On April 4th, 2018 Facebook announced a variety of API changes for both the Instagram and Facebook platform. These changes are mandatory. One of these changes is the retirement of the legacy Instagram API to be replaced with the Business Profiles API.
What needs to happen:
Convert to a Business Profile
You must convert your existing Instagram profile to a Business Profile. This should be completed as soon a possible. You may move your profile over to a Business profile now (as of May 25th) with no immediate consequences. These steps are to be completed:
Go to your profile and tap Settings.
Tap Switch to Business Profile.
Tap Switch to Business Profile and select the Facebook Page you'd like to associate with
your Business Profile on Instagram with.
Make sure your profile is set to Public. Private accounts can't switch to Business Accounts.
On the Set Up Your Business Profile page, review your business's contact information,
make any changes and tap Done.
Thank you for reading more on the new Instagram Business Profile Changes. If you have any additional questions, please reach out to your Account Manager or feel free to email firstname.lastname@example.org!
