Hey Keith
Your answer might be here: Problem with Webflow Zapier Integration - #6 by tim28
After trying to fight against the system, I simply discovered that I forgot to update my multi-ref IDs in my database… You need to update these webflow IDs in Airtable/Sheets so that Zapier picks up the right IDs when firing the webhook. So simple but so easily overlooked. I was literally just banging wrong IDs onto the CMS door…Hope this helps you too!
PS: I had the issue after “mistakenly” backing up my site from a previous save (big mistake, don’t do it). It changes all of your item IDs…ALL OF THEM.
