# Validation on embed block URLs

The public API will now return errors on embeds blocks that are not supported by the public API. The supported embed block types (as listed and kept up to date in the [Block Object](/reference/block#embed-blocks) documentation): 
* Framer
* Twitter (tweets)
* Google Drive documents
* Gist
* Figma
* Invision,
* Loom
* Typeform
* Codepen
* PDFs
* Google Maps
* Whimisical
* Miro
* Abstract
* Excalidraw
* Sketch
* Replit 

Previously failed embeds would return a successful request, but produce an error in the Notion Application. Failed embed requests will now return a 400 Client Error. 

For non embed URLs, consider using the `bookmark` or `image` block types.
