You'll need to use the SOAP action http://archer-tech.com/webservices/CreateRecords.
I typically use a mix of SOAP and REST calls. Initially the API was SOAP, and that's where most of the data manipulation happens. REST has newer functions to retrieve meta-data, user information, advanced workflow calls, etc.. After you establish the SOAP connection, create a REST connection but send it the session ID from the SOAP call. Then you can use both without invalidating the session token.
The API resources available in the administration list under Integration are very helpful for finding which calls you need. You can also download the API documentation PDFs (again, you'll want both the original "web services API" and the "REST API" documents). Does anyone have current links for these? I'm only seeing links that go back to the RSA site. Thanks.
