What is the first step when a client application logs into the API?

When a client application logs into the API, the first step is for the client app to make the login() call. This is crucial because it is the initial request that initiates the authentication process. The login() call typically involves sending credentials, such as the username and password, to the API, which then processes these credentials to generate a session token or another form of authentication that allows the client account to access protected resources.

Making the login() call is fundamental as it establishes the communication between the client and the server, outlining the client’s intent to authenticate and gain access to the system. Only after this call is made can subsequent actions, such as retrieving the user profile or server URL, take place, thereby making it the appropriate first step in the authentication sequence.
