Hello,
I can make the integration of the instagram api with your system api. As per the information given I understood that I need the php code to login into instagram through its api, then the code needs to fetch required data from instagram with the same login cookies/session, and then the data needs to be displayed through the php code.
I am fully capable of integrating other apis into php code.
Do let me know if you are interested, I can start work on project right now.
Thank you
