When you hear API and web client together you think REST, at least I do. This is because it is still one of the most popular architectural paradigms for building APIs.

In my case the problem is that when I focus on something I forgot about the world around me and then after some time the sound of boiling water in pipes immediately pulls me out of my work and in few seconds I’m in the basement trying to resolve issue in different ways and this isn’t a pleasant operation. Please notice that this situation is very dangerous because boiling water can damage pipes and in few minutes your home can be flooded and repair costs probably will be very high. Solution to my issue would be replacing the old furnace with new one that can automatically take care of temperature adjustments, but I have got much more cheaper and more interensting solution for this one.
