我和我的同事有一个 C# WPF 项目，它管理 Google Classroom 中的课程。
我们在 Google API 平台中创建项目。我们是该项目的所有者。
两者都有 OAuth 2.0 客户端 ID。 （但这并不重要）
我允许 Classroom API 的所有范围。
我是 Gsuite for Education 的域管理员。域中允许使用 Google Classroom API。
他可以登录并使用该程序，没有任何错误，各项功能都正常。
我不能，因为我收到错误 400，invalid_request 帐户受限。
我尝试使用 API Explorer，只有当我想获取谷歌课堂课程的主题列表时才会出现此错误。
