The Create customer request endpoint in the Jira Service Desk REST API has an option to pass a channel string attribute in the payload. The docs say:
(Experimental) Shows extra information for the request channel.
Passing any string seems to be accepted but I cannot find where that would be exposed in the UI or in the request-channel-type attribute (this still seems to be fixed to the few hard-coded values).
Does anyone know how this attribute works or where I can find additional information about it?
