Overview

Data privacy and security starts with safekeeping of sensitive secrets and keys. Whether you’re using API keys or tokens, handling these properly is critical. Our vault ensures that your keys stay private to you and don’t get shared with anyone else.

​

Storing keys and secrets

Simply navigate to Settings > Secrets.

To save your first secret, click on + Add Secret.

Then:

1. Under Name, put in the name you want to use for your secret (eg. SLACK_TOKEN)
2. Optionally include a description under Description
3. Copy/paste your secret under Secret then click Add Secret

​

Using secrets

Once you’ve saved a key or secret, to use it, you can reference it in any cell following this convention: fabi.secret.MY_SECRET.

Here’s an example using a secret to store a key for the Polygon.io API:

def get_stock(api_key):
    url = f"https://api.polygon.io/v2/aggs/ticker/AAPL/range/1/day/2025-04-01/2025-05-15?apiKey={api_key}&sort=asc"
    data = requests.get(url).json().get('results', [])
    df = pd.DataFrame(data)
    if not df.empty:
        df['date'] = pd.to_datetime(df['t'], unit='ms')
        df = df[['date', 'c']]
        df.columns = ['date', 'price']
    return df

# Using the existing API key
api_key = fabi.secret.POLYGON_KEY
stock = get_stock(stock)
display(stock)
