Build a Zapier integration - design triggers and actions for your product, wire up authentication, then publish to the App Directory.

Bring Zapier’s automation into your own product so customers can build workflows and run actions without leaving your app.

Connect AI assistants to Zapier through MCP so they can call any app action on the platform using natural language.

Use the Zapier SDK to run actions and manage connections from your backend or agents, all in a few lines of code.
