Extract all response headers from an API call, store them in a headers object, and use header names with get value to retrieve specific values for validation or reuse.

Learn to extract all response cookies, store them in a string-to-string map, retrieve values by name, and reuse them for validation or in subsequent API requests, like header extraction.

Explore basic and digest authentication using username and password; basic encodes with base 64 encoding, digest uses hash encryption, and learn about preemptive and challenged authentication with rest assured.

Update the pom.xml by adding the ScribeJava API dependency (groupId com.github.scribejava, artifactId scibejava.apis, version 2.5.2) and upgrade Rest Assured to 3.1.0, then refresh the Maven project.

Understand OAuth 1.0, its keys and tokens: API key, API secret key, access token, and access token secret, and how to set up a Twitter developer app to post tweets.

learn how to post a tweet with rest assured using twitter oauth1.0, including api key, api secret, access token, and base uri, then validate the response.
