Zapier deprecates Zapier Functions, shutdown September 1

What changed

Zapier deprecated Zapier Functions. Zapier says existing functions continue to run until September 1, 2026 and that all functions stop running after that date. The change affects anyone who built workflows on Zapier Functions. Zapier tells users to migrate to Code by Zapier.

Event dates

The Zapier Help Center article carries the stamp "Updated May 29, 2026". It gives June 1, 2026 as the date after which you cannot sign up or create new functions, and September 1, 2026 as the shutdown date.

Details as the source states them

• Zapier Functions no longer accepts new users. You cannot sign up for Functions or create new functions after June 1, 2026.
• Existing functions continue to run until September 1, 2026. After that date, all functions stop running.
• Zapier says: "Your code is preserved. No code will be deleted in 2026."
• Zapier says it is consolidating its code capabilities into Code by Zapier, which runs natively inside Zaps and supports JavaScript and Python.
• Zapier lists these Code by Zapier capabilities: npm and PyPI packages, AI-assisted code generation, and the Zapier SDK (JavaScript only).
• Zapier says that after September 1, 2026 "Deployed functions will no longer execute, and the Functions interface will no longer be accessible."
• The recommended steps are: review the migration guide, copy your function code from the Functions home, rebuild the workflows in Code by Zapier, then test and publish the updated Zaps.

What this does not say

• The article does not say what happens to your code after 2026.
• It does not list a price for Code by Zapier or say which plans include it.
• The migration guide is a separate page that this news item does not cover.

What to check

As of 2026-10-03, the September 1, 2026 date stated by Zapier has passed. If you used Zapier Functions, confirm that each affected workflow was rebuilt and that it runs. Check the Code by Zapier limits on your plan before you rely on it.
