Reconciliation Reporting: As part of reconciliation reporting improvements, we are incrementally rolling out a few changes to the Profile Balances Report.
-
The report no longer lists assets in ordered asset order. New order will be
balance_attime (start time then end time) first, and asset alphabetical second. - The report now shows assets as long as there is one transaction that happened in history, even if no transactions in the asset were reported during the reporting period. Previously, assets with balances would show up in the report only if there was a transaction in the reporting period or if the asset was pre-configured to show up in the report regardless of transaction history.

IntrabankDepositInstructions and new field PaxosBankAccount to the GetProfileDepositInstructions endpoint. IntrabankDepositInstructions includes fields memo_id, beneficiary_name account_number, and type. PaxosBankAccount:intrabank is a generic IntrabankDepositInstructions that populates whenever any of the other intrabank type fields (for example, cbit) are populated (the respective existing fields will also be populated and supported). Future intrabank networks will be contained in intrabank only. v1 API:
CreateBankAccount endpoint and CustomerBankAccount schema have a new optional field: IntrabankWithdrawalInstructions. - This generalizes the existing intrabank withdrawal instructions into a single field. Clients may specify the new
IntrabankWithdrawalInstructions(which consist ofbeneficiary_name,account_number, andCustomerBankAccount.Type) as an alternative to existing network-specific intrabank details (account_numbercan be a wallet address for networks like CBIT). CustomerBankAccountwill fill inIntrabankWithdrawalInstructionsIN ADDITION TO the existing intrabank withdrawal instructions in responses. Future intrabank networks will only be supported viaIntrabankWithdrawalInstructions(as opposed to their own field). The Type field onIntrabankWithdrawalInstructionswill differentiate the network types.- Existing network-specific instructions are deprecated, but will continue to work.
