Announcement on Delay of API Key Upgrade

07/11/2024, 08:15:07

Dear KuCoin API users,

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. 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 2024.08.01 - 2024.08.10. 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.

How to switch to v3?

Step 1: Open ApiKey Management Page: https://www.kucoin.com/account/api

Step 2: Click on the “avatar” and click “API Management”

Step 3: If the version is V3, it can be used normally. If the version number is v2, we need to recreate a new apikey and replace it. (As shown in the figure, the second apikey needs to be updated).

Step 4: Click Create API.

Step 5: Enter the appropriate info and click “Next”.

Step 6: Enter the appropriate info and click“Confirm”

Step 7: After creating a new apikey, please keep it properly and do not share it with anyone else, even KuCoin customer service staff.

Step 8: After creating the new APIKEY, delete the v2 version of the apikey and use the new one.
