Invoke Web Service operation

A web service client that invokes a web service operation and saves the response as process data, including attachments. Invoke Web Service interacts with web services by sending and receiving SOAP messages. For authentication, this operation supports HTTP Basic Authentication and HTTPS authentication.

This operation supports sending inline MIME, SwaRef, and base64, and MTOM attachments with SOAP messages using the WS-Attachment protocol. DIME attachments and MTOM attachments sent as base64-encoded byte array that are embedded in the SOAP XML are not supported.

Use the Invoke Web Service operation to call a web service to retrieve data that your process requires. For example, a purchase order process uses a web service to retrieve the name of a customer, their mailing address, and other billing information.
