I just wanted to share this because I was using Zapier and was super frustrated. I have started using Built.io Flow Enterprise and it way more powerful than Zapier. link
It’s a little more complicated than Zapier, but it’s well worth learning. You can do so much more with Flow.
I added a wishlist item to request a Flow integration for Webflow.

Very interesting thanks for sharing, could you give a couple of examples of what you’ve achieved with it, on the “Explain it like I’m 5” mode? 
Form Handler - I integrated Webflow sites to a flow with a webhook. I look for headers with the switch element to make logic decisions about where to send the form data. Some forms go to a CRM, some go to a spreadsheet, some get emailed, etc.
CMS updates - I set a daily flow to update Webflow CMS items. It’s easier than Zapier because you can set up loops.
Lead Manager - I’m currently working on a lead routing system to send texts and emails based on time and then save the data to a database.
Blog Updates - I get Buffer entries and send them to update Webflow blog entries. Again, using the switch element to route the data.
You will need to use the HTTP Request element under the Utility section to make calls to Webflow API. Another tool I use when integrating API’s is Postman. It’s a great tool to inspect the API calls and see the returned data.
I can share Flows if anyone needs them. Also, I think I will put together and share a Postman collection for Webflow API’s.
I would be interested in that for sure. Thanks
