The Microsoft AJAX Translation WordPress plugin offers a “Translate” button that allows readers to translate your blog’s posts into a specified language with a quick, light ajax call to the Microsoft Translator API.

Why Microsoft AJAX Translation?

As of December 1, 2011, Google Translate API v1 is no longer available; it was officially deprecated due to the substantial economic burden. Google Translate API v2 is now available as a paid service only, and the number of requests your application can make per day is limited.

This is dramatic news. All of those “free” programs that hitchhiked on Google Translate are history. A lot of wordpress plugins that depended on the free Google Translation Engine also not work any more.

Fortunately, Microsoft still provide a free translation API for programmer. That’s why I decide to develop this plugin, which uses Microsoft Translator API. It is a surprisingly adequate substitute for Google Translate.

Frequently Asked Questions

Why an AppID is needed?

In order to avoid extensive abuse, Microsoft requires you to include a valid API key when you make programmatic calls to the translation APIs.

How can I get an AppID?

It is free and takes only two minutes.

1. Go to, then click “Create your AppID”.
2. Sign up with your Windows Live ID.
3. Click “Get a new App ID”.
4. Fill in some basic info and submit.
5. Congratulations! You get your AppID, which is long string and you can use it in this plugin.

Can I customize the position of Translate button?

Yes. You can position the “Translate” button anywhere within the WordPress loop as shown below:

if( method_exists( $MicrosoftTranslation, 'microsoft_ajax_translate_button' ) ) {
	$MicrosoftTranslation -> microsoft_ajax_translate_button();

Can I translate the whole page?

Yes. Just click the “powered by bing” image on the translate popup, and your reader will get a full translated website.

Why is the quality of the translation not as good as I would like it to be?

You should understand that the translation your reader sees is raw machine translation. Currently, it still requires human skills to translate sentences without errors.

Translation not working?

  1. Have you filled in your AppID in the settings page?
  2. There are so many visitors requesting translation that Microsoft suspended your AppID.
  3. This plugin automatically uses the jQuery library supplied by your WordPress installation. If your theme or another plugin has another copy of jQuery hard coded into it this plugin may not work.
  4. Ask here or in the wordpress forums.
