+# User Data Streams Connect
+
+-   The base API endpoint is: **[https://fapi.binance.com](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.
+    
+-   The connection method for Websocket：
+    
+    -   Base Url: **wss://fstream.binance.com**
+    -   User Data Streams are accessed at **/ws/<listenKey>**
+    -   Example: `wss://fstream.binance.com/ws/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**
+    
+-   A single connection is only valid for 24 hours; expect to be disconnected at the 24 hour mark
