Wish for Merchants -- Get OAuth2 Access Token for Desktop App

See more OAuth2 Examples

Demonstrates how to get a Wish for Merchants OAuth2 access token from a desktop application or script. Perl

use chilkat();

$success = 0;

#  To further clarify, see OAuth 2.0 Authorization Flow

#  This example is for desktop applicatons (it is not for code that runs on a web server).

#  This is the way to initially obtain the OAuth2 access token.  Afterwards it can be 
#  repeatedly refreshed without user interaction, as shown in this example: Refresh Wish OAuth2 Access Token.

$oauth2 = chilkat::CkOAuth2->new();

#  Wish OAuth2 does not allow a localhost callback URI such as "http://localhost:<portNumber>/"
#  For a desktop app, you must provide a script on your web server to redirect to "http://localhost/<portNumber>"

#  Your applicaton must use your own public web server as an intermediate
#  to receive and forward the redirect to localhost.
#  See Using Your Web Server as an Intermediary for OAuth2 Redirect to localhost

#  3: Success - OAuth2 flow completed, the background thread exited, and the successful response is in AccessTokenResponse.
#  4: Access Denied - OAuth2 flow completed, the background thread exited, and the error response is in AccessTokenResponse.
