Instagram — Policy Change

majorPro-PrivacySep 1, 2017 → Apr 4, 2018Policy Change

Executive Summary

In the wake of the Cambridge Analytica scandal, Instagram deprecated its legacy Platform API and dramatically restricted third-party access to user data. Apps were limited to basic profile information and user-owned media only, eliminating the ability to access followers' data or public content at scale. The changes mirrored Facebook's broader platform lockdown.

What Happened

On April 4, 2018, Instagram immediately shut down parts of its legacy Platform API that were originally scheduled for deprecation on July 31, 2018, as part of Facebook's response to the Cambridge Analytica scandal. The APIs for follower lists, relationships, and commenting on public content ceased functioning immediately, while rate limits were reduced on other APIs scheduled for later deprecation. Instagram moved third-party apps to the new Instagram Graph API, which restricted access to basic profile information and user-owned media only for business profiles, eliminating broader access to public content and follower data.

Who Is Affected

Third-party app developers who built tools using Instagram's legacy API lost immediate access to follower data, relationship features, and public content commenting capabilities. Users of these third-party apps, particularly those that analyzed followers or helped grow audiences, found their applications stopped working over the weekend before the announcement. Instagram business profile owners could continue using limited features through the new Graph API, while support for non-business profiles was promised for early 2019.

Why It Matters

This represented a dramatic shift in Instagram's approach to third-party data access, moving from an open platform model to a highly restricted one in response to privacy concerns raised by the Cambridge Analytica scandal. Facebook's CTO stated the company would not take chances around data privacy and acknowledged that most people on Facebook could have had their public profile scraped by malicious actors. The sudden implementation, ahead of the announced timeline and without prior notice to developers, demonstrated the urgency with which Facebook addressed platform-wide data access in the wake of discovering up to 87 million users had their data improperly obtained.

What You Should Do

If you use third-party Instagram apps that analyze followers or manage your account, check whether they still function properly and review what data permissions you have granted them. Review and remove apps you no longer use or trust by checking your connected applications in Instagram's settings. If you operate an Instagram business profile and rely on third-party tools, migrate to apps that use the new Instagram Graph API to ensure continued functionality.
