How to make authorization on VK like SMMBox with permissions to the wall?

Question

PHP

There was a need to use posting on the wall through the VK api, I caught the eye of smmbox and tried to do it like they did, but niasilil.
On smmbox, authorization is used via a link like https://oauth.vk.com/authorize?client_id=APP_ID&re...
However, according to the docs and what I get, with this method, the rights to the wall are ignored, and work only if you specify redirect to the blank.html contact page and manually copy-paste the access_token from there. Of all the options, it works fine for me only through the JS API, but with a confirmation window.
So is this still possible, or does the smmbox application have some additional privileges that are inaccessible to mere mortals or require contacting some kind of support?

They have an agreement with VKontakte. Support will tell you everything in detail.
