API Updates for Margin Trading

Dear KuCoin Margin API Users,

KuCoin margin high-frequency API will undergo a non-stop system upgrade at 8:00:00 AM (UTC) on January 24, 2024. The upgrade time takes 30 minutes. In this upgrade, we will standardize the format of high-frequency magin trading error codes and add a series of new error codes. The new error codes will become effective immediately after the upgrade completes.

If you only trade spot, futures, or only use margin low-frequency accounts, this update will not impact you.
For specific error codes, please refer to the document: https://www.kucoin.com/docs/basic-info/errors-code/margin-errors-code

If there is a large market fluctuation before the upgrade, we may postpone the upgrade according to the market change and post announcement notice.
For more API communication or feedback, please join our official api telegram group: https://t.me/KuCoin_API or send email to newapi@kucoin.plus.
We apologise for the inconvenience!

Thank you for supporting KuCoin Margin!

The KuCoin Margin Team
