For us to make the Facebook app for you, we need a temporary Admin Access to process the integration. Please follow the steps below:
1. Open your store's Facebook page and on the upper right hand corner click the "Settings" button.
2. Next, click on "Page Roles".
3. Then add the email address firstname.lastname@example.org then select "Admin" on the roles and click "Add". Normally, you will be asked to input your account password for security verification, please do so to proceed.
As soon as we are added as an Admin into the account, we will be able to create the app and integrate it into your Facebook page. Please also note that the Facebook app integration is ONLY available on web browsers and is currently not supported by Facebook mobile apps due to Facebook's app canvas restrictions.
After the integration is complete, the Online Order app will be available on your Facebook page as shown below:
Then your Online Order menu inventory will be ready to take online orders from your Facebook page.
