import { Configuration, EmailApi } from 'mudbase-sdk';

const configuration = new Configuration({
  basePath: 'https://cloud.mudbase.dev',
  apiKey: 'sk_live_mudbase_doc_Xk9mP2qR7vN4wL8jH3tY6uE',
  accessToken: 'eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiJ1c3JfbW9yZ2FuX2RlIiwiZW1haWwiOiJtb3JnYW4uY2hlbkBub3J0aHdpbmQuZGV2IiwiZXhwIjoxODI1MTI5NjAwfQ.doc_preview_sig',
});
// This endpoint accepts either credential — apiKey or accessToken alone is enough.

const email = new EmailApi(configuration);
