Hi @MiguelDiaz1988

Thanks for the PR! Unfortunately, while this is the needed change, because this codebase is autogenerated, we'll actually need an associated fix in https://github.com/twilio/twilio-oai-generator and ensures the parameter name is cased properly each time this helper library is regenerated. Until a fix has been made there, I won't be able to merge this PR.
