Action trigger relating to IC created/changed via web service

Hi all,

We currently have an action triggered when an IC (web) is created or changed. One of the conditions driving the trigger of the action is the user id changing the IC.

We are now looking at using web services to create and change an IC. From reading, a system id needs to be used to communicate with the CRM system. My question is in this case how do we ensure that we can capture the creator id and id that change the IC? Will passing the information into the corresponding fields in the web service work? Has anyone done this before? I want to confirm whether the current action we have will continue to work.

Thanks in advance for any information or experience shared.

Cheers!
