Zoho flow for Zoho desk when ticket gets tagged

Zoho flow for Zoho desk when ticket gets tagged

Good afternoon

My company 15d trial for zoho flow has ended as we started it by a mistake without actually using any flows and before I decide to purchase the module for £80, I'd like to know if is it available for Zoho Flow to trigger on ticket update with condition of assigning a tag to the ticket? For an example - a user does read the ticket and decides to set a tag on it. Then I want Zoho flow to move the ticket to a different department and inform a 3rd party company with mail.  

The problem exists because we have dedicated department that deals with samples. And both: customers and some of our sales rep, can send request for samples to either sales or customer services instead directly to samples department. 

Thank you
