Defined in:
lib/price_hubble/client/request/data_sanitization.rb

Overview

We like snake cased attributes here, but the API requires camel cased hash keys, so we take care of it in a generic way here. Furthermore, we perform a deep compaction of the given body hash, to strip nil values and empty hashes from the request. There is no need to send null-data on a round trip.
