Application users must currently be added via SQL using the <executeSQLUpdate> request. Please see the CM Data Dictionary for details on the tables/fields involved in order to help you build the SQL statement.

Note, however that the password/pin fields should not be specified or updated via SQL, as they require special encryption hashing by the AXL layer. After the application user record has been created via <executeSQLUpdate>, you will need to use the <updateAppUser> request to update the password and pin fields.
