SPOT Margin HF Migration Completed
Parameter Unification & LF Endpoint Deprecation

Note: To understand the background and migration plan for this change, please read KuCoin’s previously published announcement “KuCoin Margin API Upgrade Announcement”:
https://www.kucoin.com/announcement/kucoin-margin-notice-250702

KuCoin Margin APIs have completed the high-frequency (HF) migration. All low-frequency (LF) accounts for SPOT Margin have been migrated to HF accounts. Effective immediately, please use HF APIs for SPOT Margin trading and related operations.

Change Summary

Preferred parameters: Use non-V2 account type parameters for SPOT Margin (margin, isolated).

V2 parameters: margin_v2, isolated_v2 have the same meaning as non-V2 parameters, but will be gradually replaced by non-V2 parameters.

LF order endpoints disabled: Some LF Margin order endpoints under Abandoned Endpoints are no longer available.

Affected Endpoints

#	Endpoint	Parameter Mapping & Notes (All refer to SPOT Margin HF accounts)	Change
1	Classic REST - Get Transfer Quotas	Preferred: `MARGIN`, `ISOLATED` V2: `MARGIN_V2`, `ISOLATED_V2` (same meaning; phased out gradually)	Queries for SPOT Margin LF accounts are no longer supported.
2	Classic REST - Flex Transfer	Preferred: `MARGIN`, `ISOLATED` V2: `MARGIN_V2`, `ISOLATED_V2` (same meaning; phased out gradually) Rule: When `type` is `INTERNAL`, non-V2 and V2 are equivalent. When `type` is not `INTERNAL`, `MARGIN_V2` and `ISOLATED_V2` are not supported—use `MARGIN` and `ISOLATED`.	Transfers between SPOT Margin LF and HF accounts are no longer supported.
3	Classic REST - Get Account - Cross Margin	Preferred: `MARGIN` V2: `MARGIN_V2` (same meaning; phased out gradually)	Parameter semantics unified: `MARGIN` represents HF Cross Margin; `MARGIN_V2` will be phased out.
4	Classic REST - Get Account - Isolated Margin	Preferred: `ISOLATED` V2: `ISOLATED_V2` (same meaning; phased out gradually)	Parameter semantics unified: `ISOLATED` represents HF Isolated Margin; `ISOLATED_V2` will be phased out.
5	Classic REST - Get Account Ledgers - Margin_hf	Response field: `accountType` Current: `MARGIN_V2`, `ISOLATED_V2` Next: `MARGIN`, `ISOLATED` (will gradually replace the V2 values)	Response field update: `accountType` currently returns V2 enum values and will gradually migrate to non-V2 enum values.
6	Abandoned Endpoints - Inner Transfer	Preferred: `margin`, `isolated` V2: `margin_v2`, `isolated_v2` (same meaning; phased out gradually)	Transfers between SPOT Margin LF and HF accounts are no longer supported.
7	Abandoned Endpoints - Add Order - V1	N/A (Margin LF order placement endpoint; no HF parameter mapping)	SPOT Margin LF endpoint is no longer available.
8	Abandoned Endpoints - Add Order Test - V1	N/A (Margin LF test order endpoint; no HF parameter mapping)	SPOT Margin LF endpoint is no longer available.
9	Abandoned Endpoints - Get Account List - Isolated Margin - V1	N/A (Margin LF isolated account list endpoint; no HF parameter mapping)	SPOT Margin LF endpoint is no longer available.
10	Abandoned Endpoints - Get Account Detail - Isolated Margin - V1	N/A (Margin LF isolated account detail endpoint; no HF parameter mapping)	SPOT Margin LF endpoint is no longer available.

Developer Action Items (Recommended)

Use non-V2 account type parameters: MARGIN, ISOLATED.

Keep compatibility for *_V2 parameters for now, but plan to remove dependencies as they will be gradually replaced by non-V2 parameters.

For Classic REST - Flex Transfer: use MARGIN, ISOLATED for non-INTERNAL transfers; V2 is only equivalent when type=INTERNAL.

For Abandoned Endpoints - Inner Transfer: parameters must be lowercase: margin, isolated, margin_v2, isolated_v2.

Stop calling disabled Margin LF order endpoints (Abandoned Endpoints).

2026.02.15

[Exchange Broker Modify] Add sub-account API, Modify sub-account API endpoints have been updated. The permissions field now includes four new enum permissions: Margin, InnerTransfer (Universal Transfer), Transfer (Withdrawal), and Earn.

With the updated permission structure, the special sub-accounts of exchange brokers now additionally support:

Margin Trading,

Fund transfers between different types of accounts(please note: only transfer-within-account is currently supported),

Direct withdrawals from sub-accounts,

Earn (wealth management) services

At the same time,the KuCoin Convert feature is now accessible to special sub-accounts, provided that the broker has activated the Convert permission on their main account and the API permission of sub-accounts includes Spot.Learn more about KuCoin Convert: https://www.kucoin.com/convert

Existing integrations remain compatible. However, exchange brokers wishing to enable the new features must explicitly configure the corresponding permissions via Modify sub-account API endpoint.
