Will the application that pulls data from Webflow CMS and is used in a React application be publicly listed by Webflow if we have to register it?

If you're building a private application that pulls data from Webflow CMS into a React app via the API, it does not have to be publicly listed on the Webflow App Marketplace.

1. Webflow App Registration Overview

• Public apps must go through Webflow’s App Review process to be listed in the Webflow App Marketplace.
• Private apps (such as internal tools or integrations not meant for distribution) do not require listing and can operate without approval or visibility from Webflow.

2. When You Need to Register with Webflow

• You’ll only need to register your app with Webflow if you're using OAuth authentication to access user data across accounts.
• Registration generates an App ID and App Secret, which lets your users authorize your app securely through Webflow’s OAuth flow.

3. Private Integration Best Practices

• If the React app is for internal use (e.g., within your company or a client project), you can generate a Webflow API token from the Project Settings > Integrations tab and use that without any app registration.
• This token gives you access to that specific project’s CMS data via the REST API — no need to involve the App Marketplace or OAuth.

4. Visibility of Your App

• If you register the app with OAuth but do not publish it to the marketplace, it remains private and not publicly discoverable.
• Only those who have the authorization URL can connect their site to your app.

Summary

Your React app pulling data from Webflow CMS doesn’t need to be publicly listed. You only register it with Webflow if using OAuth, and even then, it stays private unless you explicitly submit it to the App Marketplace.
