What is an instagram graph API and how do I use it?

The Instagram graph API will be used to get and publish the media, by managing and replying to comments on social media as well as identifying different media that is closely associated with your brand. First you will have to select the right media where there have been posts where you have been mentioned on Instagram, find hashtagged media along with getting a basic idea about the metadata and certain metrics which you can find out about through Instagram Businesses and Creators.
