How to pass arguments from the slash command to the payload?

[everspader]

How would you pass text or arguments from the slash command to the payload of the request?
Let's say you want to use a /deploy command and pass arguments for the environment or version of the deployment to be later used inside the GitHub action.

/deploy [environment] [version] ...

Hi @everspader, I take it that you found my example from reading Triggering a GitHub Actions Workflow with a Slack Slash Command. So I will then assume you are triggering the GitHub action via AWS' API Gateway.

Given the following mapping template:

{
    "event_type": "slack-deploy-command", 
    "client_payload":
    {
        "data": {
            #foreach( $token in $input.body.split('&') )
                #set( $keyVal = $token.split('=') )
                #set( $keyValSize = $keyVal.size() )
                #if( $keyValSize >= 1 )
                    #set( $key = $util.urlDecode($keyVal[0]) )
                    #if( $keyValSize >= 2 )
                        #set( $val = $util.urlDecode($keyVal[1]) )
                    #else
                        #set( $val = '' )
                    #end
                    "$key": "$val"#if($foreach.hasNext),#end
                #end
            #end
        }
    }
}

You retrieve and parse the arguments via ${{ github.event.client_payload.data.text }}.
