origin

When accessing the API using a cross-domain AJAX request (CORS), set this to the originating domain. This must be included in any pre-flight request, and therefore must be part of the request URI (not the POST body). For authenticated requests, this must match one of the origins in the Origin header exactly, so it has to be set to something like https://en.wikipedia.org or https://meta.wikimedia.org . If this parameter does not match the Origin header, a 403 response will be returned. If this parameter matches the Origin header and the origin is whitelisted, the Access-Control-Allow-Origin and Access-Control-Allow-Credentials headers will be set. For non-authenticated requests, specify the value * . This will cause the Access-Control-Allow-Origin header to be set, but Access-Control-Allow-Credentials will be false and all user-specific data will be restricted.
