Question

In contact with

There is a bot in VK and I want to add the creation of a referral link to it.
Example - vk. me/{group_name}?ref={ref}&ref_source={ref_source}
And how can I get data from it.
Thanks in advance.

Answer 1

You can make a substitution page.
That is, the link is not VK.ME, but some of your yurl, and you sew the correct link into the yurl, the client follows it, you read information about the client, and send it back via the wired link. Where exactly from which group, etc., it is impossible to track
