+### Error Handling
+Error handling has been added in version 2.0. Currently, the only HTTP error codes that
+are handled are the ones documented on the GDAX API error section: [here](https://docs.gdax.com/?python#errors)
+
+HTTP STATUS CODE 400: Raises InvalidGdaxRequest
+HTTP STATUS CODE 401: Raises UnauthorizedGdaxRequest
+HTTP STATUS CODE 403: Raises ForbiddenGdaxRequest
+HTTP STATUS CODE 404: Raises NotFoundGdaxRequest
+HTTP STATUS CODE 4XX: Raises UnknownGDAXClientRequest
+HTTP STATUS CODE 5XX: Raises InternalErrorGdaxRequest
+
+All HTTP requests from both the public client and authenticated client run through `_determine_response`, which
+either returns the JSON body or raises the appropriate error.
+
+Please consider creating new Exception classes and mapping as Gdax error states are discovered.
+
+
