Zapier's Paths feature handles conditional logic and it is what I use when a single-action Zap is not enough
Most people who use Zapier casually know Zaps as linear. Something happens, something else happens. That covers a lot of automation use cases. When you need an automation to do different things depending on what the data looks like, that is where the Paths feature comes in and it is worth writing about specifically.
Paths let you build conditional branches into a Zap. Depending on what value a field contains, the automation takes a different route. A new form submission from an enterprise account goes one way, from an SMB account goes another, from an existing customer goes a third way. A support ticket marked urgent gets routed differently from a standard inquiry. An order above a certain value triggers additional steps that smaller orders do not.
That conditional logic is the difference between automating a simple action and automating a decision-making process. Once I understood Paths properly I rebuilt several automations that had been doing approximate work into automations that were doing precise work.
The Zapier Tables for storing data that automations can read from and write to handles the cases where you need to maintain state between Zap runs rather than just passing data through.
The Real-Time Monitoring and Error Handling shows every execution and what happened at each step. For a Zap with Paths where something is going to the wrong branch, the execution log shows you exactly where it diverted and what value caused it.
Zapier Central for the more autonomous AI agent tasks sits on top of all this as the newer addition to the platform.
