You can’t use API keys from DeepL, Google, or Microsoft, because WPML doesn’t support this functionality.
WPML Automatic Translation vs API Key
All costs considered, using your own API key can be more expensive. This is because WPML includes several features that reduce cost when it comes to automatic translation:
- Translation memory – avoid paying twice for content you already translated, and automatically fill-in saved translations.
- Glossary – save credits by indicating translations for specific terms and phrases.
- Free credits on purchase – enjoy up to 180,000 free credits (~$55) when purchasing WPML.
- Free monthly credits – enjoy 2,000 free credits every month when using pay-as-you-go.
- Hosted servers – avoid overloading your own servers (and paying more) by offsetting translation processes to WPML’s private servers.
