The Add New Integration feature lets you integrate external applications or APIs with your SigmaMind AI agent by creating custom tool actions. This is especially useful when the application you want to use (such as Zendesk or any other service) is not already available in the SigmaMind AI Marketplace. By adding a custom tool, you enable your agent to communicate directly with external systems, send and retrieve data, and perform real-world operations automatically during conversations. You can:
  • Add a new custom app
  • Create custom tool actions
  • Define dynamic input variables
  • Test API actions
  • Embed and use tools inside your AI agent
This enables your Voice AI agent to perform real-world actions such as booking, rescheduling, fetching data, updating records, and more.

​
Step 1: Add New Integration

If your app is not available in the marketplace, you can create a custom tool.

The response contains an integrationId. Save it — every subsequent auth and tool call requires it.
