Hello everyone, I saw couple of people here in the community asking about this matter. I couldn’t reply to their topics since it is closed so I decided to put the solution here in a convo.
After searching online, I couldn't find an answer. Many said it was impossible to upload multiple images to Webflow CMS using Zapier. But guess what? 
I figured it out, and now I'm sharing the recipe with you! 
I used Uploadcare, JavaScript, Webflow CMS and Zapier Custom Webhooks.
I'd love to hear your thoughts
and I am curious if someone found another solution!
