messageAttributeNames

The name of the message attribute, where N is the index.

• The name can contain alphanumeric characters and the underscore (_), hyphen (-), and period (.).

• The name is case-sensitive and must be unique among all attribute names for the message.

• The name must not start with AWS-reserved prefixes such as AWS. or Amazon. (or any casing variants).

• The name must not start or end with a period (.), and it should not have periods in succession (..).

• The name can be up to 256 characters long.

When using ReceiveMessage, you can send a list of attribute names to receive, or you can return all of the attributes by specifying All or .* in your request. You can also use all message attributes starting with a prefix, for example bar.*.
