## Talon.One Klaviyo Integration<ClosedBetaBadge />

Enables data synchronization between Klaviyo and Talon.One.

For more information, see [Integrate with Klaviyo](/docs/dev/technology-partners/klaviyo/integrate-with-klaviyo.md).

## Trigger Rule Engine<ClosedBetaBadge />

Allows you to trigger the Rule Engine when a certain event happens in Talon.One.

Currently, two integrations are available:

- **Trigger Rule Engine: Tier upgrade**: Triggers the Rule Engine when a customer reaches
  a higher loyalty tier.
- **Trigger Rule Engine: Tier downgrade**: Triggers the Rule Engine when a customer moves
  to a lower loyalty tier.

See the [tutorial](/docs/dev/tutorials/create-coupon-on-tier-upgrade.md) on how to set up
this integration and use it.

:::important
Internally, this integration is triggered by the same events that also trigger [loyalty
notifications](/docs/product/loyalty-programs/loyalty-notifications/overview.md) and
[Application
notifications](/docs/product/applications/application-notifications/overview.md).
Therefore, the same limitations apply.

For example, for the tier downgrade integration to work, the profile-based loyalty program
must be set to [scheduled tier
downgrade](/docs/product/loyalty-programs/profile-based/use-loyalty-tiers.md#scheduled-tier-downgrade)
with a [relative expiration
date](/docs/product/loyalty-programs/profile-based/use-loyalty-tiers.md#expiration-type).

For more information, see the [Tier-related
changes](/docs/product/loyalty-programs/loyalty-notifications/overview#tier-changes)
section.
:::

Common use cases include:

- **Issue a welcome coupon**: Create a coupon code for the customer to use on their next
  purchase.
- **Add loyalty points**: Award bonus loyalty points as a reward for reaching the new
  tier.
- **Add the customer to an audience**: Automatically enroll the customer in a
  tier-specific [audience](/docs/product/audiences/overview.md) to unlock targeted
  campaigns.
- **Send a win-back offer**: When a customer drops to a lower tier, issue a discount or
  coupon to encourage them to re-engage.
