Facebook

To be able to post on Facebook and Instagram, you must create and configure a Facebook application. Because Facebook and Instagram belong to the same company Meta.

Step 1: Create a Developer Account

To create a Facebook app, you must first have a Facebook developer account. If you don't already have one, go to the Facebook for Developers website and click "Get Started" in the top right corner. Follow the instructions to sign up for a developer account.

Step 2: Create a New App

Once you have a developer account, go to the Facebook Developer Dashboard and click "Create App" in the top right corner. Choose "Business" as the app type and give your app a name.

Step 3: Configure Basic Settings

After creating your app, you'll be taken to the app dashboard. Here, you can configure your app's basic settings, such as the app icon and description. You'll also need to configure the "App Domains" and "Privacy Policy URL" settings.

Next, on this page, scroll down to the “Add Platform” button and click it.

Enter your application URL. We recommend that you enter a secure URL to avoid certain problems when connecting to Mixpost.

Step 4: Copy the App ID and App Secret to Mixpost

After creating the App, you will see the App ID and hidden App Secret. Copy them, open your Mixpost dashboard, and paste the keys to Facebook third-party service form.

Mixpost Lite: From the left sidebar->Services.
Mixpost Pro/Enterprise: User Menu->Admin Console->Services

Select the version of your Facebook application: Your Facebook app->Settings->Advanced

Step 5: Setting callback links

Next, you need to do some essential configurations.

On the left sidebar, click on “Add product” and select “Facebook Login” or “Facebook Login for Business.”
If you selected “Facebook Login for Business”, you need to Switch to the standard “Facebook Login”.
Go to the “Valid OAuth Redirect URIs” input and enter these callback URLs:
- https://your-app-url.com/mixpost/callback/facebook_page
- https://your-app-url.com/mixpost/callback/facebook_group
- https://your-app-url.com/mixpost/callback/instagram (For Mixpost Pro version supports Instagram)
Click “Save changes”

Step 6: Testing

You can test your app by adding your Facebook account to the Mixpost.

Conclusion

Your Facebook app can only request data from users with an app role. For users who do not have a role in the application, your Facebook app must have Advanced Access permissions.

App Review (Advanced Access permissions)

If your app is used by app users who do not have a role on your app or a role in a Business that has claimed your app, you must switch App Mode to Live and request approval for advanced access permissions via App Review. This step is recommended for those who have Mixpost Enterprise.

Note that Business Verification is required to gain advanced access.

Navigate to "App Review > Permissions and Features"

If your Facebook App is using v17.0, you must request permissions for the following scopes:

business_management
pages_show_list
read_insights
pages_manage_posts
publish_to_groups
instagram_basic
instagram_content_publish
instagram_manage_insights

If your Facebook App is using v16.0, you must request permissions for the following scopes:

pages_show_list
read_insights
pages_manage_posts
publish_to_groups
instagram_basic
instagram_content_publish
instagram_manage_insights

Before submitting the app for review, it is essential to finish all the required steps and provide information for each requested permission. The "Submit for Review" button located at the bottom of the page will become active only when all the review requirements, indicated by blue checkmarks, are fulfilled.

It can take several days to get a response from Facebook. You can check your pending request in the Facebook developer account in the "App Review -> Requests" section.
