Outgoing connector requests are associated with the combination of a Connector Rule and Connector Activity.
A Connector Rule is specific to the integration protocol, such as Rule-Connect-SOAP for SOAP and Rule-Connect-SQL for SQL. A Connector Rule contains protocol specific configuration, such as the endpoint URL for a SOAP Connector and SQL statements for the SQL Connector.
A Connector Rule is executed via an Activity method. The Activity executing the Connector Rule is called the Connector Activity. This activity prepares the Request parameters and processes the Response parameters. The Activity can be called from anywhere activities are called and is often configured via integrator shapes in a flow rule.
Like Services, PRPC contains many wizards that help support a variety of Connectors. Through the SOAP Connector Wizard, PRPC can inspect a WSDL from an external system, generating supporting rules in PRPC. Through the SQL Connector Wizard, PRPC can inspect metadata from external databases, generating supporting rules, including SQL statements.
Depending on the integration method chosen, some connectors can be generated via a wizard and others are manually created.
