You are building an application that:

Uses Azure Translator service to translate text.

The text comes from getTextToBeTranslated() .

The text can be in many languages.

Requirement: the content must remain within the Americas Azure geography.

Output: must translate text into a single language (English in this case).

Step 1 – Choosing the correct endpoint

The Translator service provides region-specific endpoints.

For Americas geography, you must use the North America (NAM) endpoint:

https: //api-nam.cognitive.microsofttranslator.com/translate

Other options like api-apc (Asia Pacific) or api-nam.../detect are incorrect because:

/detect is used to identify the source language, not translate.

/transliterate is for script conversion, not translation.

We need the /translate path.

Step 2 – Setting the correct query parameter

To specify the target language, you must use the to query string parameter. Example:

?t o=en

Options like from=en or suggestedFrom=en are not correct here, because:

The text can be in many languages → we don’t know the source language in advance.

Translator automatically detects the source if from is not specified.

We only need to define the target language.

Final Code Snippet (corrected)

var endpoint = " https://api-nam.cognitive.microsofttranslator.com/translate " ;

var apiKey = " YOUR_SUBSCRIPTION_KEY " ;

var text = getTextToBeTranslated();

var body = " [{ ' Text ' : ' " + text + " ' }] " ;

var client = new HttpClient();

client.DefaultRequestHeaders.Add( " Ocp-Apim-Subscription-Key " , apiKey);

var uri = endpoint + " ?to=en " ;

HttpResponseMessage response;

var content = new StringContent(body, Encoding.UTF8, " application/json " );

response = await client.PutAsync(uri, content);

Correct Answer

Endpoint: https://api-nam.cognitive.microsofttranslator.com/translate

URI: ?to=en
