Duplicating a previously created Zap allows you to re-use all of your current connections and configurations, and then make some very subtle, but significant, changes.
To copy a Zap:
1. Head to your Zapier Dashboard.
2. Find your Zap and click on the little down-arrow, revealing a drop-down.
3. Choose Copy from the drop-down.
You'll be able to instantly begin editing the Zap, changing its Trigger, its filter conditions, and even its Action.
