Additional URL configuration

Mattermost provides functionality to post as another user or to another channel, compared to the webhook configuration.
To do this, you can add a user and/or channel to the service URL.

             └──────────┘                 └────────────────────────┘ └─────────────┘
                 user                               token                channel

Passing parameters via code

If you want to, you also have the possibility to pass parameters to the send function.
The following example contains all parameters that are currently supported.

params := (*types.Params)(
        "username": "overwriteUserName",
        "channel": "overwriteChannel",
        "icon": "overwriteIcon",

service.Send("this is a message", params)

This will overwrite any options, that you passed via URL.
