In CAF,web application page I have created web service connector for one flow service. In other page how can i use same web service connector without recreating.
If i recreate its working but if i add like reference of web service connector, its not working.

How you are calling this webservice...? Auto refresh will not work for referenced services...

after adding the reference , have you given the credentials and end point address .. in case there is any mappings to input signature , please update
them as well ....also click on connector in bindins view and share the
snapshot of bindings ....
