1.0.0-rc73
(fix): Fix endpoint header parameters being included in request body instead of HTTP headers.
Header parameters (like Idempotency-Key) are now properly extracted from params and
passed via the headers parameter in Request.new() calls.
(feat): Add normalize_keys utility to accept both snake_case and camelCase parameter keys.
SDK endpoint methods now automatically convert camelCase keys (e.g., refundMethod)
to snake_case (e.g., refund_method) at the start of each method. This allows users
to pass JSON data with camelCase keys directly to SDK methods without manual conversion.
1.0.0-rc72
(chore): Add sdkVersion as a top-level field in the generated metadata.json file.
