The script is ready to pull data from your group and page.I only need to configure it correctly in the app settings. As i like to work based on progress i would like to get milestone payment. Can you please send 100$ to my paypal account?My paypal account is: ariful0198@gmail.com

I will ask for the rest after integrating it fully in your website.

The reason i am asking you this way is i don't like to get payment on fiverr because it takes 20% of the earning.  Fiverr also prohibits outside communication and payment so i have to let you know this way here. Hope its okay for you. Here are the info for a quick communication with me.
