Question

Good day, friends!
Interested in the next one. There is a site. Entrance to it is possible only through social networks. A profile is created on the site based on information from the VK profile. Is it possible to pull a list of friends from VK and see which other friends in VK have a profile on my site?
In other words: you and I are friends on VK. I also have an account on my website. Can I find out if you have an account on my site through VK?
Thanks in advance!
