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 of beneficiary_name, account_number, and CustomerBankAccount.Type) as an alternative to existing network-specific intrabank details (account_number can be a wallet address for networks like CBIT).
CustomerBankAccount will fill in IntrabankWithdrawalInstructions IN ADDITION TO the existing intrabank withdrawal instructions in responses. Future intrabank networks will only be supported via IntrabankWithdrawalInstructions (as opposed to their own field). The Type field on IntrabankWithdrawalInstructions will differentiate the network types.
Existing network-specific instructions are deprecated, but will continue to work.
