Build a Smart Zendesk-Powered AI Agent—No Code Needed

AI agents are great at handling repetitive tasks and freeing up your human team, but what if they could go a step further and tap into your business tools to deliver even smarter interactions?

In this tutorial, André shows you how to build a fully functional AI voice agent that integrates with Zendesk using SignalWire AI Agent functions and Make.com. The result? A voice bot that greets your customers, pulls up their support tickets, and responds based on real-time data, all without writing a single line of backend code.

What You’ll Learn:

  • How AI Agent Functions Work: These let you define specific actions the agent can take using HTTP requests to external services like Zendesk.

  • The “Get User” Function: Uses the caller’s phone number to look up their name and Zendesk user ID.

  • The “Get Latest Ticket” Function: Retrieves the most recent support ticket for the identified user and shares the status on the call.

  • How to Use Make.com: This no-code tool acts as the middleware, processing incoming webhook data and querying Zendesk.

  • How to Set It All Up in SignalWire: You’ll connect the agent to a phone number so your customers can interact with it live.


With SignalWire’s AI Agent + function support, your agents aren’t limited to just scripted responses. They can pull in live data, trigger actions, and update their behavior dynamically based on what they learn during the call. That means better support, faster service, and less time spent by your human reps answering basic questions.
