Signed download links from S3zipper are valid for seven days (168 hours) by default. You can change that per job:
expireLink— expiry in hours (for example"expireLink": 24).expireSeconds— the same in seconds, if you prefer.
After expiry the link returns an S3 error; request the result again to obtain a freshly signed URL. The archive itself stays in your bucket until you delete it.
