Custom AI Functions
The AI calls your APIs in real time
Defines custom functions that the AI can perform during the conversation. Checks availability, makes reservations, verifies prices, and more.
What is Function Calling?
It is a technique that allows AI to execute functions defined by you during a conversation. You define what data needs to be extracted from the message and which endpoint of your API it should call.
When the AI detects that the customer needs something that requires external data (such as availability, prices, or reservations), it automatically executes the function and includes the result in its response.
Workflow
Client asks
"Is there availability for Friday?"
AI detects intent
Extract: date = Friday
Call your API
GET /availability?date=2026-01-10
Informed response
"Yes, there is availability at 10:00 and 16:00"

See technical documentationFrequently Asked Questions
Do I need to know how to program?
To set up the functions, no, but you need to have an API to connect to. If your system has an API, you can connect it.
How many functions can I create?
There is no limit. You can create as many as you need to cover all use cases of your business.
Does it work with Autopilot?
Yes. When the Autopilot responds, it can perform functions if necessary to provide an informed response.
What happens if my API fails?
WAzion retries automatically. If it continues to fail, the AI responds without that information and you can see the error in the Dashboard logs.
