Google Drive API changes thumbnailLink value on every GET request?

Question

I'm uploading some images to our GDrive account (via API) so I can publish them in our webapp.

I like to post thumbnailLink because of the =s parameter where you can scale the image to a desire width.

But now I've found a problem:

• everytime I make a file get request (https://developers.google.com/drive/v2/reference/files/get) the thumbnailLink changes its value

This problem raises two questions:

1. Why does this happen?

2. Is there anyway I can keep the same thumbnailLink and make it work forever?

edition: in file documentation (https://developers.google.com/drive/v2/reference/files) says that only downloadUrl has a short lived value

Answer 1

The thumbnail URL is also short lived (as some simple testing revealed). I'll work with the documentation team to also have this noted in the documentation.
