Snaps are the building blocks of a pipeline. Each Snap performs a single function, such as read, parse, transform or write data. You can view the Snaps available to you (or your account) in the Snaps catalog, on the left-hand side of the SnapLogic Designer. You can drag a Snap from the Snaps catalog on to the Canvas to use it in a pipeline. By default, the Snaps catalog contains a set of core Snaps available to all users. You can add premium or custom Snaps by installing them in the SnapLogic Classic Manager or Admin Manager on the Snap Packs (project level) page.
