DeepL Translate

This Action uses the DeepL API to translate the text in the current draft to the specified target language. You can configure it to either append the translated text to the draft or replace the current content.
You need to register for a free account of the DeepL API to make use of this action. Copy the generated API Key and insert it into the Prompt for the API credential when you run this Action the first time.


As mentioned, when you run this Action the first time, it will ask for an API Key of the DeepL API. Please copy and paste your key into that prompt. It will be stored in Drafts credentials - if you run into issues with the API you can „forget“ the credential in Drafts Settings

You need to set the target language (the language you want your draft to be translated to). By default this is EN but you can change that to one of the options below. Please only insert the two letter language code into the „Define Template Tag“ step for target_language

Following options are available as target language:

  • BG - Bulgarian
  • CS - Czech
  • DA - Danish
  • DE - German
  • EL - Greek
  • EN - English (unspecified variant for backward compatibility; please select EN-GB or EN-USinstead)
  • EN-GB - English (British)
  • EN-US - English (American)
  • ES - Spanish
  • ET - Estonian
  • FI - Finnish
  • FR - French
  • HU - Hungarian
  • ID - Indonesian
  • IT - Italian
  • JA - Japanese
  • KO - Korean
  • LT - Lithuanian
  • LV - Latvian
  • NB - Norwegian (Bokmål)
  • NL - Dutch
  • PL - Polish
  • PT - Portuguese (unspecified variant for backward compatibility; please select PT-BR or PT-PT instead)
  • PT-BR - Portuguese (Brazilian)
  • PT-PT - Portuguese (all Portuguese varieties excluding Brazilian Portuguese)
  • RO - Romanian
  • RU - Russian
  • SK - Slovak
  • SL - Slovenian
  • SV - Swedish
  • TR - Turkish
  • UK - Ukrainian
  • ZH - Chinese (simplified)

You can always check an up-to-date list in the DeepL API reference

By default the Action will append the translation to the current draft. If you want the Action to replace the current content of the draft with the translated text you can change the Template tag result_insert_mode to replace. Please note: only append and replace are valid values for this template tag. If you use something else, it will default to appending the text
