OKX Broker has launched the Fast API function to provide additional security to the API Key binding process. As a user connecting to trade with OKX on our brokers' platform, Fast API allows users to log in through OAuth mode and authorize the access token to generate API Keys automatically on behalf of the user. Benefits Swift and safe: Users no longer need to copy their OKX API Key and API Secret manually, just log in to the OKX account and connect to the preferred broker. . Secure IP whitelist for supported brokers: The automatically generated API Key will only have users' connected Broker's IP addresses whitelisted. In unfortunate circumstances where the API Key gets hacked on the Broker's side, the hacker cannot easily exploit the users' API Key since OKX only accepts requests coming from Broker's whitelisted servers. .
