How to get authorized on the site and then add a task using the VkMIx API and C#?

Question

API

Hello everyone, I’ll say in advance that I’m a noob in the field of programming, and that’s why I came here XD
And so, what needs to be done:
1. Log in to the site using api_token
2. Add a new task on the site
and that’s it :)
Here are photos of working with the API
