Thanks for the question, @wangdao1.

The POST accounts/:account_id/account_media endpoint only accepts newly uploaded images. That is, right after the POST media/upload step.

If you’re curious about what “newly uploaded” means, it’s essentially before the image expires. In the upload response, there’s an expires_after_secs field:

{
  "media_id": 1037471778908426240,
  "media_id_string": "1037471778908426240",
  "size": 1110205,
  "expires_after_secs": 86400,
  "image": {
    "image_type": "image/jpeg",
    "w": 300,
    "h": 250
  }
}

After this point, it will not be possible to add this image as an account_media entity.

Hope this helps. Thanks!
