## 选择集成路线

开始集成前，先选择一条路径。两条路径最终都需要完成沙盒测试，并将验收材料提交给 Waffo 技术对接群确认。

### API integration

适合已有自建收银台、需要完全控制服务端支付流程，或希望按 API Reference 手工接入的团队。

<Steps>
  <Step title="选择产品方案">
    一次性支付适合单次收款订单；订阅支付适合周期扣款场景。
  </Step>

  <Step title="接入必需 API">
    按 [API 直连](/docs/zh/developer-docs/integration/api/overview) 路线图接入必需接口。
  </Step>

  <Step title="查看 API Reference 细节">
    在 [API Reference](/docs/api-reference/introduction) 查看字段、请求、响应和签名细节。
  </Step>

  <Step title="完成额外支付配置">
    如需 Apple Pay 或 Google Pay，完成 [沙盒与测试](/docs/zh/developer-docs/getting-started/sandbox) 中的额外测试和配置。
  </Step>

  <Step title="提交验收结果">
    在沙盒环境完成测试，下载并填写验收用例模板，然后将验收结果提交给 Waffo 技术对接群。
  </Step>
</Steps>

### AI integration tool

适合希望让 AI 编码工具自动生成 SDK 接入代码、测试代码和测试报告的团队。

<Steps>
  <Step title="安装 waffo-integrate">
    运行 `npx @waffo/waffo-integrate`。
  </Step>

  <Step title="触发集成">
    在 Claude Code 或 Cursor 中触发 Waffo 集成。
  </Step>

  <Step title="回答业务问题">
    回答 AI 提出的业务问题，例如产品类型、退款、订阅、Webhook 是否需要接入。
  </Step>

  <Step title="审核代码和测试报告">
    AI 会生成代码、运行集成测试，并输出测试报告。
  </Step>

  <Step title="提交测试报告">
    将测试报告提交给 Waffo 技术对接群确认。
  </Step>
</Steps>

## 推荐：使用 AI 集成工具（waffo-integrate）

**waffo-integrate** 是 Waffo 官方的 AI 集成 Skill，通过交互式向导自动生成生产级代码，比手动集成快 33%，成功率 100%。

### 安装

<CodeGroup>
  ```bash 自动检测（推荐） theme={null}
  npx @waffo/waffo-integrate
  ```

  ```bash Claude Code theme={null}
  npx @waffo/waffo-integrate --claude
  ```

  ```bash Cursor theme={null}
  npx @waffo/waffo-integrate --cursor
  ```
</CodeGroup>

### 使用

安装后在 AI 助手中触发即可：

* 输入 `integrate waffo` 或 `接入waffo`
* Skill 会引导你完成：选择功能（支付/退款/订阅/Webhook）→ 检测语言 → 生成代码 → 运行验证测试

### 支持的语言和功能

| 语言      | SDK                             | 框架                       |
| ------- | ------------------------------- | ------------------------ |
| Node.js | `@waffo/waffo-node`             | Express, NestJS, Fastify |
| Java    | `com.waffo:waffo-java`          | Spring Boot              |
| Go      | `github.com/waffo-com/waffo-go` | Gin, Echo, Fiber, Chi    |

所有功能均可通过 Skill 自动集成：支付、退款、订阅（含升降级）、Webhook、商户配置查询、支付方式查询。

### 优势

| 指标             | 使用 Skill           | 手动集成       |
| -------------- | ------------------ | ---------- |
| 通过率            | **100%**（16/16 断言） | 75%（12/16） |
| 集成时间           | 约 128 秒            | 约 192 秒    |
| 内置 13 条 API 规则 | 自动防错（字段名、枚举值、必填项）  | 需要自行查阅文档   |

## 手动集成

如果不使用 AI 工具，可以按以下步骤手动集成。

## 前置条件

* Waffo 商户账号
* API Key（从 Dashboard 获取）
* RSA 密钥对（参见 [认证与签名](/docs/zh/developer-docs/integration/api/overview)）
