Breaking Changes

  • v1 API End of Life Notification: No earlier than November 30, 2024, we are sunsetting the Paxos v1 APIs. This change ensures all Paxos customers are using supported APIs. Customers can begin migrating as most functionality available via the v1 APIs is already available in Paxos v2 APIs. The remaining gaps will be closed by mid Q3, 2024. We recommend you test your integrations in Sandbox during the testing window. See Migrating from v1 to v2 API.

  • v2 API: Enable HRQ users to buy and sell PYUSD using the Create Quote Execution endpoint. Allow all HRQ users to retrieve PYUSD using the List Quotes endpoint.
  • v2 API: Add PYUSD to the List Historical Prices endpoint.
  • v1 API: Enable PYUSD withdrawal. All PYUSD withdrawals debit USD balance only. Enable USD deposit auto-conversion to PYUSD withdrawal.
  • v2 API: Enable PYUSD withdrawals using the Transfers API with the option to debit USD balance. Add values asset=PYUSD and balance_asset=USD to the Create Crypto Withdrawal request.
  • Wallet UI: Enable PYUSD withdrawals. All PYUSD withdrawals debit USD balance only. Enable USD deposit Auto-Transfer to PYUSD withdrawal.
  • Docs: Add sourcing and implementation information to the Paxos Documentation.

  • v2 API: Add assets=PYUSD query parameter to List Profile Balances. Add asset=PYUSD path parameter to Get Profile Balances. Add ”asset”: “PYUSD” to Create Sandbox Deposit request body schema. Add PYUSD to properties base_asset, quote_asset, commission_asset and rebate_asset for the List Executions, List Quotes, List Quote Executions, Create Quote Execution and Get Quote Execution endpoints.

  • Docs: Add Held Rate Quotes Quickstart guide, Ledgering Strategy and Orders & Quotes FAQ best practice guides.

  • V2 API: Add a default of 100 results to the limit query parameter and restrict the maximum page limit to 1,000 for the Paxos v2 API List Deposit Addresses service. Learn more.

  • v1 API: Add new schema 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 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.

  • Docs: Add FIX overview, onboarding, certification and best practices documentation.

  • v2 API: Add error code MARKET_CONDITIONS_PREVENTED_EXECUTION to Create Order response.
  • FIX: Add additional detailed failure reason (tag 58) Market conditions have invalidated this order.

Both GetProfileDepositInstructions and GetCryptoAddressAutoconversionInstructions now return NULL no longer return SEN Deposit Instructions nor Silvergate wire deposit instructions. These endpoints still return SigNet Deposit Instructions and memo IDs.
