Execute method returns str or list.

This is a list of dictionaries for each queried value. Each dictionary typically contains three keys (though not all will be present in all cases).

  • detectedSourceLanguage: The detected language (as an ISO 639-1 language code) of the text.

  • translatedText: The translation of the text into the target language.

  • input: The corresponding input value.

  • model: The model used to translate the text.

If only a single value is passed, then only a single dictionary is set as XCom return value.

  • values (str or list) – String or list of strings to translate.

  • target_language (str) – The language to translate results into. This is required by the API and defaults to the target language of the current instance.

  • format (str or None) – (Optional) One of text or html, to specify if the input text is plain text or HTML.

  • source_language (str or None) – (Optional) The language of the text to be translated.

  • model (str or None) – (Optional) The model used to translate the text, such as 'base' or 'nmt'.

  • impersonation_chain (Union[str, Sequence[str]]) – Optional service account to impersonate using short-term credentials, or chained list of accounts required to get the access_token of the last account in the list, which will be impersonated in the request. If set as a string, the account must grant the originating account the Service Account Token Creator IAM role. If set as a sequence, the identities from the list must grant Service Account Token Creator IAM role to the directly preceding identity, with first account from the list granting this role to the originating account (templated).
