While we currently do not support adding a FB pixel to the Waitwhile check-in flow, we have a creative workaround that should be the next best thing.
Want to add it for your business? Here are the steps:
Create a page on your own website where the FB pixel is implemented (Check out this link for an example!)
In the ads, send users to your Waitwhile Booking page URL with our "redirect_url" parameter. I.e. https://app.waitwhile.com/book/cutbarbershop?redirect_url=www.cutbarbershop.com/successful-booking
After the user has completed the booking, they will be redirected over to your page which will fire the FB pixel
Hope that helps!
