 - 位置：`app/integrations/base.py`
 - 规范：业务 Job 禁止直接写 HTTP；必须通过 Client 访问外部系统（统一超时、重试、日志）。
 
+#### SeeyonClient（致远 OA）
+
+- 位置：`app/integrations/seeyon.py`
+- 认证方式：`POST /seeyon/rest/token` 获取 `id` 作为 token，并在业务请求 header 中携带 `token: <id>`（参考：[调用Rest接口](https://open.seeyoncloud.com/seeyonapi/781/)）。
+- 最小配置示例：
+  - `public_cfg`：
+
+```json
+{"base_url":"https://oa.example.com"}
+```
+
+  - `secret_cfg`（会被加密落库）：
+
+```json
+{"rest_user":"REST帐号","rest_password":"REST密码","loginName":"可选-模拟登录名"}
+```
+
+- token 失效处理：遇到 401 或响应包含 `Invalid token`，自动刷新 token 并重试一次。
+
+#### 示例插件：sync_oa_to_didi（仅演示 token 获取日志）
+
+- 插件 Job：`extensions/sync_oa_to_didi/job.py` 的 `SyncOAToDidiTokenJob`
+- 在 Admin 创建 Job 时可使用：
+  - `handler_path`: `extensions.sync_oa_to_didi.job:SyncOAToDidiTokenJob`
+  - `public_cfg`：
+
+```json
+{"base_url":"https://oa.example.com"}
+```
+
+  - `secret_cfg`（会被加密落库）：
+
+```json
+{"rest_user":"REST帐号","rest_password":"REST密码","loginName":"可选-模拟登录名"}
