Built-in connections

A connection is a saved, authenticated link to an external system, referenced by the nodes that need it instead of each node carrying its own credentials. Most connection types belong to a particular integration—see Integrations. One is built in and belongs to no integration at all.

For how connections are created, connected, and reconnected, see Connections.
