Get notified when object in third party S3 bucket gets updated

I need to monitor a file on a third party public s3 bucket and would like to get notified when the file gets updated(replaced). Please note that the third party is not going to implement a Lambda trigger for me so S3 Lambda event triggers etc won't help. Any solution other than polling?

Like i said the bucket is a third party bucket who is unlikely to make any modifications on their part to deliver created object events to a lambda or queue.

If the bucket owner is unwilling to do anything (eg configure Amazon S3 Events), then there is no way to be automatically notified when an object is added/updated.

This is good — would you want other people to be able to monitor your buckets like that? Presumably not.

If the bucket is publicly accessible, you should be able to call HeadObject() on the file at regular intervals to determine whether it has changed. The Create Date and eTag should be sufficient to detect a change.
