Install and activate this plugin alongside Loco Translate 2. Add your Langbly API key to wp-config.php 3. Select “Langbly” as your translation provider in Loco Translate 4. Click “Auto-translate” in the Loco editor. Done! #### Supported Languages Langbly supports all major languages including English, Dutch, German, French, Spanish, Portuguese, Italian, Chinese, Japanese, Korean, Arabic, Russian, and many more. Especially strong for Dutch translations. ### External Services This plugin connects to the Langbly translation API to provide machine translations within the Loco Translate editor. **What it does:** When you click “Auto-translate” in Loco Translate with Langbly selected as the provider, the plugin sends the source text and target language to the Langbly API and receives translated text back. **What data is sent:** The source strings you are translating, the source language code, the target language code, and your API key (for authentication). Data is sent only when you actively request a translation. **Service provider:** Langbly (langbly.com) * [Terms of Service](https://langbly.com/terms) * [Privacy Policy](https://langbly.com/privacy) ## Installation 1.
