This article is part of a guide on getting started with Voiceflow APIsStart from the beginning here.
To use Voiceflow APIs, the first thing you need is your API key. The same Voiceflow Project API key can be used for all Voiceflow APIs.
Every Voiceflow Project has its own unique API key.
Find your Voiceflow API Key
- Open your Voiceflow Project
- Open 'Settings', then go to 'API Keys'
- Your 'primary key' is your Project's API key
- Copy it - and you're good to go!

To learn more about API keys, see this article about authentication.
👉 Copy your API key and add it as a constant at the top of your Python file.
import requests
api_key = 'YOUR_API_KEY_HERE' # it should look like this: VF.DM.XXXXXXX.XXXXXX... keep this a secret!
const axios = require('axios');
const api_key = 'YOUR_API_KEY_HERE'; // it should look like this: VF.DM.XXXXXXX.XXXXXX... keep this a secret!
