(PowerShell) Twitter PIN-Based Authorization (Step 1)

Demonstrates the 1st step in Twitter PIN-based authorization using OAuth. The purpose of this step is to obtain a temporary request token that will be traded for an access token + secret in the final step. Once the access token + secret is obtained, the application can access the Twitter account in whatever ways it was authorized.

Note: This example requires Chilkat v11.0.0 or greater.

    # At this point, the end-user needs to browse to the following
    # Twitter URL to log in to his/her Twitter account and get a PIN.
    # 
    # https://api.twitter.com/oauth/authenticate?oauth_token=OAUTH_TOKEN
    # 
    # (where OAUTH_TOKEN is replaced with the contents
    # of the OAuth temporary request token.)

    # Your application may have an embedded browser such
    # that it automatically navigates to the above URL, or it may
    # be necessary for the user to browse to this URL independently.

    # Once the PIN is obtained, your application should provide a means
    # for the end-user to enter it (by typing it into an input text box, for example), 
    # and then Step 2 (the final step) can begin.
