User Data Streams Connect

  • The base API endpoint is: https://fapi.binance.com

  • A User Data Stream listenKey is valid for 60 minutes after creation.

  • Doing a PUT on a listenKey will extend its validity for 60 minutes, if response -1125 error "This listenKey does not exist." Please use POST /fapi/v1/listenKey to recreate listenKey.

  • Doing a DELETE on a listenKey will close the stream and invalidate the listenKey.

  • Doing a POST on an account with an active listenKey will return the currently active listenKey and extend its validity for 60 minutes.

  • There are two connection methods for Websocket：

    • Base Url 1: wss://fstream.binance.com

    • User Data Streams are accessed at /ws/\<listenKey>

    • Example: wss://fstream.binance.com/ws/XaEAKTsQSRLZAGH9tuIu37plSRsdjmlAVBoNYPUITlTAko1WI22PgmBMpI1rS8Yh

    • Base Url 2: wss://fstream-auth.binance.com

    • User Data Streams are accessed at /ws/\<listenKey>?listenKey=\<validateListenKey>

    • \<validateListenKey> must be a valid listenKey when you establish a connection

    • Example:

    • wss://fstream-auth.binance.com/ws/XaEAKTsQSRLZAGH9tuIu37plSRsdjmlAVBoNYPUITlTAko1WI22PgmBMpI1rS8Yh？listenKey=XaEAKTsQSRLZAGH9tuIu37plSRsdjmlAVBoNYPUITlTAko1WI22PgmBMpI1rS8Yh

  • For one connection(one user data), the user data stream payloads can guaranteed to be in order during heavy periods; Strongly recommend you order your updates using E
