# 集成后
1. 原有新商户**我可以在哪里配置订单（回调和重定向）URL？**
* 沙盒环境的 URL 可以在 Coda后台 -> 集成 -> Codapay -> 沙盒配置中进行配置。
* 正式环境的配置可以在 Coda后台 -> 集成 -> Codapay -> Production Transaction URLs 中进行。
***

前往 Coda后台 -> 集成 -> Codapay -> API Keys -> 编辑，输入 IP 地址。

4. **我在生产环境中请求Codapay 接口时遇到了 205 错误，我该怎么办？**
当商户的沙盒系统指向 Coda 的生产系统，但 Coda 正式环境中的状态仍设置为“测试”时，会出现此错误。在这种情况下，商户应将其 airtime URL 切换到沙盒 URL 以继续测试。 \
\
此外，如果商户的系统正确指向 Coda 的正式环境，但商户账户尚未在 Coda 的生产环境中激活，也会发生此错误。此时，商户应联系 Codapay 技术支持团队以激活其账户。
***
5. **我没有对应支付渠道的本地钱包/账户，Coda 是否提供任何测试账户信息，供我在生产环境中使用并测试完成支付？**
有的，但建议商户在使用真实货币进行测试之前，先在沙盒环境中完成测试，因为正式环境中的支付订单一旦完成，将**无法进行退款处理**。
在生产环境中的测试目的是确保回调能够成功发送。因此，商户只需要在每个国家选择 1 至 2 个支付渠道进行测试即可。
对于无法测试的支付渠道，商户应确保已正确配置，并且支付页面能够在正式环境中正常加载。

**如果商户需要 Coda 协助进行真钱测试:**
请： **提前 1 个工作日通**知 Coda 技术团队以分配资源和人力。\[周末不提供支持] \
Coda 技术团队的工作时间为**上午 9 点至下午 6 点（GMT +8）**

## 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/codapay/codapay-jie-ru-chang-jian-wen-ti/zhi-fu-ye-mian-api/ji-cheng-hou.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.
