<a name="use-channel-contact-attribute"></a>

You can personalize the customer's experience based on the channel that they use to contact you. Here's what you do: 

1. Add a **Check contact attributes** block to the beginning of your flow.

1. Configure the block as shown in the following image. In the **Attribute to check** section, set **Type** to **System**, set **Attribute** to **Channel**. In the **Conditions to check** section, set it to **Equals CHAT**.

1. The following image of the configured Check contact attributes block shows two branches: **CHAT** and **No Match**. If the customer is contacting you through chat, specify what should happen next. If the customer is contacting you through a call (No Match), specify the next step in the flow.
