- Variables
source_document_url (str) – Location of the source document in the source container. Note that any SAS tokens are removed from this path.

Canceled - the operation was canceled, the document was not translated.
Canceling - the operation is canceling, the document will not be translated.
translated_to (str) – The language code of the language the document was translated to, if successful.
error (DocumentTranslationError) – Returned if there is an error with the particular document. Includes error code, message, target.
translation_progress (float) – Progress of the translation if available. Value is between [0.0, 1.0].

- class
azure.ai.translation.document.DocumentTranslationApiVersion(value)[source]¶ Document Translation API versions supported by this package
V1_0= '1.0'¶This is the default version
- class
azure.ai.translation.document.DocumentTranslationClient(endpoint: str, credential: Union[azure.core.credentials.AzureKeyCredential,TokenCredential], **kwargs: Any)[source]¶ DocumentTranslationClient is your interface to the Document Translation service. Use the client to translate whole documents while preserving source document structure and text formatting.
- Parameters
endpoint (str) – Supported Document Translation endpoint (protocol and hostname, for example:https://<resource-name>.).
credential (
AzureKeyCredentialorTokenCredential) – Credentials needed for the client to connect to Azure. This is an instance of AzureKeyCredential if using an API key or a token credential fromazure.identity.
- Keyword Arguments
api_version (str or DocumentTranslationApiVersion) – The API version of the service to use for requests. It defaults to the latest service version. Setting to an older version may result in reduced feature compatibility.
Example:
Creating the DocumentTranslationClient with an endpoint and API key.¶from azure.core.credentials import AzureKeyCredentialfrom azure.ai.translation.document import DocumentTranslationClientendpoint = os.environ["AZURE_DOCUMENT_TRANSLATION_ENDPOINT"]key = os.environ["AZURE_DOCUMENT_TRANSLATION_KEY"]document_translation_client = DocumentTranslationClient(endpoint, AzureKeyCredential(key))

There are two ways to call this method:
1) To perform translation on documents from a single source container to a single target container, pass thesource_url, target_url, and target_language parameters including any optional keyword arguments.
2) To pass multiple inputs for translation (multiple sources or targets), pass the inputs parameter as a list of
DocumentTranslationInput.For supported languages and document formats, see the service documentation:
- Parameters
- Keyword Arguments
source_language (str) – Language code for the source documents. If none is specified, the source language will be auto-detected for each document.
prefix (str) – A case-sensitive prefix string to filter documents in the source path for translation. For example, when using a Azure storage blob Uri, use the prefix to restrict sub folders for translation.
suffix (str) – A case-sensitive suffix string to filter documents in the source path for translation. This is most often use for file extensions.
storage_type (str or StorageInputType) – Storage type of the input documents source string. Possible values include: “Folder”, “File”.
category_id (str) – Category / custom model ID for using custom translation.
glossaries (list[TranslationGlossary]) – Glossaries to apply to translation.
- Returns
An instance of a DocumentTranslationLROPoller. Call result() on the poller object to return a pageable of DocumentStatus. A DocumentStatus will be returned for each translation on a document.
