Uploads

An upload object has the following fields:

• id → The upload's unique integer ID.
• mimeType → The MIME type of the upload, e.g. "application/pdf" or "image/jpeg".
• name → The name of the file uploaded by the user.
• original → An object with information about the original file uploaded by the user.
  • height → Height in pixels if the uploaded file is an image or null if it is not.
  • url → URL for downloading the uploaded file.
  • width → Width in pixels if the uploaded file is an image or null if it is not.
• preview → An object with information about the upload's preview image. If the uploaded file is an image with either width or height > 500 pixels, then a scaled-down preview image is generated. If the uploaded file is an image of which both the height and width are ≤ 500 pixels, then the original file is used as a preview image. If the uploaded file is not an image file, then a thumbnail image is used.
  • height → The height in pixels of the preview image; always ≤ 500.
  • url → URL for downloading the preview image.
  • width → The width in pixels of the preview image; always ≤ 500.
