Vapi Python SDK

This package lets you start Vapi calls directly in your Python application.

Installation

You can install the package via pip:

pip install vapi_python

On Mac, you might need to install brew install portaudio to satisfy pyaudio's dependency requirement.

Usage

First, import the Vapi class from the package:

from vapi_python import Vapi

Then, create a new instance of the Vapi class, passing your Public Key as a parameter to the constructor:

vapi = Vapi(api_key='your-public-key')

You can start a new call by calling the start method and passing an assistant object or assistantId. You can find the available options here: docs.vapi.ai

vapi.start(assistant_id='your-assistant-id')

or

assistant = {
  'firstMessage': 'Hey, how are you?',
  'context': 'You are an employee at a drive thru...',
  'model': 'gpt-3.5-turbo',
  'voice': 'jennifer-playht',
  "recordingEnabled": True,
  "interruptionsEnabled": False
}

vapi.start(assistant=assistant)

The start method will initiate a new call.

You can override existing assistant parameters or set variables with the assistant_overrides parameter. Assume the first message is Hey, {{name}} how are you? and you want to set the value of name to John:

assistant_overrides = {
  "recordingEnabled": False,
  "variableValues": {
    "name": "John"
  }
}

vapi.start(assistant_id='your-assistant-id', assistant_overrides=assistant_overrides)

You can stop the session by calling the stop method:

vapi.stop()

This will stop the recording and close the connection.
