I am trying to use Webflow API to create products for e-commerce feature.
POST
https://api.webflow.com/sites/{site_id}/products
But I can not find the {site_id} anywhere.
Here is my site Read-Only: LINK
(how to share your site Read-Only link)
You can get it by doing a GET on sites on the API.
That will list the sites your access token has access to.
The Site ID is also at the top of the HTML in your published site.
