We’ve updated the official Unsplash API Guidelines to include two new technical guidelines for all API applications:

  • All API uses must use the hotlinked image URLs returned by the API under the photo.urls properties. More info & examples →
  • When your application performs something similar to a download (like when a user chooses the image to include in a blog post, set as a wallpaper, etc.), you must send a request to the download endpoint returned under the photo.links.download_location property. More info & examples →
