👉👉Important Upgrade👈👈

We have recently upgraded apikey from the previous v2 version of apikey to v3.

We have automatically migrated some of the apikeys to the v3 version. Please check your apikey version (https://www.kucoin.com/account/api). If it is still a v2 apikey, please upgrade to the v3 version as soon as possible. We will invalidate the v2 version of apikey in batches from July 1st to July 10th. By then, the v2 version of apikey will not be available.

Upgrade method:

This upgrade method is a compatible upgrade, which does not require the client to modify any code. It only needs to re-create a new version of v3 apikey and replace the old version of v2 apikey.
