Is it possible to create an integration/plugin for Webflow that enables bulk upload of image assets from Figma/Sketch/Adobe? Can you please provide information on how to gain API access and the relevant technical documentation for this?

TL;DR
  • Export images from Figma, Sketch, or Adobe XD using their APIs or plugins.
  • Upload images to an external host (e.g., AWS S3, Cloudinary).
  • Use the Webflow CMS API to insert image URLs into CMS items (direct upload to Webflow Asset Manager is not supported).
  • Authenticate via Webflow API using a personal token or OAuth and follow their CMS API docs for integration.

Yes, it’s possible to build an integration that enables bulk upload of image assets into Webflow from design tools like Figma, Sketch, or Adobe XD—using the Webflow API. However, there are some key limitations and considerations around asset uploads and API capabilities.

1. Understand Webflow API Limitations

  • The Webflow CMS API allows you to create and update CMS items, including image fields via image URLs—not direct file uploads.
  • Uploading to Webflow’s Asset Manager (the Designer-level Assets panel) is not currently possible through the public API. Webflow doesn't support uploading raw assets outside of CMS image fields via API at this time.
  • You can work around this by uploading your image assets to an external image host and referencing those URLs when creating CMS items.

2. Use Cases You Can Support

  • Figma/Sketch/Adobe XD → Upload to Cloud → Generate URLs → Send to Webflow CMS.
  • If you're exporting assets (e.g., JPEGs/PNGs) from design tools, you can:
  • Export via the respective APIs (Figma has a solid API; Sketch is more limited; Adobe XD requires plugins).
  • Upload images to a host like AWS S3, Cloudinary, or Firebase.
  • Use the Webflow CMS API to insert image URLs into image fields on CMS items.

3. How to Gain Webflow API Access

  • Go to Webflow Developer Portal.
  • Read the Webflow REST API documentation for authentication scopes, endpoints, and usage.
  • You need:
  • A Webflow account with Workspace-level Admin access (to link APIs to sites).
  • To register a custom application (if deploying OAuth scopes for external integrations).
  • To use a Personal API Token or OAuth client depending on your integration model.

5. Workflow Overview for Integration

  • Export Assets from Design Tool:
  • Use Figma’s ‘Export Output’ via API, or plugin hooks in Sketch/XD.
  • Upload Assets to a Public Host:
  • Services like AWS S3, Google Cloud Storage, or image-specific CDNs like Cloudinary are common.
  • Use Webflow CMS API:
  • Authenticate using a personal API key or OAuth2.
  • Use the /collections/:collection_id/items POST method to add items with image field URLs.

Summary

You can create a plugin or integration to bulk upload image assets to Webflow CMS image fields by exporting from Figma/Sketch/Adobe, hosting the images externally, and then using the Webflow CMS API to point to those images. Direct uploading to the Asset Manager is not supported. Use the Webflow API documentation to authenticate and interact with CMS content.
