title: How to be an Instagram sandbox user for any client in Instagram
body: <p>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.</p>
  
  <p>My problem here is I am not able to send sandbox invite.</p>
  
  <blockquote>
    <p>I go to <strong>Manage Client > edit > sandbox option > type user name</strong>, enter to invite.
    It appears as <strong>NOT SAVED</strong> in sandbox user, and the person to whom I am sending the invite is not getting any invite. </p>
  </blockquote>
  
  <p>Kindly help me as this is my first project on Instagram.</p>
