Zapier is a great tool, but it’s not meant to handle multi-reference fields. I’d recommend trying something like PowerImporter, which will take care of all your reference fields (and more) for you.
Hi Bilal, not sure if you found a solution here already, but one option to consider is Whalesync’s Airtable x Webflow sync. It handles multi-reference fields out of the box.
We actually started the company because we saw so many so people struggling with hooking up Airtable to Webflow with Zapier (with multi-ref in particular being a huge headache).
