I have set up the facebook developers app and did all the configurations. even used webhooks and tested the API but i’m unable to read and send automated messages for my actual instagram account.
How to fix this? Am i missing out something, if anyone has done this before, please help me out.

I want to read messages from instagram and reply to it through my server.
i used the code template given by facebook for setting up the node js server.
