Webflow API Basics

The Webflow API is a REST API that uses standard HTTP methods to perform operations on Webflow resources. The API follows RESTful principles, making it intuitive for developers familiar with modern web development practices.

API Architecture

The API is built around these core components:

• Base URL: All API requests start with https://api.webflow.com
• API Version: Currently at v2 for most endpoints
• Request Format: JSON for request bodies
• Response Format: JSON responses with appropriate HTTP status codes

Rate Limits

Webflow enforces rate limits to ensure platform stability:

• Free plans: 60 requests per minute
• Site plans: 120 requests per minute
• Workspace plans: 180 requests per minute

Exceeding these limits results in 429 (Too Many Requests) responses. Implementing proper request throttling and error handling is essential for production applications.

Authentication

Before making API requests, you need to authenticate with the Webflow API. The platform supports two primary authentication methods.

API Tokens

For server-side applications and scripts, API tokens provide a straightforward authentication method:

• Log in to your Webflow account
• Navigate to Account Settings > Integrations
• Generate a new API token with appropriate scopes

Once created, include the token in your API requests using the Authorization header:

Authorization: Bearer YOUR_API_TOKEN

API tokens should be kept secure and never exposed in client-side code.

OAuth 2.0

For applications that need to access Webflow on behalf of users, OAuth 2.0 provides a secure authorization flow:

• Register your application in the Webflow Developer Portal
• Implement the OAuth 2.0 authorization code flow
• Request specific scopes based on your application's needs
• Exchange the authorization code for an access token

The OAuth flow is ideal for third-party integrations and applications that need to access multiple user accounts.

Key API Endpoints

The Webflow API offers a comprehensive set of endpoints for interacting with different aspects of your Webflow sites.

Sites Endpoint

The /sites endpoint allows you to retrieve information about sites you have access to:

GET https://api.webflow.com/sites

This endpoint returns a list of sites with their IDs, names, and other metadata. The site ID is a crucial parameter needed for most other API operations.

Collections Endpoint

To interact with Webflow CMS collections:

GET https://api.webflow.com/sites/{site_id}/collections

This endpoint returns all collections for a specific site, including their schemas and configuration.

Items Endpoint

To work with collection items (content):

GET https://api.webflow.com/collections/{collection_id}/items

This endpoint allows you to retrieve, create, update, and delete items within a collection.

Webhooks Endpoint

To set up event notifications:

POST https://api.webflow.com/sites/{site_id}/webhooks

Webhooks allow your application to receive notifications when specific events occur in Webflow, such as when collection items are created or updated.

CMS Operations

The Webflow API's CMS capabilities are particularly useful for content automation and integration scenarios.

Reading CMS Items

To retrieve items from a collection:

GET https://api.webflow.com/collections/{collection_id}/items

This request supports several query parameters for filtering and pagination:

• limit: Number of items to return (default: 100, max: 100)
• offset: Number of items to skip
• sort: Field to sort by
• filter: Filter items based on field values

Creating CMS Items

To add new items to a collection:

POST https://api.webflow.com/collections/{collection_id}/items

The request body should include fields that match the collection's schema:

{
  "fields": {
    "name": "New Product",
    "slug": "new-product",
    "description": "Product description",
    "price": 99.99
  }
}

Updating CMS Items

To modify existing items:

PATCH https://api.webflow.com/collections/{collection_id}/items/{item_id}

Include only the fields you want to update in the request body.

Publishing CMS Items

Created or updated items are not automatically published. To publish items:

PUT https://api.webflow.com/collections/{collection_id}/items/publish

Include an array of item IDs in the request body to specify which items to publish.

API Limitations

While powerful, the Webflow API has certain limitations developers should be aware of.

Design and Layout Limitations

The API primarily focuses on content management rather than design:

• Cannot create or modify design elements (layout, styles, interactions)
• No direct access to the Designer API used by Webflow's visual editor
• Cannot create or modify custom code components

For design changes, you'll still need to use Webflow's visual editor.

E-commerce Limitations

The API offers limited e-commerce capabilities:

• Can read product information but cannot create or update products directly
• Limited order management capabilities
• No direct access to payment processing or cart functionality

For advanced e-commerce needs, consider migrating from Webflow to Shopify or using specialized e-commerce APIs alongside Webflow.

Performance Considerations

Working within API constraints requires thoughtful planning:

• Rate limits restrict high-volume operations
• Bulk operations need to be carefully managed
• Publishing delays can impact time-sensitive content updates

Using our Website Optimizer can help identify if API integrations are affecting your site's overall performance.
