# get-attachment-upload-links

## Description

Returns one or more presigned upload URLs for uploading a large file attachment to a support case by using a multipart upload workflow. The maximum file size that you can upload with this workflow is 150 MB, and parts can be up to 100 MB each. Initiate a new upload by providing `fileName` and `fileSizeBytes` ; the response returns a unique `uploadId` , the part size, the total number of parts, and a list of presigned upload URLs for the requested range of parts. A maximum of 10 upload URLs are returned per call. To retrieve more upload URLs for an upload that’s already in progress, call `GetAttachmentUploadLinks` again with the existing `uploadId` and a new `uploadRange` .

Upload each part to its presigned URL by using HTTP `PUT` and capture the ETag from the response. After you upload all parts, call  CompleteAttachmentUpload with the `uploadId` and the list of part indexes and ETags to finalize the upload. You can then attach the upload to a case by passing the `uploadId` in the `uploadIds` parameter of  CreateCase or  AddCommunicationToCase . To monitor progress before completion, call  DescribeAttachmentUploadStatus .

#### NOTE
* You must have an Amazon Web Services Business Support+, Amazon Web Services Enterprise Support, or Amazon Web Services Unified Operations plan to use the Amazon Web Services Support API. If you’re in an Amazon Web Services Region that doesn’t offer one of these Amazon Web Services Support plans, or if you haven’t transitioned to one of these plans, you can use the Amazon Web Services Support API with a Business, Enterprise On-Ramp, or Enterprise Support plan.
* If you call the Amazon Web Services Support API from an account that doesn’t have an Amazon Web Services Business Support+, Amazon Web Services Enterprise Support, or Amazon Web Services Unified Operations plan, the `SubscriptionRequiredException` error message appears. For information about changing your support plan, see [Amazon Web Services Support](http://aws.amazon.com/premiumsupport/) .

## Options

`--file-name` (string) [required]

> The name of the file to upload, including the file extension. This value is required when you initiate a new upload.

`--file-size-bytes` (long)

> The total size of the file in bytes. The service uses this value to calculate the total number of parts and the size of each part. Required when you initiate a new upload (when `uploadId` isn’t provided). Valid range: 1 to 157,286,400 bytes (approximately 150 MB).

> Constraints:

> * min: `1`
> * max: `157286400`

`--upload-id` (string)

> The unique identifier of an in-progress multipart upload, returned by a previous call to `GetAttachmentUploadLinks` . Specify `uploadId` to retrieve additional presigned upload URLs for an upload that has already been initiated. Required when `fileSizeBytes` isn’t provided. Length: 1 to 2,048 characters.

> Constraints:

> * min: `1`
> * max: `2048`

`--upload-range` (structure)

> The range of part indexes for which to return presigned upload URLs. Use this parameter to page through the upload URLs for a large file across multiple calls. If you omit this parameter, the service determines the range to return.

> startIndex -> (integer) [required]

> > The starting part index of the range, inclusive. Part indexes start at 1.

> > Constraints:

> > * min: `1`

> endIndex -> (integer)

> > The ending part index of the range, exclusive. The range is half-open: `startIndex` is inclusive and `endIndex` is exclusive. For example, a range with `startIndex` of 1 and `endIndex` of 4 requests URLs for parts 1, 2, and 3. The range size (`endIndex` - `startIndex` ) must not exceed 10. If you omit `endIndex` , the service defaults to `startIndex` + 10, capped by the total number of parts.

> > Constraints:

> > * min: `2`

Shorthand Syntax:

```
startIndex=integer,endIndex=integer
```

JSON Syntax:

```json
{
  "startIndex": integer,
  "endIndex": integer
}
```

`--dry-run` | `--no-dry-run` (boolean)

> Specifies whether to validate the request without actually generating upload URLs. When set to `true` , the request is validated but no URLs are returned, and the operation returns a `DryRunOperationException` . When omitted or set to `false` , the request runs normally.

`--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. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

## Global Options

`--debug` (boolean)

Turn on debug logging.

`--endpoint-url` (string)

Override command’s default URL with the given URL.

`--no-verify-ssl` (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

`--no-paginate` (boolean)

Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

`--output` (string)

The formatting style for command output.

* json
* text
* table
* yaml
* yaml-stream
* off

`--query` (string)

A JMESPath query to use in filtering the response data.

`--profile` (string)

Use a specific profile from your credential file.

`--region` (string)

The region to use. Overrides config/env settings.

`--version` (string)

Display the version of this tool.

`--color` (string)

Turn on/off color output.

* on
* off
* auto

`--no-sign-request` (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

`--ca-bundle` (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

`--cli-read-timeout` (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

`--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.

`--cli-binary-format` (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob `fileb://` will always be treated as binary and use the file contents directly regardless of the `cli-binary-format` setting. When using `file://` the file contents will need to properly formatted for the configured `cli-binary-format`.

* base64
* raw-in-base64-out

`--no-cli-pager` (boolean)

Disable cli pager for output.

`--cli-auto-prompt` (boolean)

Automatically prompt for CLI input parameters.

`--no-cli-auto-prompt` (boolean)

Disable automatically prompt for CLI input parameters.

`--cli-error-format` (string)

The formatting style for error output. By default, errors are displayed in enhanced format.

* legacy
* json
* yaml
* text
* table
* enhanced

`--help` (boolean)

Display help for the command/subcommand.

## Output
