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.

groups, see Common operation properties.

Web Service Response propertiesProperties for saving the web service response message.

AttachmentsThe
location in the process data model to save documents that are attached
to the response message. The data type is list,
which holds document values.
CDATA ListThe location to save text that is located inside
CDATA sections in the web service response. The data type is list
which holds document values. The list contains a document value

When
you save CDATA selections in a list of documents, you do not have
to parse the web service response to access the text. For example,
when LiveCycle web services return XML code in their response, it
is located in a CDATA section. Other web services can include other
types of data inside CDATA sections.
