VK

In VK the bot replies in community messages. There is no token to enter: you sign in with VK and choose a community from the list.

What you need

A VK community that you manage.

In the bot's scheme, click "Connect messenger" and choose "VK".
A VK window opens. Sign in to your account and allow access.
In the list of communities, mark the one the bot will reply from and click "Save".

The platform turns on community messages and the other settings on the VK side by itself.

After connecting, the window shows the link to the conversation with the community and a QR code.

Tip

The VK window opens as a pop-up. If nothing happens after you choose "VK", allow pop-ups for the site in your browser settings.

Buttons — under a message and under the input field, link buttons, coloured buttons.
The phone is typed by the person: VK has no separate phone request button, so the bot asks for the number in a message.
Mailings are available. A mailing gets a message type according to VK rules — promotional, informational and others; the platform's limit is shown next to each type.
Mini apps do not open inside VK. You can send the person a link — the app opens in the browser.

"No groups found". The account you signed in with does not manage any communities. Sign in with the community administrator's account.
You need another community. Disconnect the channel with the "Delete" button and connect it again, choosing the right one.
