You must have a Facebook page that you manage and have the ISN online scheduler already turned on and set up under Settings---Office Settings -- Online Scheduler Version # Settings to use this feature.
Next, go to the Website Integration options, and copy the Direct URL:
Then, navigate to your Facebook page and click the Add Button button in the upper right corner of the page.
Click on Start Order:
Paste the URL for your scheduler in and hit 'Save!'
From there, you're all set!
You can test it by hitting Edit Start Order --> Test Button and it will jump you right into your online scheduler!
Please note: Facebook no longer supports our legacy facebook scheduler. This is the only method we recommend at this time.
