Question about Bolden Academy

On Youtube there is a great video on Bolden Academy and how to send emails but also how to send stuff to WIX. Is this working or is it a bit to early published?

He sends data from IFTTT to a WIX page, I saw this sample on the keynote about WIX as well.

I am referring to the red lines in the screenshot and just wonder, does this work as of today?

Ot the logAttendance function I write about.
