Impossible to call the balance history API from the SDK

[jfougere]

It seems that the API spec on which the SDK is built is not aligned with the real API implementation as we can see here:

Even though the contact_id and balance_definition_id were provided the API responds with "contact_id is a required field".

The spec and the SDK are using contact_id and balance_definition_id but the API is actually expecting those mandatory parameters in camel case.

Could you please fix the API spec and the SDK so that we can use the SDK to call this API ?
