WSDL (Web Service Description Language)


The Base component implements functionality to call web APIs, and use them in integration flows, using a Web Service Description Language (WSDL) connector.

The WSDL connector is mainly used to reverse-engineer and call SOAP APIs. It also works with REST APIs, and is useful for legacy APIs that do not provide their own service description. However, you should use the dedicated HTTP REST connector for REST workflows where possible.


To use WSDL metadata with REST workflows, see the legacy documentation here.
