# Configure a route

The routing section enables you to link the workflows you've built to the messaging channels you want to use. 

You can define the workflow and step that gets triggered when a customer for example dials a certain USSD code or messages your WhatsApp Business account. 

{% hint style="info" %}
You can only set up routes for the channels that are set up in your Clickatell account. You can add one or more routes for each of your channels. 
{% endhint %}
