Using the connector

To use AscendEX connector, you will need to generate and provide your API key to trade using Hummingbot.

Enter your AscendEx API key >>>
Enter your AscendEx secret API key >>>

Private keys and API keys are stored locally for the operation of the Hummingbot client only. At no point will private or API keys be shared to CoinAlpha or be used in any way other than to authorize transactions required for the operation of Hummingbot.


For copying and pasting into Hummingbot, see this page.

Creating AscendEX API keys

  1. Log in to your account at here, then click your profile > API settings (If you do not have an account, you will have to create one and verify your ID.)


You must enable 2FA in your AscendEX account to create the API key. How to enable 2FA?

  1. Then click the new API key.


For API key permissions, we recommend using trade and view enabled API keys; enabling transfer, or the equivalent is unnecessaryfor current Hummingbot strategies.

  1. Now that you have created an API key, connect it to Hummingbot by using the connect command.

Make sure you store your Secret Key somewhere secure and do not share it with anyone. Your Secret Key will only be displayed once at the time when you create the API.


If you lose your Secret Key, you can delete the API and create a new one. However, it will be impossible to reuse the same API.
