How to Manage Your Zapier Custom Actions

Using Zapier with custom actions lets you precisely control how your apps and APIs connect, but you also need to manage those actions over time. This guide explains how to view, edit, test, share, and delete your existing custom actions so your workflows stay accurate and secure.

The steps below are based on Zapier's own documentation for managing custom actions created with the AI-powered Zap editor.

Overview of Custom Actions in Zapier

A custom action in Zapier is a reusable request to an app or API that you configure once and then use across multiple Zaps. You can:

• Store API endpoints with specific methods and authentication.
• Define input fields and map them to request data.
• Reuse the same configuration in different workflows.

Managing these custom actions correctly helps you avoid duplicate work, reduce errors, and keep sensitive data safe.

Where to Find Custom Actions in Zapier

You manage existing custom actions directly from the Zap editor. Once you add or open a step that uses a custom action, you can access its configuration.

1. Open your Zap in the editor.
2. Select the action step that uses a custom action.
3. Look for the custom action settings within that step.

From there, you can open the interface to review and update your configuration.

Edit an Existing Zapier Custom Action

If an API endpoint, field, or parameter changes, you can edit your existing custom action instead of creating a new one. This keeps your Zapier workflows consistent.

Steps to Edit a Custom Action in Zapier

1. In the Zap editor, open the step that uses your custom action.
2. Click to open the custom action configuration panel.
3. Update any of the following as needed:
   • Request URL or HTTP method.
   • Headers or query parameters.
   • Request body or field mappings.
   • Field labels, descriptions, or types.
4. Save your changes.
5. Retest the action to confirm it still works as expected.

When you edit a custom action, changes can affect all Zaps that use that action. Review each workflow that relies on it to ensure everything continues to run smoothly.

View and Test Zapier Custom Actions

Regular testing helps you confirm that your custom actions still behave as expected, especially after API changes.

How to Test a Custom Action in Zapier

1. Open your Zap in the editor.
2. Select the step with the custom action you want to test.
3. Ensure all required input fields have sample data.
4. Click the test button for that step.
5. Review the output returned by the app or API.

If the test fails, verify your authentication, endpoint URL, and request structure. Adjust your custom action, then test again.

Rename or Document Zapier Custom Actions

Clear naming and documentation help you and your teammates understand what each custom action does.

Best Practices for Naming in Zapier

• Use descriptive names that state the purpose, such as "Send Lead to CRM API".
• Include the app or API and the main operation in the name.
• Keep names short but specific so they are easy to recognize in the Zap editor.

Documenting Custom Actions

Inside the configuration, use descriptions or notes to capture:

• Required fields and expected data formats.
• Any authentication or header requirements.
• References to related API documentation.

Good documentation reduces confusion and makes it easier to troubleshoot Zapier workflows later.

Share Zapier Custom Actions With Your Team

If you work in a team or company account, you may be able to share custom actions so others can reuse them in their own Zaps.

Sharing Considerations in Zapier

• Confirm whether your account or workspace supports shared resources.
• Ensure shared custom actions do not contain hard-coded secrets or personal data.
• Provide clear naming and descriptions so teammates understand how to use them.

Shared custom actions can help standardize how your organization interacts with an API across multiple workflows.

Delete a Zapier Custom Action

Removing old or unused custom actions helps keep your Zapier environment organized and reduces the risk of using outdated configurations.

When to Delete a Custom Action

• The API endpoint is permanently deprecated.
• You replaced it with a newer, more reliable configuration.
• The custom action is no longer used in any active Zap.

How to Delete Zapier Custom Actions

1. Open the Zap or Zaps that rely on the custom action and confirm they no longer need it.
2. Locate the custom action in the relevant step.
3. Remove the step or change it to a different action if necessary.
4. Use the delete option for the custom action if available in your interface.

Before deleting, take note of any configuration details you may want to reference later, such as field mappings or endpoint URLs.

Security Tips for Custom Actions in Zapier

Because custom actions often send data to external services, manage them carefully to protect sensitive information.

• Avoid hard-coding secrets, tokens, or passwords in URLs or request bodies.
• Use secure authentication methods supported by the app or API.
• Test with non-sensitive sample data whenever possible.
• Review who has access to shared custom actions in your workspace.

Regularly audit your Zapier custom actions to remove unused or risky configurations.

Troubleshooting Zapier Custom Action Issues

When a custom action fails, the error messages from the connected service can guide you to the cause.

Common Issues

• Authentication errors due to expired or invalid credentials.
• 404 or 500 errors from incorrect endpoints or server issues.
• Validation errors caused by missing or invalid fields.
• Rate limit errors when too many requests are sent.

How to Resolve Problems

1. Check the error message and status code in the test output.
2. Compare your configuration with the API's official documentation.
3. Confirm that field mappings and data types match what the API expects.
4. Update and retest the custom action until it returns the desired result.
