Each balance change includes the source information, token ID, changed amount, account balances before and after the change, flow direction, and creation time. You need to specify `source_account`. Currently, use `developer` as the source account. You can use pagination parameters to control the response size, and filter balance changes by `token_id`, `flow_direction`, `min_created_timestamp`, `max_created_timestamp`, `source_type`, or `source_id`. When specifying `source_id`, you must also specify `source_type`. For more information, see [Cobo Payments Guide](https://www.cobo.com/payments/en/guides/overview). ```python Python theme={null} import cobo_waas2 from cobo_waas2.models.list_balance_changes200_response import ( ListBalanceChanges200Response, ) from cobo_waas2.models.payment_balance_change_source_type import ( PaymentBalanceChangeSourceType, ) from cobo_waas2.models.payment_balance_flow_direction import PaymentBalanceFlowDirection from cobo_waas2.rest import ApiException from pprint import pprint # See configuration.py for a list of all supported configurations. configuration = cobo_waas2.Configuration( # Replace `` with your private key api_private_key="", # Select the development environment.
