Vapi is the Voice AI platform for developers.

Vapi AI

The new tool calling interface as well as API reference doesn't show support for enums anymore - temporarily because you're still working on it?
If a tool is created via API with enums, the frontend removes anything related to enums when editing the function.

Enums as per the OAI Spec:

It was working fine before - please look into this ASAP since this is a major issue imo

    "parameters": {

          "type": "string",
          "description": "City and country e.g. Bogotá, Colombia"
        },
        "units": {
          "type": "string",
          "description": "Units the temperature will be returned in.",
          "enum": ["celsius", "fahrenheit"]
        }
      },
      "required": ["location", "units"]

When creating a function tool via the API, you need to follow the OpenAI Function Calling schema format, which Vapi has implemented. Above's how to define an enum in your function parameters.
