# Facebook (Meta)

> How to create OAuth credentials for Facebook (Meta).

Facebook uses OAuth 2.0 via the Meta for Developers platform. The same process applies to other Meta apps (WhatsApp, Instagram). You need a developer account linked to a business portfolio.

## Steps

1. **Create a Facebook Developer Account**
   * Go to [https://developers.facebook.com](https://developers.facebook.com)
   * Create a developer account (requires a Facebook account)
   * Link it to a [business portfolio](https://developers.facebook.com/apps/creation/)

2. **Create an Application**
   * In the top-right corner, click **Create App**
   * Enter basic app details
   * Select relevant **use cases** based on your workflow
   * Select your business on the business tab
   * Fill in remaining details and create the app

3. **Get Client ID (App ID) and Client Secret (App Secret)**
   * Navigate to your application
   * Go to **App Settings → Basic**
   * Find the **App ID** (Client ID) and **App Secret** (Client Secret)
   * Copy both values

4. **Configure the Redirect URI**
   * In **App Settings → Advanced**
   * Add your OAuth callback URL to the **redirect allow list**

5. **Publish the Application**
   * Configure any additional settings needed
   * Publish the application to make it live
