Natural Language Support
For every request that the add-in makes to the REST service, Oracle Visual Builder Add-in for Excel automatically adds the accept-language header.
The value sent with the accept-language header is the add-in’s preferred language/culture code. By default, the preferred language follows Excel’s user interface language. You can change the add-in’s preferred language as described in Change the Add-in’s Language.
Each REST service determines how and whether it will react to the accept-language header.
