# 概述

Reward chains encourage users to make purchases in the store using real currency. For each purchase, users earn value points and progress through a reward chain. If users are part of clans, their purchases contribute value points to the entire clan. For detailed information on configuring the reward chains, refer to the [Reward system](https://developers.xsolla.com/zh/liveops/promotion-tools/reward-system/) section.

To configure reward chains, use API calls from the **Admin** subsection. To display chains and claim rewards, use API calls from the **Client** subsection. To work with clan reward chains, use API calls from the **Clans client** subsection.

<b>Example of reward chain configuration flow:</b>

1. Create items using the API calls from the **Admin** subsection of the [Virtual items and currency](https://developers.xsolla.com/zh/api/catalog/virtual-items-currency-overview) or [Bundles](https://developers.xsolla.com/zh/api/catalog/bundles-admin) groups.
2. Create value points using the [Create value point](https://developers.xsolla.com/zh/api/liveops/reward-chain-value-points-admin/admin-create-value-points) API call.
3. Assign value points to items using the [Set value points for items](https://developers.xsolla.com/zh/api/liveops/reward-chain-value-points-admin/admin-set-items-value-point-reward) API call. Users receive value points after purchasing these items.
4. Create a chain using the [Create reward chain](https://developers.xsolla.com/zh/api/liveops/reward-chain-value-points-admin/admin-create-reward-chain) API call. To activate the chain, pass the `is_enabled: true` parameter.
5. Implement reward chain display. To do this, request the list of available chains using the [Get current user's reward chains](https://developers.xsolla.com/zh/api/liveops/reward-chain-client/get-reward-chains-list) API call. The response contains all active chains with their steps and statuses.
6. Implement value point balance display. To do this, use the [Get current user's value point balance](https://developers.xsolla.com/zh/api/liveops/reward-chain-client/get-user-reward-chain-balance) API call.
7. Implement step reward claiming. To do this, use the [Claim step reward](https://developers.xsolla.com/zh/api/liveops/reward-chain-client/claim-user-reward-chain-step-reward) API call.
8. Configure order status tracking, e.g., using [webhooks](https://developers.xsolla.com/zh/webhooks/section/overview), to promptly receive data on claimed rewards and grant them to the user.
