How to track clicks on social buttons?

Question

Social media

It is important for me that the user shared the link, for example, to give the user goodies. I'm interested in vk. I was in the VK API, posted it, but there was no callback, but I also want to know what the user shared. Is this even possible? And which side to look?

Answer 1

When you just share a link, there is no callback, but you can get a callback if you share with friends through the like button.
