Hello! I need help!
Each time I try to create a Live Item using Zapier I get the following error message…
"The app returned "User is not authorized to perform this action: Cannot complete operation for the ecommerce collection [Products] with this endpoint.".
How do I fix this? What am I missing?

Welcome to the forums @zachjarrr,
I believe you need to use the Webflow ecommerce API to create products. The CMS API can be used to update some fields on products, but it’s deceiving because ecommerce products are more complicated than normal CMS collections.
Wish I could help more, but I don’t have much experience with the ecommerce API. 
Following - Just experienced the same thing. Looking how to fix this as Zapier is showing the ability to update Ecom collections
Could you show us what you’re doing in Zapier that triggers this? Screenshots would be helpful…
