Language
Upsert (create or replace) a Language
Creates a Language if it does not yet exist (i.e. if the resource does not have an id property yet), or replaces the existing Language resource if it does. Note that this replaces the entire Language object. It is not just a partial update.

Headers
ifMatchstring
The If-Match header is used with PUT and DELETE requests to check whether you have the most up-to-date version of the resource before updating or deleting it. The value of the If-Match header is the ETag (_etag) property of the resource. It is recommended that your application use this header whenever possible to avoid data conflicts.
