Reference: Supported channel parameters

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.

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.
