https://api.sbgenomics.com/v2/storage/volumes///members//permissions
This call overwrites the permissions for a member of a specific volume. The volume is specified as volume_id and consists of the owner and name of a volume (for example rfranklin/my-first-volume).
Note that this overwrites all previously set permissions for the member. Refer to the request to modify a volume member's permissionsto update rather than overwrite permissions.
