Calling Convention of V2 API

Dear KuCoin Users,

KuCoin has upgraded the API KEY to version 2.0 and has stopped supporting the API KEY of version 1.0. To further standardize the way of API called, KuCoin will cancel the compatible handling of the wrong transmission request header on January 1st, 2022 (UTC).

Please strictly follow the API document to transmit the fields in the request header, the details as follows:

For API key-V2.0, please Specify KC-API-KEY-VERSION as 2 --> Encrypt passphrase with HMAC-sha256 via API-Secret --> Encode contents by base64 before you pass the request.

For more information, please check the KuCoin API KEY upgrade operation guide .

The above adjustment includes KuCoin and KuCoin Futures!

We apologize for any inconvenience caused and thank you for your patience！

Thanks for your support!

The KuCoin Team
