HubSpot workflow custom code runs server-side, so it can’t open a browser window for Xero’s login.To handle Xero’s OAuth 2.0 login, you need to trigger the login flow from a client-side app or page, not from the server code. Instead, redirect the user to a custom HubSpot landing page that includes a button linking to the Xero auth URL. Once the user logs in and selects their org, Xero redirects to your redirect URI with a code.Set up a backend (e.g., serverless function) to exchange that code for tokens .Then store the access and refresh tokens in HubSpot using custom properties or a secure storage.Call Xero APIs later from workflow custom code using those stored tokens.
