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. AutoIt

Local $bSuccess = False

;  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.

$oOauth2 = ObjCreate("Chilkat.OAuth2")

;  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

;  If the browser does not respond within the specified time, AuthFlowState will be:

;  In either case, cancel the background task initiated by StartAuth.

;  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.
;  5: Failure - OAuth2 flow failed before completion, the background thread exited, and error details are in FailureInfo.
