How to translate a text using Translate

Written by
Updated at November 2, 2024

To translate text, use the translate method.

Getting started

The Translate API requires you to send your authentication credentials in each request. The authentication method depends on the type of account used to send your request:

  1. Get an IAM token to authenticate your Yandex account or federated account. Transmit the token in the Authorization header of each request in the following format:

    Authorization: Bearer <IAM token>

  2. Get the ID of any folder for which your account has the ai.translate.user role or higher. Make sure to include your folder ID in the folderId field in the body of each request.

  1. Choose one of the authentication methods:

    • Get an IAM token. Include the IAM token in the Authorization header in the following format:

      Authorization: Bearer <IAM token>

    • Create an API key. Include the API key in the Authorization header in the following format:

      Authorization: Api-Key <API key>

  2. Assign the service account the ai.translate.user role or higher for the folder where it was created.

    Do not specify the folder ID in your requests, as YandexGPT uses the folder in which the service account was created.

Translating a text from any language

To translate a text from any supported language, provide it using the translate method:

To use the examples, install cURL.

The example below is intended to be run in MacOS and Linux. To run it in Windows, see how to work with Bash in Microsoft Windows.

This example shows how to translate two strings containing Hello and World into Russian. The text source language is recognized automatically.

  1. Create a file with the request body, e.g., body.json:

    {
    "folderId": "<Folder_ID>",
    "texts": ["Hello", "World"],
    "targetLanguageCode": "ru"
}

    Where:

  2. Submit the file for translation by running the command:

    export IAM_TOKEN=<IAM_token>
curl \
  --request POST \
  --header "Content-Type: application/json" \
  --header "Authorization: Bearer ${IAM_TOKEN}" \
  --data '@<path_to_JSON_file>' \
  "https://translate.api.cloud.yandex.net/translate/v2/translate"

    Where IAM_TOKEN is the IAM token received before starting.

    The service will return the translated strings:

    {
    "translations": [
        {
        "text": "Hello",
        "detectedLanguageCode": "en"
        },
        {
        "text": "World",
        "detectedLanguageCode": "en"
        }
    ]
}

This example shows how to translate the following two lines of text into Russian: Hello and World. The source language of a text is recognized automatically.

Create a file with the request body (for example, body.ру).

import requests

IAM_TOKEN = '<IAM_token>'
folder_id = '<folder_ID>'
target_language = 'ru'
texts = ["Hello", "World"]

body = {
    "targetLanguageCode": target_language,
    "texts": texts,
    "folderId": folder_id,
}

headers = {
    "Content-Type": "application/json",
    "Authorization": "Bearer {0}".format(IAM_TOKEN)
}

response = requests.post('https://translate.api.cloud.yandex.net/translate/v2/translate',
    json = body,
    headers = headers
)

print(response.text)

Where:

You can save your IAM token to a file. To do this, specify the file path in the token_path variable:

body.py
import os
import requests

token_path = '<path_to_file_with_IAM_token>'
folder_id = '<folder_ID>'
target_language = 'ru'
texts = ["Hello", "World"]
IAM_TOKEN = os.path.join(os.getcwd(), token_path)
with open(IAM_TOKEN) as f:
    IAM_TOKEN = f.read().strip()

body = {
    "targetLanguageCode": target_language,
    "texts": texts,
    "folderId": folder_id,
}

headers = {
    "Content-Type": "application/json",
    "Authorization": "Bearer {0}".format(IAM_TOKEN)
}

response = requests.post('https://translate.api.cloud.yandex.net/translate/v2/translate',
    json = body,
    headers = headers
)

print(response.text)

This example shows how to translate the following two lines of text into Russian: Hello and World. The source language of a text is recognized automatically.

Create a file with the request body, e.g., body.php:

<?php

$IAM_TOKEN = '<IAM_token>';
$folder_id = '<folder_ID>';
$target_language = 'ru';
$texts = ["Hello", "World"];

$url = 'https://translate.api.cloud.yandex.net/translate/v2/translate';

$headers = [
    'Content-Type: application/json',
    "Authorization: Bearer $IAM_TOKEN"
];

$post_data = [
    "targetLanguageCode" => $target_language,
    "texts" => $texts,
    "folderId" => $folder_id,
];

$data_json = json_encode($post_data);

$curl = curl_init();
curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
// curl_setopt($curl, CURLOPT_VERBOSE, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS, $data_json);
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_POST, true);

$result = curl_exec($curl);

curl_close($curl);

var_dump($result);

?>

Where:

You can save your IAM token to a file. To do this, specify the file path in the token_path variable:

body.php
<?php

$token_path = '<path_to_file_with_IAM_token>';
$folder_id = '<folder_ID>';
$target_language = 'ru';
$texts = ["Hello", "World"];

$IAM_TOKEN = trim(file_get_contents(realpath($token_path)));
$url = 'https://translate.api.cloud.yandex.net/translate/v2/translate';

$headers = [
    'Content-Type: application/json',
    "Authorization: Bearer $IAM_TOKEN"
];

$post_data = [

    "texts" => $texts,
    "folderId" => $folder_id,
];

$data_json = json_encode($post_data);

$curl = curl_init();
curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
// curl_setopt($curl, CURLOPT_VERBOSE, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS, $data_json);
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_POST, true);

$result = curl_exec($curl);

curl_close($curl);

var_dump($result);

?>
