(Tcl) TikTok Shop OAuth2

See more TikTok Shop Examples

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.

IMPORTANT: This example requires a pre-release for the next version of Chilkat after the current v9.5.0.99 release. Contact info@chilkatsoft.com if you wish to get a pre-release. However, pre-releases of .NET Core (hosted on NuGet) and Node.js will not be possible.
