+# openvidu-backend-client
+Java package that wraps the HTTP REST operations of openvidu-server.
+
+- Maven dependency
+	```xml
+	<dependency>
+	    <groupId>io.openvidu</groupId>
+	    <artifactId>openvidu-java-client</artifactId>
+	    <version>...</version>

+	[```https://github.com/OpenVidu/openvidu/tree/master/openvidu-java-client/target/openvidu-java-client.jar```](https://github.com/OpenVidu/openvidu/tree/master/openvidu-java-client/target/openvidu-java-client.jar)
+
+The usage is quite simple: import OpenVidu package and get an **OpenVidu** object. You need to provide to the constructor the IP of your OpenVidu Server and the secret shared with it (initialized by `openvidu.secret=MY_SECRET` property). Then just call the following methods to get a shiny new sessionId or token to be returned to your frontend.
+
+
+```java
+import io.openvidu.java.client.OpenVidu;
+
+OpenVidu openVidu = new OpenVidu(OPENVIDU_SERVER_IP, YOUR_SECRET);
+
+Session session = this.openVidu.createSession();
+String sessionId = session.getSessionId();
+String token = session.generateToken();
+// Send sessionId and token to frontend
+```
