateMultipartUpload</code>. You can request that Amazon S3\n         save the uploaded parts encrypted with server-side encryption with an Amazon S3 managed key\n         (SSE-S3), an Key Management Service (KMS) key (SSE-KMS), or a customer-provided encryption key\n         (SSE-C). </p>\n         <p>To perform a multipart upload with encryption by using an Amazon Web Services KMS key, the requester\n         must have permission to the <code>kms:Decrypt</code> and <code>kms:GenerateDataKey*</code>\n         actions on the key. These permissions are required because Amazon S3 must decrypt and read data\n         from the encrypted file parts before it completes the multipart upload.

The option you use depends on\n                  whether you want to use KMS keys (SSE-KMS) or provide your own encryption keys\n                  (SSE-C).</p>\n               <ul>\n                  <li>\n                     <p>Use KMS keys (SSE-KMS) that include the Amazon Web Services managed key\n                           (<code>aws/s3</code>) and KMS customer managed keys stored in Key Management Service (KMS) –\n                        If you want Amazon Web Services to manage the keys used to encrypt data, specify the\n                        following headers in the request.</p>\n                     <ul>\n                        <li>\n                           <p>\n                              <code>x-amz-server-side-encryption</code>\n                           </p>\n                        </li>\n                        <li>\n                           <p>\n                              <code>x-amz-server-side-encryption-aws-kms-key-id</code>\n                           </p>\n                        </li>\n                        <li>\n                           <p>\n                              <code>x-amz-server-side-encryption-context</code>\n                           </p>\n                        </li>\n                     </ul>\n                     <note>\n                        <p>If you specify <code>x-amz-server-side-encryption:aws:kms</code>, but\n                           don't provide <code>x-amz-server-side-encryption-aws-kms-key-id</code>,\n                           Amazon S3 uses the Amazon Web Services managed key (<code>aws/s3</code> key) in KMS to\n                           protect the data.</p>\n                     </note>\n                     <important>\n                        <p>All <code>GET</code> and <code>PUT</code> requests for an object\n                           protected by KMS fail if you don't make them by using Secure Sockets\n                           Layer (SSL), Transport Layer Security (TLS), or Signature Version\n                           4.</p>\n                     </important>\n                     <p>For more information about server-side encryption with KMS keys\n                        (SSE-KMS), see <a href=\"https://docs.aws.amazon.com/AmazonS3/latest/userguide/UsingKMSEncryption.html\">Protecting Data\n                           Using Server-Side Encryption with KMS keys</a>.</p>\n                  </li>\n                  <li>\n                     <p>Use customer-provided encryption keys (SSE-C) – If you want to manage\n                        your own encryption keys, provide all the following headers in the\n                        request.</p>\n                     <ul>\n                        <li>\n                           <p>\n                              <code>x-amz-server-side-encryption-customer-algorithm</code>\n                           </p>\n                        </li>\n                        <li>\n                           <p>\n                              <code>x-amz-server-side-encryption-customer-key</code>\n                           </p>\n                        </li>\n                        <li>\n                           <p>\n                              <code>x-amz-server-side-encryption-customer-key-MD5</code>\n                           </p>\n                        </li>\n                     </ul>\n                     <p>For more information about server-side encryption with customer-provided\n                        encryption keys (SSE-C), see <a href=\"https://docs.aws.amazon.com/AmazonS3/latest/userguide/ServerSideEncryptionCustomerKeys.html\">\n                           Protecting data using server-side encryption with customer-provided\n                           encryption keys (SSE-C)</a>.</p>\n                  </li>\n               </ul>\n            </dd>\n            <dt>Access-Control-List (ACL)-Specific Request Headers</dt>\n            <dd>\n               <p>You also can use the following access control–related headers with this\n                  operation.

Specifically, you grant the <code>s3express:CreateSession</code> permission to the directory bucket in a bucket policy or an IAM identity-based policy. Then, you make the <code>CreateSession</code> 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 <code>CreateSession</code> API call to generate a new session token for use. \nAmazon Web Services CLI or SDKs create session and refresh the session token automatically to avoid service interruptions when a session expires.

Amazon S3 encrypts your data as it\n                        writes it to disks in its data centers and decrypts it when you access it. Amazon S3\n                        automatically encrypts all new objects that are uploaded to an S3 bucket. When doing a\n                        multipart upload, if you don't specify encryption information in your request, the\n                        encryption setting of the uploaded parts is set to the default encryption configuration of\n                        the destination bucket. By default, all buckets have a base level of encryption\n                        configuration that uses server-side encryption with Amazon S3 managed keys (SSE-S3). If the\n                        destination bucket has a default encryption configuration that uses server-side encryption\n                        with an Key Management Service (KMS) key (SSE-KMS), or a customer-provided encryption key (SSE-C),\n                        Amazon S3 uses the corresponding KMS key, or a customer-provided key to encrypt the uploaded\n                        parts. When you perform a CreateMultipartUpload operation, if you want to use a different\n                        type of encryption setting for the uploaded parts, you can request that Amazon S3 encrypts the\n                        object with a different encryption key (such as an Amazon S3 managed key, a KMS key, or a customer-provided key). When the encryption\n                        setting in your request is different from the default encryption configuration of the\n                        destination bucket, the encryption setting in your request takes precedence.

Specifically, you grant <code>s3express:CreateSession</code> permission to a\n         bucket in a bucket policy or an IAM identity-based policy. Then, you use IAM credentials to make the\n            <code>CreateSession</code> API request on the bucket, which returns temporary security\n         credentials that include the access key ID, secret access key, session token, and\n         expiration. These credentials have associated permissions to access the Zonal endpoint APIs. After\n         the session is created, you don’t need to use other policies to grant permissions to each\n         Zonal endpoint API individually. Instead, in your Zonal endpoint API requests, you sign your requests by\n         applying the temporary security credentials of the session to the request headers and\n         following the SigV4 protocol for authentication. You also apply the session token to the\n            <code>x-amz-s3session-token</code> request header for authorization. Temporary security\n         credentials are scoped to the bucket and expire after 5 minutes. After the expiration time,\n         any calls that you make with those credentials will fail. You must use IAM credentials\n         again to make a <code>CreateSession</code> API request that generates a new set of\n         temporary credentials for use. Temporary credentials cannot be extended or refreshed beyond\n         the original specified interval.</p>\n         <p>If you use Amazon Web Services SDKs, SDKs handle the session token refreshes automatically to avoid\n         service interruptions when a session expires.

Then, you make the <code>CreateSession</code> 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 <code>CreateSession</code> API call to generate a new session token for use. \nAmazon Web Services CLI or SDKs create session and refresh the session token automatically to avoid service interruptions when a session expires.

For more information\n         about permissions, see <a href=\"https://docs.aws.amazon.com/AmazonS3/latest/userguide/using-with-s3-actions.html#using-with-s3-actions-related-to-bucket-subresources\">Permissions Related to Bucket Subresource Operations</a> and <a href=\"https://docs.aws.amazon.com/AmazonS3/latest/userguide/s3-access-control.html\">Managing\n            Access Permissions to Your Amazon S3 Resources</a>.</p>\n         <p> The Transfer Acceleration state of a bucket can be set to one of the following two\n         values:</p>\n         <ul>\n            <li>\n               <p> Enabled – Enables accelerated data transfers to the bucket.</p>\n            </li>\n            <li>\n               <p> Suspended – Disables accelerated data transfers to the bucket.</p>\n            </li>\n         </ul>\n         <p>The <a href=\"https://docs.aws.amazon.com/AmazonS3/latest/API/API_GetBucketAccelerateConfiguration.html\">GetBucketAccelerateConfiguration</a> action returns the transfer acceleration state\n         of a bucket.</p>\n         <p>After setting the Transfer Acceleration state of a bucket to Enabled, it might take up\n         to thirty minutes before the data transfer rates to the bucket increase.</p>\n         <p> The name of the bucket used for Transfer Acceleration must be DNS-compliant and must\n         not contain periods (\".\").</p>\n         <p> For more information about transfer acceleration, see <a href=\"https://docs.aws.amazon.com/AmazonS3/latest/dev/transfer-acceleration.html\">Transfer\n         Acceleration</a>.</p>\n         <p>The following operations are related to\n         <code>PutBucketAccelerateConfiguration</code>:</p>\n         <ul>\n            <li>\n               <p>\n                  <a href=\"https://docs.aws.amazon.com/AmazonS3/latest/API/API_GetBucketAccelerateConfiguration.html\">GetBucketAccelerateConfiguration</a>\n               </p>\n            </li>\n            <li>\n               <p>\n                  <a href=\"https://docs.aws.amazon.com/AmazonS3/latest/API/API_CreateBucket.html\">CreateBucket</a>\n               </p>\n            </li>\n         </ul>",

For example, if you have an existing application\n         that updates a bucket ACL using the request body, then you can continue to use that\n         approach.</p>\n         <important>\n            <p>If your bucket uses the bucket owner enforced setting for S3 Object Ownership, ACLs\n            are disabled and no longer affect permissions. You must use policies to grant access to\n            your bucket and the objects in it. Requests to set ACLs or update ACLs fail and return\n            the <code>AccessControlListNotSupported</code> error code. Requests to read ACLs are\n            still supported. For more information, see <a href=\"https://docs.aws.amazon.com/AmazonS3/latest/userguide/about-object-ownership.html\">Controlling object\n               ownership</a> in the <i>Amazon S3 User Guide</i>.</p>\n         </important>\n         <dl>\n            <dt>Permissions</dt>\n            <dd>\n               <p>You can set access permissions by using one of the following methods:</p>\n               <ul>\n                  <li>\n                     <p>Specify a canned ACL with the <code>x-amz-acl</code> request header. Amazon S3\n                        supports a set of predefined ACLs, known as <i>canned\n                        ACLs</i>. Each canned ACL has a predefined set of grantees and\n                        permissions. Specify the canned ACL name as the value of\n                           <code>x-amz-acl</code>. If you use this header, you cannot use other\n                        access control-specific headers in your request. For more information, see\n                           <a href=\"https://docs.aws.amazon.com/AmazonS3/latest/dev/acl-overview.html#CannedACL\">Canned\n                        ACL</a>.</p>\n                  </li>\n                  <li>\n                     <p>Specify access permissions explicitly with the\n                           <code>x-amz-grant-read</code>, <code>x-amz-grant-read-acp</code>,\n                           <code>x-amz-grant-write-acp</code>, and\n                           <code>x-amz-grant-full-control</code> headers. When using these headers,\n                        you specify explicit access permissions and grantees (Amazon Web Services accounts or Amazon S3\n                        groups) who will receive the permission. If you use these ACL-specific\n                        headers, you cannot use the <code>x-amz-acl</code> header to set a canned\n                        ACL. These parameters map to the set of permissions that Amazon S3 supports in an\n                        ACL.

Only the resource owner (that is, the Amazon Web Services account that created\n                  it) can access the resource. The resource owner can optionally grant access\n                  permissions to others by writing an access policy.

Specifically, the\n         encryption key options are Amazon S3 managed keys (SSE-S3), Amazon Web Services KMS keys (SSE-KMS or\n         DSSE-KMS), and customer-provided keys (SSE-C). Amazon S3 encrypts data with server-side\n         encryption by using Amazon S3 managed keys (SSE-S3) by default. You can optionally tell Amazon S3 to\n         encrypt data at rest by using server-side encryption with other key options.

After the session token expires, you make another <code>CreateSession</code> API call to generate a new session token for use. \nAmazon Web Services CLI or SDKs create session and refresh the session token automatically to avoid service interruptions when a session expires.

Amazon S3 encrypts your data as it\n         writes it to disks in its data centers and decrypts it when you access it. You have three\n         mutually exclusive options to protect data using server-side encryption in Amazon S3, depending\n         on how you choose to manage the encryption keys. Specifically, the encryption key options\n         are Amazon S3 managed keys (SSE-S3), Amazon Web Services KMS keys (SSE-KMS), and Customer-Provided Keys\n         (SSE-C). Amazon S3 encrypts data with server-side encryption using Amazon S3 managed keys (SSE-S3) by\n         default. You can optionally tell Amazon S3 to encrypt data at rest using server-side encryption\n         with other key options. The option you use depends on whether you want to use KMS keys\n         (SSE-KMS) or provide your own encryption key (SSE-C). If you choose to provide your own\n         encryption key, the request headers you provide in the request must match the headers you\n         used in the request to initiate the upload by using <a href=\"https://docs.aws.amazon.com/AmazonS3/latest/API/API_CreateMultipartUpload.html\">CreateMultipartUpload</a>.\n         For more information, go to <a href=\"https://docs.aws.amazon.com/AmazonS3/latest/dev/UsingServerSideEncryption.html\">Using Server-Side\n            Encryption</a> in the <i>Amazon S3 User Guide</i>.</p>\n         <p>Server-side encryption is supported by the S3 Multipart Upload actions.
