connector

The term connector is used in the following two ways.

On a flow diagram, a connector is a line that connects two shapes. Typically, connectors leaving an assignment shape represent flow actions. Other connectors might link to a When condition rule.
A connector is a programmatic component that defines and implements an interface between a Pega Platform application that is acting as a client, and an external system that is acting as a server. A connector is implemented by any of the rule types in the Integration Connectors category.
You can use the Connector and Metadata wizard to develop many connectors without entering class rules, properties, or connector rules. You can also create SOAP, REST, and SAP connectors directly from the Connectors landing page.
