Use case

Stated here word for word as it is submitted in App Review.

VN Hub is a first-party operations system for the Vladimir Nikandrov brand, operated by Studio 1804 FZE LLC on that company’s own Instagram professional account. When a follower sends the keyword СИГНАЛ in a direct message, a reply to a story, or a comment under one of the account’s own posts, VN Hub replies in the same thread with the link that was asked for and moves the conversation into Telegram, carrying a tracking ID so any resulting purchase stays attached to the message that started it. The app sends no cold messages, serves no other account, and has no public sign-up.

How to test it

  1. 01

    Open the account

    Go to the Instagram professional account listed in the submission.

  2. 02

    Send the keyword

    Send СИГНАЛ as a direct message. A reply to a story or a comment under one of the account’s own posts works the same way.

  3. 03

    Watch the reply arrive

    Within a few seconds the same thread receives the workshop link. Nothing else is sent, and nothing is sent at all if the keyword is absent.

  4. 04

    Follow the link

    It opens the Telegram bot with a tracking ID attached. Any purchase made from there is attributed back to the original Instagram message.

  5. 05

    Stop it

    Reply STOP, or remove the app in Instagram settings. Automation halts immediately and the record is deleted within 30 days.
