   END RECORD

PUBLIC FUNCTION UpdateUserProfile(
    id STRING ATTRIBUTE(WSParam),
    thisUser profileType )
  ATTRIBUTES (WSPut,
              WSPath="/users/{id}",
              WSThrows='404:user not found')
  RETURNS STRING
    DEFINE ret STRING
    # ... function code  ...
    LET ret = SFMT("Updated user with ID: %1",id)
    RETURN ret
END FUNCTION

In this example, a resource is updated. thisUser is data passed in the message body in either JSON or XML format. An example of the resource URL shows xxx as the user id replaced in the 4GL function.
