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:

1. During SDK Initialization: Include the Language tag within the tags object in your init call. This value will be associated with the user's profile.

   Pushwoosh.push(['init', {
       logLevel: 'debug', // Or your preferred log level
       applicationCode: 'YOUR_APPLICATION_CODE',
       safariWebsitePushID: 'web.your.domain.identifier', // For Safari
       defaultNotificationTitle: 'Your Default Title',
       defaultNotificationImage: 'https://example.com/default-image.png',
       autoSubscribe: true,
       userId: your_user_id_variable, // Optional: Your internal user ID
       // ... other init parameters
       tags: {
           'Language': 'your_language_code' // e.g., 'en', 'fr', 'es'
       }
   }]);
   

   Replace 'your_language_code' with the desired ISO 639-1 language code (e.g., 'en' for English, 'es' for Spanish) obtained from your application's settings.

2. Using the setLanguage function: After the SDK has been initialized, you can use the setLanguage API call to update the language. This function specifically sets the language for the device, which can be used for localization of system messages or campaigns targeted by language.

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

   This will update the language for the current user/device. Using the Language tag is generally recommended for segmentation purposes, while setLanguage directly influences SDK behavior related to language.
