How to use Bing Translation API?

Question

I am trying to use the Bing Translation API, but I am confused. There seems to be much possibilities (old and new ones) but I don\'t understand what I have to do.

Can so

Answer 1

Follow the links on http://api.microsofttranslator.com. The API takes an access token in the appid parameter. See the section "Obtaining an access token" in the documentation to learn how to get that token.

Answer 2

Feel free to use this instructions (if you're using php):

Define your keys

$apis['azure']['id'] = 123456789
$apis['azure']['key'] = 'abcde123456';

    } catch (Exception $e) {
        echo "Exception: " . $e->getMessage() . PHP_EOL;
    }
}

The calls

echo get_translate_single('horse', 'en', 'es'); //this will print 'caballo'

or

echo get_translate(array('horse', 'house'), 'en', 'es'); //this will print array('caballo', 'casa')

That's it, have fun and remember to follow the terms of service.

Answer 3

AppID is deprecated. How you need perform following steps:

1. Register you clientID, clientSecter in https://datamarket.azure.com
   
2. Then you code must getting access token for login BingTranslator API
   

Read more details instrustions on http://msdn.microsoft.com/en-us/library/dd576287.aspx

NB Microsoft Translator has been replaced by Bing Translate, which does not appear to have a readily-available API.
