Hi @Jules,

You can share your Calendly link on your Facebook page in the section about your business, in posts (consider a pinned post!), and in replies, but there are currently no native integrations with Facebook.

Thanks Jillian 

If you manage a Facebook business page, consider integrating Calendly with the Meta pixel (previously known as the Facebook pixel) to enhance your understanding of social ad campaigns. This integration allows you to track visits and user actions on your Calendly booking page, offering valuable insights into the effectiveness of your advertising.

and may be you get more better help from here: https://help.calendly.com/hc/en-us/articles/360038353914-Meta-Pixel#meta-pixel-0-0

Thank you
