Hey - The collection needs to be published in Webflow for the API to work. Even if you've created the collection and fields, you'll need to publish those changes.
Without publishing, the API endpoints won't be accessible. To find your Webflow collection ID:
1. Go to Webflow Designer > Pages > CMS Collections
2. Click on your collection name
3. The ID will be in the URL - it's the string after /collection/
The format looks like: webflow.com/design/site-name/collection/COLLECTION-ID
Make sure the fields in your Clay table match exactly with your Webflow CMS field names to avoid the "failed to parse body input" error. The JSON structure needs to align perfectly between both systems.
In any case, I would recommend using ChatGPT or Claude to help you go through this since it can be quite complicated. They should be very helpful! :)
