# Get Presigned URL

**Get Presigned URL** node helps us to generate a presigned URL that provides temporary access to a specific resource, typically hosted on cosmocloud **object storage buckets**. 

This URL is generated with a limited set of permissions and an expiration time, allowing users or applications to securely access the resource without requiring permanent access credentials.
