Connect your AI agent to your APIs and business systems so it can retrieve real-time information, perform actions, and complete customer requests across your CRM, ERP, e-commerce platform, booking system, support software, or any custom application.
Traditional AI chatbots can answer questions using websites, documents, and knowledge bases. But many customer requests require access to live business data. Customers may ask:
Function tool calling lets the agent call the right API automatically, pull the data it needs, and respond or complete the request without a human stepping in.
Your business data can live in more than one place. Your AI agent can reach into your:
You define the API and when it should be used. The agent decides when to call it based on the customer's conversation. Customers don't need to know whether their information lives in the CRM, the e-commerce platform, or an internal database; they just ask, and the agent figures out which system to call.
You're also not limited to prebuilt integrations. If your application exposes an API, you can turn it into a tool the agent can use, which is especially handy for proprietary software or workflows spread across multiple systems.
Configure your API endpoint, method, authentication, parameters, and expected response.
Describe what the function does, e.g. "Use this function when a customer asks about the status of their order."
When a request needs that information, the AI agent identifies the right function and calls your API automatically.
The API response becomes part of the conversation, letting the agent respond or complete the action.
Check orders, inventory, invoices, customer accounts, subscriptions, shipments, appointments, product availability, and more.
Create leads, support tickets, bookings, orders, tasks, or CRM activities.
Update customer profiles, CRM records, appointments, preferences, or workflow statuses.
Start automations, send information to internal applications, initiate approval processes, or invoke external services.
Your AI agent should not stop at “I understand what you need.”
With function tool calling, it can move to “I’ve done it for you.”
