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.
