Sometimes I get totally confused like why you use a get command when you’re trying to put something?

That is just a style choice by developers. A webserver can abitrarily choose how it wants to react to a GET request like http://mysite.com/data=xyz.

But if this confuses you, that’s actually very good, because it shows that it goes against your gut instincts to upload / create a new data point with a GET request and not using one of the other HTTP methods / verbs, like POST and PUT. The RESTful design philosophy for creating Web APIs states how the verbs should be used – GET to retrieve a resources/ information, POST to create a new one, PUT to update, etc.

And in fact the above first link says that the URL supports both GET and POST methods.

HTTP Method

POST or GET
…
Content-Type

Content-Type is required only for the POST method, not for the GET method.

application/x-www-form-urlencoded for most updates.

application/json for updates in JSON format.

…So, they kinda follow the RESTful design philosophy, by accepting both POST and GET requests.
