Client-server architecture – the client is responsible for the user interface, and the server is responsible for the backend and data storage.

REST API (Representational state transfer) is an API that uses HTTP requests for communication with web services. You do not need to know the internal structure and features of the service, you just send a certain simple command and receive data in a predetermined format.

Given that we have the SSL context, we then create a object for sending HTTP requests to the server:Īt this point of time, we can then use the http.client. Once we had defined the variables, we create a ssl.SSLContext object and load the certificate chain with what we have from the server:
