# add-communication-to-case

## Description

Adds additional customer communication to a Amazon Web Services Support case. Use the `caseId` parameter to identify the case to which to add communication. To list a set of email addresses to copy on the communication, use the `ccEmailAddresses` parameter. The `communicationBody` value contains the text of the communication.

To attach files larger than 5 MB to the communication, use the `uploadIds` parameter.

#### WARNING
Amazon Web Services Support automatically redacts sensitive information from support cases to protect your data. The following information is replaced with `[REDACTED_BY_Amazon Web Services]` and is not stored:

* Amazon Web Services secret keys - The complete key is replaced. Example: `[REDACTED_BY_Amazon Web Services]`
* Private keys - The complete key is replaced. Example: `[REDACTED_BY_Amazon Web Services]`
* Credit card numbers - The number is redacted, but the last 4 digits remain. Example: `[REDACTED_BY_Amazon Web Services]-7016`

This sensitive information is never required by Amazon Web Services Support.

#### 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

`--case-id` (string)

> The support case ID requested or returned in the call. The case ID is an alphanumeric string formatted as shown in this example: case-*12345678910-exen-2025-c4c1d2bf33c5cf47*

`--communication-body` (string) [required]

> The body of an email communication to add to the support case.

> Constraints:

> * min: `1`
> * max: `8000`

`--cc-email-addresses` (list)

> The email addresses in the CC line of an email to be added to the support case.

> Constraints:

> * min: `0`
> * max: `10`

> (string)

Syntax:

```
"string" "string" ...
```

`--attachment-set-id` (string)

> The ID of a set of one or more attachments for the communication to add to the case. Create the set by calling  AddAttachmentsToSet . Each attachment in the set must be 5 MB or smaller. To attach files larger than 5 MB, use `uploadIds` .

`--upload-ids` (list)

> A list of upload IDs that identify attachments to add to the case. Each `uploadId` is returned by the  GetAttachmentUploadLinks operation. The upload must reach the `attachment-ready` state by calling  CompleteAttachmentUpload before it can be passed here. Use `uploadIds` to attach files of any supported size, including files larger than 5 MB.

> Constraints:

> * min: `0`
> * max: `10`

> (string)

> > Constraints:

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

Syntax:

```
"string" "string" ...
```

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

> Specifies whether to validate the request without actually adding the communication to the case. When set to `true` , the request is validated but the communication isn’t added, 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

## Examples

#### NOTE
To use the following examples, you must have the AWS CLI installed and configured. See the [Getting started guide](https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-getting-started.html) 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](https://docs.aws.amazon.com/cli/latest/userguide/cli-usage-parameters-quoting-strings.html) in the *AWS CLI User Guide* .

**To add communication to a case**

The following `add-communication-to-case` example adds communications to a support case in your AWS account.

```bash
aws support add-communication-to-case \
    --case-id "case-12345678910-2013-c4c1d2bf33c5cf47" \
    --communication-body "I'm attaching a set of images to this case." \
    --cc-email-addresses "myemail@example.com" \
    --attachment-set-id "as-2f5a6faa2a4a1e600-mu-nk5xQlBr70-G1cUos5LZkd38KOAHZa9BMDVzNEXAMPLE"
```

Output:

```json
{
    "result": true
}
```

For more information, see [Case management](https://docs.aws.amazon.com/awssupport/latest/user/case-management.html) in the *AWS Support User Guide*.

## Output

result -> (boolean)

> True if  AddCommunicationToCase succeeds. Otherwise, returns an error.
