Enable origins allowed list for CORS in webex
Admins are given the ability to set up an email list that will allow cross-origin sharing of resources (CORS). It is possible to access meeting data for the domains listed in the allowed list by using the XML API. CORS configuration was required to be configured by the TAC when earlier versions of Webex meeting services were available.
