Hello,
Greetings of the day!!
I have been through your requirements and understood that you want to integrate social media feature in your existing app. I have worked with various social APIs like Facebook, Twitter, Instagram, Flickr, Tumblr.
Also, share the source code of the app so we can go through the coding standard that you have used in your app.
Awaiting an affirmative response from your end.
Warm Regards,
Hardeep
