The payload.json file contains payload to AdWords API.
As you can see "header" in payload is "Models". It is saved in the UI with language "Catalan" by default as there is no way to pass language through API and set that this is English(US), for instance.
So if there are same headers values for several languages - first in the list got's displayed in the UI. (Same for "Модели" header as well. It is always saved as Bulgarian, even if I want to save it as Russian).
So things got even more complicated when it comes to import or sync campaigns... As in the response from Adwords API (getEntityFromAdwordsAPI.json) we get only header with no mention about chosen language ... So how do we know that header "Models" is in English not Catalan?
Hope it helps to understand the issue.
Thank you!
