Returns the details relating your account, including your discount rate and Betfair point balance.
Please note: The data returned by getAccountDetails relies on two underlying services. The pointsBalance is returned by a separate service from the other data.
As a consequence of this, in the event of a failure to a single underlying service, either the pointsBalance or the remaining data may not be included in the getAccountDetails response. If both services fail, the error UNEXPECTED_ERROR will be returned.
