## Q5: User Access Token failed to call OAPI

The User Access Token obtained by the Cloud Documents widget will only support calling the [Get Login User Information](https://open.feishu.cn/document/uAjLw4CM/ukTMukTMukTM/reference/authen-v1/authen/user_info) API to obtain user name and avatar information from February 2, 2024, and cannot call more OpenAPIs. ** If you need to use User Access Token to call OpenAPI, the business side needs to make relevant adaptations to ensure that the product functions are not affected.
