Intento Translate API supports Naver Papago NMT API.
In order to try it in SDL Trados please select Naver Papago NMT API from the list of available engines. Please note that Naver Papago NMT API works in a very limited demo mode.
For production usage, you should use your own credentials. Please obtain credentials from Naver and add them to Connected Accounts in Console (this is how) and then select Naver Papago NMT Commercial from the list.
