Official docs: https://developers.webflow.com/data/reference/rest-introduction

When to Use

Use this skill when you need to:

List and inspect sites in a Webflow workspace
Read page metadata and site structure
Manage CMS collections — list, create, delete collections and fields
CRUD CMS items — create, read, update, delete, and publish collection items
List and manage assets (images, files) on a site
Retrieve form submissions from Webflow forms

Prerequisites

Connect your Webflow account via the vm0 platform (OAuth connector). The WEBFLOW_TOKEN environment variable is automatically configured.

Verify authentication:

curl -s "https://api.webflow.com/v2/token/authorized_by" --header "Authorization: Bearer $(printenv WEBFLOW_TOKEN)" | jq '{id, email, firstName, lastName}'

Expected response: Your user information (id, email, name).

How to Use

All examples assume WEBFLOW_TOKEN is set.

2. List Sites

curl -s "https://api.webflow.com/v2/sites" --header "Authorization: Bearer $(printenv WEBFLOW_TOKEN)" | jq '.sites[] | {id, displayName, shortName, lastPublished}'

3. Get Site Details

Retrieve details for a specific site. Replace <site-id> with an actual site ID from the list sites response.

Guidelines

Start with /v2/token/authorized_by: Always verify auth first before calling other endpoints
Get site ID first: Most operations require a site ID — call List Sites first
CMS workflow: List collections -> get collection schema -> CRUD items -> publish items
Staged vs Live items: By default, item endpoints work with staged (draft) items. Use /items/live path for published items
Pagination: List endpoints support offset and limit query parameters (default limit is 100)
Rate limits: 60 requests per minute; back off on 429 responses
Field data: When creating/updating items, field values go inside the fieldData object, keyed by field slug
