List offer from file in English

[Artudatech]

Hello, I am trying to list some offers. But the title and description of the offers are all written in English. I wonder if I can just put them in the file, or do I need to translate them into Polish before listing? 

Thank you in advance. Good day.

@Artudatech If you post an offer via API, you can choose the language in which you want to create it. If you list your offer in English, we will automatically translate it into Polish for buyers who have set this language on their account.
