I am trying to get Xero to send a WebHook to Salesforce so we can capture updates to Contacts and Invoices.
I created an Unauthenticated RESTful web-service by exposing the RestResource annotated Apex Class to the Force.com Site Guest User.
But I am receiving back errors! Xero will not authorise an Endpoint unless it replies with an empty body and without cookies, however, Salesforce always returns back the BrowserId Cookie and I cannot work out how to remove this!
Does anyone have any ideas how to remove this? Or am I trying to find air in space?
