More updates
Enhancements:
  • Achievements: In the attribute selector of the Rule Builder, you can now search for attributes by achievement ID.
  • Experiments: Updated terminology for experiments in the Campaign Manager.
  • Integrations: The new Integration Hub status page shows the status of your instances and the events sent to them.
  • Loyalty:
    • pointsToNextTier and nextTierName are now available as built-in attributes in the Rule Builder, custom effects, and webhook payloads. Both attributes are based on values from the Get customer's loyalty balances endpoint.
    • You can now include the subledgerId query parameter in the Export customer loyalty balances endpoint to filter exported loyalty balance data by a specific subledger.
  • Notifications: Added the pageSize parameter to the List message log entries endpoint. This parameter allows you to configure the number of message log entries to return.
  • Rewards:
    • You can now search and filter the Rewards list by name, Application, and status.
    • You can now retrieve rewards information from the Track advanced event endpoint and the Update customer profile endpoint by including unlockedRewards in the responseContent or rewardIntegrationIds in the request.
    • You can now retrieve all the rewards associated with a customer profile using the List customer's rewards endpoint. This endpoint returns both unlocked and used rewards.
  • Strikethrough pricing: Lowered the minimum payload size of notification requests to 50 items for strikethrough pricing updates to prevent integration errors.
  • Integration API: Responses for the Create coupon reservation and List customers that have this coupon reserved endpoints now include the timestamp of when a coupon reservation was created.
  • Coupons: Increased the coupon redemption limit to 10,000,000 for random codes and universal codes.
Bug fixes:
  • Achievements: Fixed a bug where the ID of an account-level achievement was not shown in the Conditions section of the Rule Builder.
  • Strikethrough pricing notifications: Fixed a bug where importing data into a collection triggered an unwanted strikethrough pricing update when the collection was referenced in an already expired campaign.
  • Experiments:
    • Fixed an error that occurred when copying an experiment with no rules.
    • Fixed an issue where experiment analytics didn't include sessions for variants whose effects don't change the session, such as adding a customer to an audience.
