How do I set a custom user language in the Web SDK instead of relying on the browser's default language?

You can specify a user's language in the Web SDK using one of the following methods. If you use both, the language set with setLanguage wins.

1. During SDK initialization: include the Language tag within the tags object in your init call. If you don't pass it, the SDK uses the browser's language (navigator.language).

   Pushwoosh.push(['init', {
       logLevel: 'info', // error | info | debug
       applicationCode: 'XXXXX-XXXXX',
       apiToken: 'YOUR_DEVICE_API_TOKEN',
       // ... other init parameters
       tags: {
           'Language': 'your_language_code' // e.g., 'en', 'fr', 'es'
       }
   }]);
   

   Replace 'your_language_code' with the language code you want, for example 'en' or 'es' (ISO 639-1).

2. Using the setLanguage function: after the SDK has been initialized, call setLanguage to change the language of the current device. It overrides the value in the Language tag, and the SDK keeps your value on later page loads instead of re-applying the browser language or the init tag.

   Pushwoosh.push(function(api) {
       api.setLanguage('your_language_code'); // e.g., 'en', 'fr', 'es'
   });
   

   Use the language you set to localize push messages and to target users by language in segments.
