beast VS POCO

It appears that Google wrote some utilities to do this without manually having to deal with HTTP, but they are only available in Java, Python, Node.js, PHP and .NET - not C++. So you will have to write your own C++ library that sends HTTP requests to the web API and handles the received messages and data. You will need some library to handle network sockets and HTTP requests, such as libcurl or Boost Beast (or see under Communication here: https://en.cppreference.com/w/cpp/links/libs)

For example Boost-Beast and Boost-Mysql(not officially boost) receive user provided asio::io_context and every other library in this ecosystem should be the same.

Otherwise, Boost has an HTTP library: https://github.com/boostorg/beast

You can also look into Poco https://pocoproject.org/

I can't say enough good stuff about POCO for this type of work - when I first got my teams using it we used to joke that POCO was what Boost wants to be when it grows up. And nlohmann/json - cracking library for working with JSON in C++.

We use https://github.com/pocoproject/poco in most projects, very easy to set up a http listener

Did someone used Poco's Net Library to create a Rest Api? Poco Project

But CLion is so slow. Tested with Poco C++ standard build (https://pocoproject.org/). Moving around with Go To Definition takes sometimes up to 20 seconds if file is first touched. Using 'back' and 'forward' delays for 1-2 seconds.

Yes, you need NetSSL - take a look at find_package(Poco REQUIRED COMPONENTS ... NetSSL) requires an aditional find_package(OpenSSL) since poco-10.

Many of the necessary fixes do end up getting pushed upstream, though, thinking especially of stuff like converting CMake projects to use the GNUInstallDirs standard, so there is a benefit to the strictness work that extends beyond even just the Nix community itself.

Of course, sometimes those kinds of changes just never get merged, for a variety of well-understood open-sourcey reasons, eg: https://github.com/pocoproject/poco/pull/3105
