The DeepL API requires a DeepL Pro Subscription and your API Key can be found in your DeepL
account settings.
Enter the following URL in your browser and change the value of the
auth_key parameter to your
API key:
https://api.deepl.com/v1/translate?auth_key=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx&text=Hello&target_lang=de
If everything is in order, you should see a German translation for the word "
Hello":
{"translations":[{"detected_source_language":"EN","text":"Hallo"}]}
If however you receive a
403 Authorization Failed message, please check that your API key is correct. You can also generate a new API key in your DeepL
account settings.
If you receive a different error, please see the link to the DeepL website in the
reference section for a full list of error messages and consider contacting DeepL support.
