# Reference: Supported channel parameters
<a name="channel-parameters"></a>

In an AWS Elemental Liveprofile, you can create set up some fields as channel parameters. When a field has a channel parameter, its value is a variables instead of a real value. 

For information about setting up profile fields with channel parameters, see [Working with channel parameters in a profile](creating-a-profile-with-channel-parameters.md).

For a list of fields that support channel parameters, go to the AWS Elemental User Community and search for *supported channel parameters*. You will definitely need this list if you create profiles using the REST API.
