RESTful Web API Design with Node.js (Video 7)

The video tutorial covers the implementation of RESTful APIs and the use of Twitter's API for login flows. It explains OAuth 1.0a, detailing the authentication process and the roles of the client, server, and resource owner. A real-world example using Twitter demonstrates the OAuth flow, highlighting the steps to obtain access tokens and access user data securely.

What is the primary purpose of using Twitter's API in this tutorial?

• To create a new social media platform

• To implement a login flow and access user data

• To develop a new programming language

• To design a new database system

What does OAuth allow applications to do?

• Access user data without needing their password

• Create new user accounts automatically

• Delete user data from servers

• Send emails on behalf of users

Who are the three parties involved in the OAuth process?

• The client, the server, and the resource owner

• The developer, the user, and the database

• The browser, the operating system, and the hardware

• The application, the network, and the firewall

What is the first step in the OAuth authentication flow?

• Exchanging temporary credentials for an access token

• Redirecting the user to the server

• Asking for a request token

• Accessing the protected resources

In the OAuth process, what does the client do after receiving a request token?

• Deletes the token

• Redirects the user to the authentication URL

• Sends the token back to the server

• Stores the token in a database

What is the final step in the OAuth authentication flow?

• Logging out the user

• Exchanging temporary credentials for an access token

• Redirecting the user to the server

• Obtaining a request token

In the real-world example, what happens after signing in with Twitter?

• The application deletes the user's data

• The user is redirected to a different website

• The application exchanges the temporary credentials for an access token

• The user is logged out automatically
