# Top-Up API 请求
该消息用于通知合作伙伴，Codashop 的一笔购买已成功完成。合作伙伴应据此将指定的物品成功充值至用户的游戏账户。
Codashop 期望在 5 秒内收到响应。该过程应具备幂等性，即对两次相同调用的响应应保持一致，避免触发多次充值。
需要注意的是，充值请求中使用的 ID、txnId 和 orderId 可能与对应购买验证请求中的不同。充值应仅基于 SKU 来完成。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.
## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.coda.co/https-coda-payments.gitbook.io-zhong-wen-coda-private-technical-documentation/codashop-yu-distrubution/ji-cheng-zhi-nan/topup-api-qing-qiu.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
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.
