Hi @pavel.karpukhin ,
Thanks for the details! As far as I can see, the response is successful. However, in your request body, you have set the parameter “translateWithPerfectMatchOnly”:true, which means that only those strings that have a perfect match TM suggestion will receive the translation.
From my database, I can see that this file that you are applying pre-translation to has only 3 untranslated strings in French, for example, and none of them has a perfect match in the TM.
Thus, when running the Apply Pre-translation method, the response is successful, but there is nothing to apply. If you set the parameter “translateWithPerfectMatchOnly”:false, the translations will be applied when there are perfect match and not less than 100% match suggestions.
Hope this helps!
