Released: 2025-10-30 Version 18.0.0 is a BREAKING CHANGE release that contains several important upgrades and changes. Here is a brief breakdown of the main changes (❗ denotes a breaking change):

​
❗ Node.js 22 Support

Zapier Platform v18 runs on Node.js 22 runtime. This is a breaking change as it may affect compatibility with older Node.js versions and dependencies.

​
❗ Schema Changes

The skipCleanArrayInputData experimental flag has been replaced with cleanInputData. This provides more consistent data cleaning behavior across the platform. This change is breaking only if you’re using skipCleanArrayInputData. See cleanInputData flag documentation for more details on how to configure this behavior.

​
❗ New Throttling Middleware

A new throwForThrottling middleware has been added to prevent afterResponse middleware from suppressing 429 (throttling) responses. This ensures proper handling of rate limiting scenarios. This change is breaking if you want to handle 429 responses in your afterResponse. See v18.x and above: the built-in throwForThrottling middleware for how to handle 429s yourself.

​
New Executable Name zapier-platform

The CLI now includes a new executable name zapier-platform while deprecating the old zapier command. Both will work for now, but zapier-platform is the recommended command going forward.
