GroupWise Web Services (SOAP)
Server-side SOAP protocol for reading and writing a GroupWise user's mailbox, spoken directly to the GroupWise Post Office Agent over HTTP/HTTPS. 96 documented methods defined in the methods.xsd schema, from loginRequest and getItemsRequest through createItemRequest, sendItemRequest, moveItemsRequest, purgeDeletedItemsRequest and restoreItemRequest, plus a companion GroupWise Web Services Events surface for mailbox event notification. Authentication is a plain-text user credential or a GroupWise Trusted Application name and key, returning a session key that every subsequent call carries. Customer-hosted: the endpoint is the POA, default port 7191.
