You need standalone vk app_id. You can use any app_id from https://vk.com/apps?act=wingames, for example 4775211 (Or you can create own app and get app_id on page https://vk.com/editapp?act=create (standalone app))
You can get token from you server ip with this node.js package: https://www.npmjs.com/package/vk-auth (you need login, pass and app_id)
To manual get token you need:
- Open in browser with logged in VK (you must use IP, where you want run bot)
https://oauth.vk.com/authorize?client_id={{app_id}}&scope=offline,groups,messages,friends&display=page&response_type=token&redirect_uri=https://oauth.vk.com/blank.html
- Copy token query parameter from URL string. Token valid only for IP from what you get it.
If you receive validation check (for example, you use ip first time)
{"error":{"error_code":17,"error_msg":"Validation required: please open redirect_uri in browser ...",
"redirect_uri":"https://m.vk.com/login?act=security_check&api_hash=Qwerty1234567890"}}you can use https://github.com/Yashko/vk-validation-node.
