Zapier Custom Actions rename guide
Zapier has renamed the feature previously called App Extensions to Custom Actions. This guide explains what that change means for your account, how it affects existing workflows, and what you should do to keep your automations running smoothly.
What changed in Zapier Custom Actions
The Zapier feature once known as App Extensions now appears everywhere in the product as Custom Actions. Only the name and labels have changed; the underlying functionality remains the same.
- The feature name in the editor, sidebar, and menus is now Custom Actions.
- Any references to App Extensions in the interface were replaced with Custom Actions.
- Your existing configurations, inputs, and outputs keep working as before.
This change is designed to make it clearer that you are building customized actions inside your existing connected apps in Zapier.
How the rename affects your existing Zaps in Zapier
If you used App Extensions before the rename, your existing Zaps in Zapier will continue to function. No new build or migration is required to keep things working.
Here is what stays the same:
- Your Zaps still run on their existing schedules and triggers.
- Previously created extensions are still present and usable as Custom Actions.
- Field mappings, authentication, and data flow are unchanged.
The only visible difference is that any step or configuration previously labeled App Extension is now labeled Custom Action in the Zapier editor and related menus.
Where to find the new Custom Actions in Zapier
To locate what used to be App Extensions, look for Custom Actions in the main Zapier workflow editor and sidebar.
Finding Custom Actions in the Zapier editor
- Open your Zap in the Zapier editor.
- Click on the step where you previously used an App Extension.
- Confirm that the step now shows Custom Action instead of App Extension.
Any new custom steps you create for supported apps will use the Custom Actions label automatically.
Viewing existing Custom Actions in your Zapier account
- Go to your main dashboard in Zapier.
- Open a Zap that relied on App Extensions.
- Review each step for the Custom Action label to confirm replacements.
You do not need to manually re-create any steps. The rename is handled for you automatically within Zapier.
How to work with Custom Actions after the Zapier rename
You can keep building and editing Custom Actions in Zapier just as you worked with App Extensions. The workflows and configuration patterns are identical.
Editing an existing Custom Action in Zapier
- Open the Zap that contains the Custom Action.
- Select the Custom Action step in the editor.
- Adjust input fields, mappings, or options as needed.
- Test the step to verify that it behaves as expected.
- Publish or turn on the Zap to apply your changes.
Every edit you make is saved under the new Custom Actions name, but the behavior matches your previous App Extensions usage.
Creating a new Custom Action in Zapier
- In the Zapier editor, add a new action step.
- Choose the app you want to customize.
- Look for the option that lets you create or use a Custom Action.
- Configure the endpoint, request, and fields based on your app’s requirements.
- Test the Custom Action and complete any remaining step mappings.
The experience is familiar if you have used the older App Extensions interface. Only the title and wording differ inside Zapier.
Troubleshooting after the Zapier rename
Because the change is primarily cosmetic, most users will not experience issues. If something does not look right in Zapier, you can follow a short troubleshooting checklist.
Common issues with Custom Actions in Zapier
- You cannot find the old App Extensions menu because it is now labeled Custom Actions.
- A Zap step name looks unfamiliar even though it is the same configuration.
- Documentation or training materials still reference App Extensions.
In these cases, simply map all old mentions of App Extensions in your own notes or guides to Custom Actions in Zapier.
Steps to verify your Zaps in Zapier
- Open each Zap that used App Extensions.
- Confirm that Custom Actions appear where you expect them.
- Run a test for any critical workflow.
- Check the Zap run history to confirm success.
If the Zap history shows successful runs, you can be confident that the rename has not disrupted your automations in Zapier.
Documentation and support for the Zapier rename
The official announcement and detailed explanation of the rename from App Extensions to Custom Actions is provided by the Zapier help center.
For reference, you can review the original notice here: App Extensions is renamed to Custom Actions. This page confirms that the shift is a terminology update and that your workflows continue as before inside Zapier.
If you rely on written procedures or internal training, update your materials so that teammates know to look for Custom Actions, not App Extensions, when they work in Zapier.
Next steps for optimizing your Zapier workflows

- Identify Zaps with critical Custom Actions and validate their configuration.
