You can conditionally retrieve only the changed settings and connections metadata.
To retrieve the changed application settings information:
http[s]://<host:port>/[public/]odata/applications/{latest|v1}/{appID}/Connections(‘{appcid}’)?If-None-Match=”${ETag}”
The ${ETag} part of the URL is a version identifier included in the response of the GET method. If the ETag value of the current application settings is the same as the value included in the request, a status code 304 without a response body is returned to the client to indicate that there are no application setting changes.

To retrieve the service document of the SAP Mobile Platform Server:
