It appears that the 'offset' parameter was added, and then inadvertently removed with this update. https://github.com/hyperwallet/php-sdk/commit/a3eec7c56daf34a1f472d84a3ca7887c324a1e99 I believe 'offset' is valid for v3 and should be allowed in 1.x. We continue to have to use a forked repo to pass that to the API.
