If your store already collects customer birth dates using a custom metafield, for example, through a registration app, theme customization, or a third-party form, this data will not sync with Growave automatically. As a result, birthday rewards won't be triggered through Growave.
To ensure Growave can access customer birth dates and send automated birthday rewards, your store must use Shopify’s default metafield definition:
Name: Birth date
Key:
facts.birth_date
How the sync works
Once the facts.birth_date metafield is present in your store, Growave and Shopify will sync birth dates automatically in both directions:
Action | Result |
Customer enters birth date via Growave widget on storefront | Data saved in Shopify under the existing standard metafield |
Admin adds birthday via Growave → Customers | Metafield is updated in Shopify |
Admin adds birthday in Shopify Customer profile | Date appears in Growave automatically |
📗 Note
If the Birth date metafield (facts.birth_date) does not exist in Shopify after you install Growave, you can create it by:
Activating the Celebrate birthday rule under Rewards → Points → Ways to earn.
Creating a test customer account and adding a birthday to it in Growave → Customers → Customer profile.
Replace your custom metafield with the standard one
If you previously used a custom metafield to collect birthdays (e.g., customer_birthday, birth_date_custom, etc.), it won’t work with Growave.
To fix this:
In your Shopify admin, go to Settings → Metafields and metaobjects.
Open Customer metafields and check if the Birth date with the key
facts.birth_dateexists.If not, create it manually:
Click Add definition and name it Birth date.
Shopify will suggest the standard definition with key
facts.birth_date. Select it.Under Customer Account API access, choose Read and write.
Click Save.
Once saved, the metafield will be available for syncing with Growave and can also be used for storefront personalization.
Update your registration forms, theme code, or app integrations to use this standard metafield instead of your previous one.
