Is it possible to create custom fields on a Collection via the API?

hello! I’m working on a script to auto-create collections based on a template, and I’m not sure about one bit: is it possible to create custom fields on a Collection via the API that aren’t already there?

that is, let’s say I have a “Blog Post” collection, and I’d like to add a “Co-Author” field. In the UI, I’d do that by going to Blog Post settings → Collection fields and add it there. However, I don’t see an equivalent API call in the documentation:

https://developers.webflow.com/#collections

There are “List” and “Get” operations, but no PUT, PATCH, etc. for altering fields. Is this not possible to do at present, or am I missing something? thanks!

Hi @hbbtstar :wave: welcome to the forum.

Unfortunately no, you are not missing something, that is not possible.
