Got it, let's walk through exactly how to get your holiday-check script working with Zap Storage, then use that value to control your Zap's flow with a filter.

Step 1: Set Up the Python Code Action in Zapier #

First, you'll need to run your script using Zapier's built-in code tool, and modify it to save the holiday_value to Zap Storage:

1. Start a new Zap (or edit an existing one) and add your initial trigger (I'd recommend Schedule by Zapier set to run daily, since you're checking the current day's holiday status).
2. Add an Action step, search for and select Code by Zapier, then choose Python as the runtime.
3. Replace the default code with your script, plus the line to save to Zap Storage. Here's the updated version:

from datetime import date
import holidays

us_holidays = holidays.US()
if date.today() in us_holidays:
    holiday_value='true'
else:
    holiday_value='false'

# Save the value to Zap Storage (persists across Zap runs)
storage['is_holiday'] = holiday_value

# Optional: Return the value so it's visible in Zap's data pipeline for debugging
return {'is_holiday': holiday_value}

• The storage object is a built-in Zapier tool for persistent key-value storage. Using storage['is_holiday'] = holiday_value saves your flag so you can access it later—either in the same Zap or a separate one.
• The return line isn't strictly required, but it makes the is_holiday value directly available to subsequent steps in your Zap, which simplifies setting up the filter.

Step 2: Access the Stored Value (If Needed) #

• In the same Zap: You can skip this—just use the output from the Code step directly (it'll show up as a data field labeled something like Return Value > is_holiday).
• In a separate Zap: Add another Code by Zapier Python step, and use this line to retrieve the value:

  # Get the stored value; default to 'false' if it doesn't exist
  is_holiday = storage.get('is_holiday', 'false')
  return {'is_holiday': is_holiday}
  

Step 3: Set Up the Zap Filter #

Now use the holiday_value to control whether your Zap proceeds:

1. Add a Filter by Zapier step right after your Code action.
2. Configure the filter rules:
   • Select the is_holiday field from your Code step's output.
   • Choose the condition Exactly matches.
   • Enter true (if you want the Zap to run only on holidays) or false (if you want it to run only on non-holidays).
3. Save the filter—now your Zap will only continue executing subsequent steps if the condition is met.

Quick Notes #

• Double-check that the holidays library is available in Zapier's Python runtime. If you run into an import error, you might need to use an alternative method to check US holidays (like leveraging a pre-installed library or a simple date lookup for major holidays).
• Zap Storage is tied to your Zapier account, so the is_holiday key will persist until you overwrite or delete it.
