TikTok Shop OAuth2

Demonstrates how to get the initial OAuth2 access token for a TikTop Shop application. This is for desktop applications and scripts only. It is not for server-side code running on a web server. Go

    success := false

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

    oauth2 := chilkat.NewOAuth2()

    // This should be the port in the localhost callback URL for your app.  
    // The callback URL would look like "http://localhost:3017/" if the port number is 3017.
    oauth2.SetListenPort(3017)

    oauth2.SetAuthorizationEndpoint("https://services.tiktokshop.com/open/authorize")

    // Replace these with actual values.
    oauth2.SetClientId("APP_KEY")
    oauth2.SetClientSecret("APP_SECRET")

    oauth2.SetScope("")

    // See https://partner.tiktokshop.com/doc/page/63fd743c715d622a338c4e5a

    // Once you have the service_id, it should not change.
