Get a snippet

Fetches a single snippet by id. Unlike List snippets, this endpoint always returns the full content and document — no include_content flag needed.

Use this when you have an id (e.g. stored from a prior create call) and need the current key and body — for example, to preview the resolved HTML or confirm a snippet still exists before referencing it as {{ snippet.key }} in a broadcast or sequence email. See Create a snippet for the snippet model.
