Techniques are provided for extending a WS-enabled scanner. A client device sends a request for multiple scan ticket templates that the WS-enabled scanner maintains. A WS scan module, executing on the scanner, receives the request and forwards the request to a scan templates handler (STH). The STH invokes a routine of a scan templates manager (STM). The STM retrieves, in response to the invocation of the routine, a plurality of scan ticket templates. The STM sends the plurality of scan ticket templates to the STH, which forwards the plurality to the WS scan module. The WS scan module composes a response message that includes the plurality of scan ticket templates and sends the response message to the client device.
