Using custom actions Limitations

Custom Actions allow you to create your own actions for existing public apps on Zapier with the help of AI. By using the app's public API, you can create actions that are not available by default using HTTP requests.

Beta

Custom Actions are a beta feature. It is available for use, but is still in active development and may change.

Note

To use this feature, you must be familiar with sending HTTP requests, using APIs, and reading API documentation.
Our Support team is able to provide basic troubleshooting for this feature, but they cannot troubleshoot the API you use.

Using custom actions

With Custom Actions, you can:

Create custom actions when an existing app on Zapier does not have the actions you need.
Use your personal and shared app connection accounts to automatically set the authentication header.
Share and reuse custom-made actions across Zaps and teammates.
View comprehensive API responses.

To create your action, you'll use Copilot, an AI-powered chatbot, to generate your action settings, streamlining the process of creating an action. Copilot eliminates the need to manually search for the method and API endpoint in an app’s API docs and auto-fills the action settings. You can also use a code editor to further refine your action using Typescript.

Zapier recommends using Custom Actions when creating a specific action to use in more than one Zap. Custom Actions are an excellent way to share your custom actions with your teammates.
