Snapshots save the specific results when a mashable or mashup is run. To use a snapshot in a basic app, share a snapshot with other users or easily use a snapshot in a mashup in Wires, you must Register a Snapshot as a Mashable.
Note:
Presto developers can use snapshots directly in mashups using EMML and the Presto
Snapshot API. Developers can also create custom apps that use snapshots directly through this API.
