# 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. The `datastreams` reference used in the code below is the [component instance](https://docs.catalyst.zoho.com/en/sdk/nodejs/v2/cloud-scale/data-streams/get-component-instance) created earlier.

### Get Token Pair using Connection Name

You can generate 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. The promise returned here will be resolved to a token pair object.

**Parameters Used**

<table class="content-table">
	<thead>
		<tr>
			<th class="w20p">Parameter Name</th>
			<th class="w20p">Data Type</th>
			<th class="w60p">Definition</th>
		</tr>
	</thead>
	<tbody>
		<tr>
			<td>`channelId`</td>
			<td>**String**</td>
			<td>A **Mandatory** parameter. Holds the unique ID of the channel.</td>
		</tr>
		<tr>
			<td>`connectionName`</td>
			<td>**String**</td>
			<td>A **Mandatory** parameter. Holds the custom identifier for the subscriber connection.</td>
		</tr>
	</tbody>
</table>

```javascript
//Generate token pair using connection name
const response = await datastreams.getTokenPair(CRICKET_CHANNEL_ID, {
  connectionName: "cricketScoreUpdates"
});
```

### Get Token Pair using User ID

Alternatively, you can generate 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. The promise returned here will be resolved to a token pair object.

**Parameters Used**

<table class="content-table">
	<thead>
		<tr>
			<th class="w20p">Parameter Name</th>
			<th class="w20p">Data Type</th>
			<th class="w60p">Definition</th>
		</tr>
	</thead>
	<tbody>
		<tr>
			<td>`channelId`</td>
			<td>**String**</td>
			<td>A **Mandatory** parameter. Holds the unique ID of the channel.</td>
		</tr>
		<tr>
			<td>`userId`</td>
			<td>**String**</td>
			<td>A **Mandatory** parameter. Holds the unique ID of the user subscribing to the channel.</td>
		</tr>
	</tbody>
</table>

```javascript
//Generate token pair using user ID
const response = await datastreams.getTokenPair(CRICKET_CHANNEL_ID, {
  userId: "userId"
});
```
