In order to make their account access to meta APIs, Instagram users must first convert their account to a Professional account, create a Facebook Page that represents their business, then connect that Page to their account.
Business Login for Instagram simplifies this process by allowing Instagram users to complete all of these steps in a single window instead of having to complete them in the Facebook and Instagram apps.
When under the company profile page, there is a channels tab that the user can use to add a new Instagram channel.
