Project name change

Project name change

Can somebody help me with the simple logic? 

I would like to keep Zoho Project names in sync in another service.
Flow1: Trigger: Project created, custom function to send id and name
Flow2: Trigger: Project updated.

how do I know what was changed? Would be nice to have 2 variables: old state, new state.
I need only name changes, otherwise flow will run on all (unnecessary) updates.
