[Webservice] Log and Monitoring ?

Hi Guys,

I implemented a Webservice who communicate with an external environment. My Webservice has been developed to be executed when a Module Function is called. 

I have no any access of the external environment, and I would like to know how can I make sure that my Webservice is called by the MF and my data sent really?

Are there some Monitoring Transactions ?

Thank you very much.

Best Regards.

Rachid.
