Webflow: posting rules and settings

What a Webflow channel accepts in Postemi: media, limits, required fields, and the fields of the settings object for the API.

Beta

New in Postemi and not yet tested with many sites. Tell us if something does not work.

Basics

Platform

Webflow

Character limit

The platform does not specify a general limit.

Media

The cover is the image setting or the first picture, 4 MB at most (Webflow skips a bigger one). Other pictures follow the text in the body; a video is added as a link.

settings.__type

webflow

Required fields

collection, title

Platform page

Webflow CMS scheduler

Rules

You connect with a Site API token (Site settings > Apps & integrations > API access; Sites: read, CMS: read and write). One token connects one site.
The post becomes a CMS item in the chosen collection: the title is its name, the text goes into a Rich text field, the cover into an Image field, a short summary into a summary or excerpt field when the collection has one.
A collection with other required fields is refused before anything is written. Make those fields optional in Webflow, or choose another collection.
With status "published" the item goes live at the scheduled time; with "draft" it is saved as a staged draft.
Beta: not yet tested with many sites.

Settings fields

These fields go into the post's settings object, alongside the __type field. In the UI, you fill in the same ones in the channel's settings section.

Field	Type	Required	What it does
collection	string (id)	yes	The collection to post to (the collections function lists them).
title	string	yes	The item name, up to 256 characters.
slug	string	no	a-z, 0-9 and dashes. Empty: made from the title.
status	"published" \| "draft"	no	Defaults to "published".
bodyField	string	no	Slug of the Rich text field for the text (the fields function lists them, with { id } of the collection). Empty: post-body, body or content, else the first Rich text field.
imageField	string	no	Slug of the Image field for the cover. Empty: main-image, thumbnail or a similar field, else the first Image field.
summaryField	string	no	Slug of a Plain text field for the summary. Empty: post-summary, summary or excerpt when the collection has one.
summary	string	no	Up to 250 characters. Empty: the start of the post.
image	{ id: string; path: string }	no	The cover image. Empty: the first picture of the post.

Examples

Each example is one item in the POST /public/v1/posts request's posts array. The envelope around it is always this:

{
  "type": "schedule",
  "date": "2026-09-15T09:00:00.000Z",
  "shortLink": false,
  "posts": [ /* the item below */ ]
}

{
  "integration": { "id": "<channel-id>" },
  "value": [{ "content": "<p>The text of the post.</p>", "image": [] }],
  "settings": { "__type": "webflow" }
}

The channel ID comes from the channel list, and the path values for images and videos from media upload. The exact schema for the connected account comes from the settings schema endpoint. From the command line, the same thing is the --settings flag. See the CLI examples.
