# 审批实例状态变更 审批实例状态发生变更时会触发该事件。状态变更包括： - 用户创建审批后，触发该事件并推送 PENDING（审批中）状态。 - 审批实例内，任一审批人拒绝审批任务后，触发该事件并推送 REJECTED（已拒绝）状态。 - 审批实例内，所有审批任务均同意后，触发该事件并推送 APPROVED（已通过）状态。 - 发起人撤回审批后，推送 CANCELED（已撤回）状态。 - 审批定义下存在审批中的审批实例时，若该审批定义被管理员删除，则触发该事件并推送 DELETED（已删除）状态。 - 发起人撤销已通过的审批时，触发该事件并推送 REVERTED（已撤销）状态（该方式触发的事件中的 `operate_time` 字段数据类型为 int64，而不是字符串）。 - 审批实例超时未处理被关闭，触发该事件并推送 OVERTIME_CLOSE（超时被关闭）状态。 - 已超时的审批实例被手动恢复，触发该事件并推送 OVERTIME_RECOVER（超时实例被恢复）状态。 ## 前提条件 - 应用已配置事件订阅，了解事件订阅可参见[事件订阅概述](https://open.feishu.cn/document/ukTMukTMukTM/uUTNz4SN1MjL1UzM)。 - 应用已调用[订阅审批事件](https://open.feishu.cn/document/uAjLw4CM/ukTMukTMukTM/reference/approval-v4/approval/subscribe)接口，订阅了审批实例对应的审批定义 Code。 ## 事件 基本 |   ---|--- 事件类型 | approval_instance 支持的应用类型 | Custom App、Store App 权限要求
**订阅该事件所需的权限，开启其中任意一项权限即可订阅**
开启任一权限即可 | 访问审批应用(approval:approval:readonly)
查看、创建、更新、删除审批应用相关信息(approval:approval) 推送方式 | [Webhook](https://open.feishu.cn/document/ukTMukTMukTM/uUTNz4SN1MjL1UzM) ## 事件体 字段 | 数据类型 | 描述 ---|---|--- ts | string | 事件发送时间。包含小数的秒级时间戳。 uuid | string | 事件的唯一标识。 token | string | 事件 Token，即应用的 Verification Token。 type | string | 固定取值 `event_callback`。 event | object | 事件详细信息。 app_id | string | 应用的 App ID。可调用[获取应用信息](https://open.feishu.cn/document/uAjLw4CM/ukTMukTMukTM/application-v6/application/get)接口查询应用详细信息。 tenant_key | string | 企业唯一标识。 type | string | 事件类型。固定取值 `approval_instance` approval_code | string | 审批定义 Code。可调用[查看指定审批定义](https://open.feishu.cn/document/uAjLw4CM/ukTMukTMukTM/reference/approval-v4/approval/get)接口查询审批定义详情。 instance_code | string | 审批实例 Code。可调用[获取单个审批实例详情](https://open.feishu.cn/document/uAjLw4CM/ukTMukTMukTM/reference/approval-v4/instance/get)接口查询审批实例详情。 status | string | 审批实例状态。可能值有：
- PENDING：审批中
- APPROVED：已通过
- REJECTED：已拒绝
- CANCELED：已撤回
- DELETED：已删除
- REVERTED：已撤销
- OVERTIME_CLOSE：超时被关闭
- OVERTIME_RECOVER：超时实例被恢复 operate_time | string | 事件发生时间，毫秒级时间戳。
**注意**：当发起人撤销已通过的审批，推送 `REVERTED` 状态时，该该字段数据类型为 int64，而不是 string。 instance_operate_time | string | 事件发生事件，毫秒级时间戳。 uuid | string | 如果[创建审批实例](https://open.feishu.cn/document/uAjLw4CM/ukTMukTMukTM/reference/approval-v4/instance/create)时传入了 uuid，则此处返回该实例的 uuid。 ## 事件体示例 ```json { "ts": "1502199207.7171419", "uuid": "bc447199585340d1f3728d26b1c0297a", "token": "41a9425ea7df4536a7623e38fa321bae", "type": "event_callback", "event": { "app_id": "cli_xxx", "tenant_key":"xxx", "type": "approval_instance", "approval_code": "7C468A54-8745-2245-9675-08B7C63E7A85", "instance_code": "81D31358-93AF-92D6-7425-01A5D67C4E71", "status": "PENDING", "operate_time": "1666079207003", "instance_operate_time": "1666079207003", "uuid":"6525bffb" } } ``` ### 事件订阅示例代码 事件订阅流程可参考：[事件订阅概述](https://open.feishu.cn/document/ukTMukTMukTM/uUTNz4SN1MjL1UzM)，新手入门可参考：[教程](https://open.feishu.cn/document/uAjLw4CM/uMzNwEjLzcDMx4yM3ATM/develop-an-echo-bot/introduction) ** package main import ( "context" "fmt" larkcore "github.com/larksuite/oapi-sdk-go/v3/core" larkevent "github.com/larksuite/oapi-sdk-go/v3/event" "github.com/larksuite/oapi-sdk-go/v3/event/dispatcher" "github.com/larksuite/oapi-sdk-go/v3/service/approval/old" larkws "github.com/larksuite/oapi-sdk-go/v3/ws" ) // SDK 使用说明 SDK user guide：https://open.feishu.cn/document/uAjLw4CM/ukTMukTMukTM/server-side-sdk/golang-sdk-guide/preparations func main() { // 注册事件 Register event eventHandler := dispatcher.NewEventDispatcher("", "").
