如何成为Instagram中任何客户的Instagram沙盒用户

我正在使用Instagram登录构建应用程序。我能够根据沙箱速率限制登录并获取20个媒体文件。现在，由于我想要获取标记图像，我必须邀请用户访问沙箱，之后我可以标记他们的照片并获取数据。

I am building an application with Instagram login. I was able to login and fetch 20 media files as per sandbox rate-limits. Now since I want to fetch the tagged images, I have to invite users to the sandbox after which I can tag their photos and fetch data.

我的问题在于我是无法发送沙盒邀请。

My problem here is I am not able to send sandbox invite.

我转到管理客户端>编辑>沙箱选项>输入用户名 ，进入邀请。
在沙盒用户中显示为未保存，并且我向其发送邀请的人未获得任何邀请。

I go to Manage Client > edit > sandbox option > type user name, enter to invite. It appears as NOT SAVED in sandbox user, and the person to whom I am sending the invite is not getting any invite.

请帮助我，因为这是我在Instagram上的第一个项目。

Kindly help me as this is my first project on Instagram.
