(CkPython) Ecwid Get OAuth2 Access Token

See more Ecwid Examples

Demonstrates how to get an OAuth2 access token for an Ecwid application.

IMPORTANT: This example is for desktop apps. Web applications should follow representative examples at ASP.NET Samples for Obtaining OAuth2 Access Tokens or at Classic ASP Samples for Obtaining OAuth2 Access Tokens

Please read about Ecwid Authentication Basics prior to attempting this example.

For more information, see https://api-docs.ecwid.com/reference/get-access-token#get-token-manually
