Will file URL’s captured by API be affected by the planned November changes to the Attachment field?

Currently I have a Bubble.io app that gets a file’s URL by API. I don’t store a static URL to the files in the attachment field but I do use Bubble’s Get external data from an API feature to get the record’s Attachment URL.

Since this API call is made every time a user loads this specific page in the app, my understanding is that a new URL is captured on every load of the page. This would mean that a new URL good for 2 hours will be captured on every API call. Is this correct?

I am trying to figure out how much this planned change will affect my app but I can’t find any information specific to the use of the Attachment field by API.
