# Generate Token Pair

Before a client can subscribe to a [Data Streams](https://docs.catalyst.zoho.com/en/cloud-scale/help/data-streams/introduction/) channel, it must obtain a token pair to authenticate the WebSocket connection. The token pair can be generated using either a user ID or a connection name.

You can generate the token pair in two ways as described in this section.

### Get Token Pair using User ID

This method generates a token pair by passing the channel ID and the user ID to the `getTokenPair()` method. The user ID represents the unique identifier of the application user who is subscribing to the channel.

#### Sample Code Snippet

**Package Imports**

```java
import com.zc.component.datastream.ZCDatastream;
import com.zc.component.datastream.beans.ZCTokenResponse;
```

```java
//Create a Data Streams instance
ZCDatastream datastream = ZCDatastream.getInstance();
//Define channel ID and user ID
String channelId = "CHANNEL_ID";
Long userId = 30772000000631094L;
//Generate token pair using user ID
ZCTokenResponse tokenResponse = datastream.getTokenPair(channelId, userId);
```

### Get Token Pair using Connection Name

This method generates a token pair by passing the channel ID and a connection name to the `getTokenPair()` method. The connection name is a custom identifier for the subscriber connection.

#### Sample Code Snippet

**Package Imports**

```java
import com.zc.component.datastream.ZCDatastream;
import com.zc.component.datastream.beans.ZCTokenResponse;
```

```java
//Create a Data Streams instance
ZCDatastream datastream = ZCDatastream.getInstance();
//Define channel ID and connection name
String channelId = "CHANNEL_ID";
String connectionName = "CONNECTION_NAME";
//Generate token pair using connection name
ZCTokenResponse tokenResponse = datastream.getTokenPair(channelId, connectionName);
```
