API Kraken Futures | WebSockets Private API

Connection

URL: wss://futures.kraken.com/ws/v1

 

Authentication

The subscribe and unsubscribe requests to WebSocket private feeds require a signed challenge message with the user api_secret.

The challenge is obtained as is shown in Section WebSocket API Public (using the api_key).

Authenticated requests must include both the original challenge message (original_challenge) and the signed (signed_challenge) in JSON format.

In order to get a Websockets Challenge, an API Key and API Secret must be set in Kraken Options Component, the api key provided by Kraken in your account

  
Kraken.ApiKey := 'api key';
Kraken.ApiSecret := 'api secret';
