We strongly recommend using only paginated ListBuckets requests. Unpaginated
ListBuckets requests are only supported for Amazon Web Services accounts set
to the default general purpose bucket quota of 10,000. If you have an approved general
purpose bucket quota above 10,000, you must send paginated ListBuckets requests
to list your account’s buckets. All unpaginated ListBuckets requests will be
rejected for Amazon Web Services accounts with a general purpose bucket quota greater
than 10,000.
You must URL encode any signed header values that contain spaces. For example, if
