S3 file URL expiration limit

The links of files uploaded to S3 look have the expiration limit. Is that 30 mins? How do you confirm that?

If using an external S3, the expiration limit is configurable from the second to 7 days.

do you know how to setup that in detail?

Yes.

You may use the “Get Download Presigned Expiring URL” action with a configurable expiration time. You will find detailed instructions on this plugin page:

Please note that it only applies to external AWS S3, not Bubble’s storage.
