NOTE: MetaMessage is now CoverCard™.
The MetaMessage resource is special in the sense that it is only created/read/updated/destroyed through a Destination resource.
The workflow to create a Meta Message on all future resources is done by passing up:
metaMessage: <object> an object of attributes to put on the MetaMessage
When updating an Destination with a MetaMessage that does not currently have one, a new MetaMessage will be created and bound.
A MetaMessage can be passed the following arguments:
| Parameter | Example | Notes |
|---|---|---|
| "title" | "The title displayed on the Meta Message page" | String - Required. |
| "description" | "The description that displays on the meta message page" | String - Optional. |
| "imageUrl" | "https://url.to.another.image" | String - Optional. |
