I've spend some hours to understand that the request for translation with Ex-Bing (Microsoft Translator) API was deprecated with appId parameters on GET mode.
Now, we need of a registered application on Microsoft MarketPlace, and then we need of client ID and client Secret, in order to use translations (for 2 milions of characters per month!).
Then, we can request an access token for use Translation. I've applied some editing for get client ID and client Secret, but we need of POST mode instead of GET mode.
Anyway, I've some issue during request.
Because Google does not have more free translation available, I think that Microsoft Translation API is the free solution.
Someone can help me on resolve this issue?
