Using the following, but do not know how to determine what the primary account is when there are multipe accounts associated.

      account_params = GetUserAccountListAndDetails.ParamsObj(self.logger, self.hq_credentials, True)
    accounts = await GetUserAccountListAndDetails.execute(account_params,use_json=True)

    primary_cif = ''
    for account_elem in accounts.json()['Data']['AccountListResponse']['AccountListResponseRecord']:
        if account_elem['HydraProductTypeCode'] == 'D'and account_elem['IsExternalAccount'] == 'false' and account_elem['HydraProductCode'] in ['S']:
            primary_cif = account_elem['Cif']
