# AddCommunicationToCase
<a name="API_AddCommunicationToCase"></a>

Adds additional customer communication to a 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.

**Important**  
 AWS Support automatically redacts sensitive information from support cases to protect your data. The following information is replaced with `[REDACTED_BY_AWS]` and is not stored:  
 AWS secret keys - The complete key is replaced. Example: `[REDACTED_BY_AWS]` 
Private keys - The complete key is replaced. Example: `[REDACTED_BY_AWS]` 
Credit card numbers - The number is redacted, but the last 4 digits remain. Example: `[REDACTED_BY_AWS]-7016` 
This sensitive information is never required by AWS Support.

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