# 替换已使用的促销码

当推荐中使用了倡导者代码时，该代码会被标记为已使用，并会从您可用的代码中自动分配 1 个替换代码。您无需进行任何操作。

* 代码会在每个代码被使用时逐个替换。
* 替换功能仅在您还有未使用的代码时有效。如果您用完了，倡导者将无法获得新代码，直到您 [上传更多](/brand/zh/what-would-you-like-to-learn-about/advocate-program/advocate-rewards/referral-promo-codes-for-participants/set-up-referral-promo-codes.md).

## **给参与者额外添加一个代码**

在特殊情况下，您可以在参与者已分配的代码之外，再给他们一个代码：

1. 转到 **参与者** 并选择该参与者。
2. 选择 **代码和链接** 选项卡。
3. 选择 **添加推荐代码**.

该代码会添加到他们小组件中现有的代码里。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://help.impact.com/brand/zh/what-would-you-like-to-learn-about/advocate-program/advocate-rewards/referral-promo-codes-for-participants/replace-used-promo-codes.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
