How to create a Discord bot in C++ 98 with platform toolset version v120?

I'm working on a C++ 98 project with platform toolset version v120 on VS 2013. I'm trying to implement Discord bot API in my project. I've tried several unofficial Discord libraries for C++, like Sleepy-Discord, DPP, and Discord.CPP. But it seems like none of them are compatible with my project's C++/platform toolset version. Unfortunately, I cannot update my project as it's too big. I want to know if there's any solution for this.

What I'm expecting:

A Discord lib for CPP compatible with my project's PTV v120.
Or a way to downgrade one of the Discord libraries to make it compatible with my project.
Or a way to interact with the Discord API through my project.
Any other way.

Thank you.

As stated on the Discord Developer Portal, their API can be accessed entirely through web requests. You don't need any additional libraries, except if you want to use a prebuilt REST or WebSocket library for easier use, which - if available to you - i would highly recommend.
