# 获取企业内部应用的accessToken

> 企业内部应用调用本接口可获取 access_token,在调用钉钉服务端 API 时用于身份鉴权以确保请求合法且具备相应权限。

企业内部应用调用本接口获取访问凭证（accessToken）。在调用钉钉服务端API时，需通过accessToken进行身份鉴权，以确保请求来源合法并具备相应权限。

## 接口调用说明

本接口适用于企业内部系统集成场景，用于获取调用钉钉开放能力所需的访问凭证。典型使用流程如下：

* 应用启动或首次调用API前，调用本接口获取accessToken。
* 将获取到的accessToken缓存至本地存储（如Redis、内存缓存等），避免重复请求。
* 后续所有依赖鉴权的API调用均携带该accessToken。
* 建议设置缓存过期时间略小于7200秒（例如7000秒），实现自动刷新机制，防止因时间偏差导致凭证失效。
* 注意避免在短时间内频繁调用本接口，否则可能触发频率限制策略，影响服务稳定性。

### 响应体

| 名称          | 类型     | 示例值                     | 描述                                                                                                                                                          |
| ----------- | ------ | ----------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------- |
| accessToken | String | fw8ef8we8f76e6f7s8dxxxx | 生成的accessToken。  **说明**  在使用accessToken时，请注意以下几点：   - 开发者应自行缓存accessToken，并根据应用维度进行区分存储，因为每个企业内部应用的accessToken相互独立。 - 不可频繁调用本接口获取凭证，建议结合缓存机制控制调用频次，防止被系统限流。 |
| expireIn    | Long   | 7200                    | accessToken的过期时间，单位秒。  **说明**  accessToken的有效期为7200秒（2小时），有效期内重复获取会返回相同结果并自动续期，过期后获取会返回新的accessToken。                                                       |
