well Instagram says We will begin reviewing new and existing apps before granting full API access starting December 3, 2015. Existing apps have until June 1, 2016 to submit and be approved.

We are also launching Sandbox Mode, which will let you privately build and test your apps using Instagram’s APIs as your app is being reviewed. check this links for more help http://developers.instagram.com/post/133424514006/instagram-platform-update https://github.com/stevenschobert/instafeed.js/issues/345
