// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// See Get Wish OAuth2 Access Token 
// for sample code showing how to obtain a Wish access token for desktop apps.

// This example assumes we previously obtained an OAuth2 access token for Wish.

// Note: In most OAuth2 implementations, the token endpoint is the same for both the
// refresh request and the exchange-code-for-token request (which happens when getting
// the OAuth2 token for the 1st time).   Wish uses a different URL for the refresh:
$oauth2->put_TokenEndpoint('https://merchant.wish.com/api/v3/oauth/refresh_token');

// The following uncommon option was added in Chilkat v9.5.0.85
