Moving tickets to other workspaces and the visibility for the previous agent

Hi Yooji,

Maybe the below solution can help.

1, Create a custom dropdown field, for example: Event performing user and make it as a data source with agents.

 

2, Create a workflow automator with the below configuration.

Event:

 

Web request (Node 2):
 

You can find the API field name for the custom field using this API call - Service Desk API for Developers | Freshservice
You can find the placeholders for event performing agent ID in the “insert placeholder” option - above the body field.
 

I would suggest using “?bypass_mandatory=true” at the end of the endpoint URL which will help execute the API call without any errors like missing a mandatory field.

3, Action:

I am using the placeholder of the custom field (which currently holds the agent's name who updated the workspace field) as the watcher value.
