Capture & Store Customer Birthdays from Registration to Metafields

Manually collecting birthday data is a time-sink, prone to errors, and often leads to missed opportunities for delightful, personalized marketing. Without this key data in a structured format, you're forced into generic promotions, losing out on higher engagement and conversion rates that come from timely, relevant birthday offers.

This Flow automates the entire process: when a new customer is created, it triggers the workflow. A 'Run code' action then intelligently extracts the birthdate from the customer's note (where registration apps often store it), and finally, an 'Update customer metafield' action saves this crucial data directly to a dedicated `birth_date` metafield on the customer profile.

• You offer birthday discounts, special promotions, or loyalty rewards.
• You want to segment your customer base by age or birth month for highly targeted marketing.
• You're committed to delivering personalized communication and product recommendations to enhance customer relationships.

1. 1

   Create a new Shopify Flow and select the 'Customer created' trigger.

2. 2

   Add an 'Run code' action. Configure it to parse and extract the birthdate string from the customer's note field.

3. 3

   Include an 'Update customer metafield' action. Set it to save the extracted birthdate value to a new or existing customer metafield (e.g., `namespace: custom`, `key: birth_date`).

How do I ensure the birthday is collected during registration?

You'll need a registration form that includes a birthday field, usually added by a third-party app, configured to save this input to the customer's note field when they sign up.

What date format should the 'Run code' action expect?

The 'Run code' action should be written to gracefully handle various date formats (e.g., MM/DD/YYYY, YYYY-MM-DD) that your registration form might submit, converting it to a consistent format for the metafield.

How can I use this birthday metafield for marketing campaigns?

Once saved to a metafield, integrate with your email or SMS marketing platform (like Klaviyo) to create customer segments based on birth month and automate personalized birthday messages or special offers.

What happens if a customer doesn't provide their birthday?

The 'Run code' action should include logic to check if the birthday is present in the note. If not found, it can simply skip updating the metafield, ensuring the Flow completes without errors.
