# Changelog

<Update label="29 July 2025">
  ## Set customer birthdays and subscribe to email marketing

  * The [Set Birthday](/headless-api/2025-06/customers/set-birthday) endpoint
    can be used to set a customer's birthday, so you can capture it as part of
    your storefront or mobile app and send it to LoyaltyLion where it can be used
    to gift a customer points or a reward for their birthday

  * The [Subscribe to Email Marketing](/headless-api/2025-06/customers/subscribe-email-marketing)
    endpoint can be used to subscribe a customer to email marketing. This is limited
    to Shopify stores for now, and will update the customer's email marketing consent
    with Shopify. If applicable rules are configured, they will be automatically
    triggered, such as awarding a customer with points or a reward for subscribing

  ## Complete rules for customers

  Complete interactive rules for customers using a set of new endpoints:
  [Clickthrough](/headless-api/2025-06/complete-rules/clickthrough),
  [Facebook Like](/headless-api/2025-06/complete-rules/facebook-like),
  [Instagram Follow](/headless-api/2025-06/complete-rules/instagram-follow),
  [TikTok Follow](/headless-api/2025-06/complete-rules/tiktok-follow),
  [Twitter/X Follow](/headless-api/2025-06/complete-rules/twitter-follow),
  [Custom](/headless-api/2025-06/complete-rules/custom)

  These endpoints should be called once the customer has completed the relevant
  action, such as visiting a URL, liking a Facebook page or following a TikTok user,
  and will immediately complete the rule for the customer and award them points
  or a reward, assuming they're eligible.
</Update>

<Update label="17 July 2025">
  ## Customer history

  Endpoints that return a Customer object, such as the
  [Get Customer](/headless-api/2025-06/customers/get-customer) API and reward
  redemption endpoints, now return the customer's recent point, tier and reward history
  under the `customer.history` property.
</Update>

<Update label="8 July 2025">
  ## Free product rewards

  The Headless API now supports the redemption of free product rewards when
  used with a Shopify storefront.

  See the [Free Product redemption](/headless-api/2025-06/reward-redemption/free-product)
  endpoint, and our [implementation guide](/headless-api/guides/hydrogen/free-product-rewards) for Shopify Hydrogen.

  If you're using a different frontend framework, you can still redeem free
  products (it's not Hydrogen specific). Review the Hydrogen guide for an overview
  and adapt to your framework, or get in touch with us if you need help.
