How can I choose a language in the Flatfile importer?

To choose a language within the Flatfile importer, use the importer.setLanguage('xx')method. You can use this method right after importer.setCustomer(). The code snippet below shows an example of how to choose a language in the Flatfile importer.

const importer = new FlatfileImporter(
  licenseKey,
  settings
)

importer.setCustomer(customer);
importer.setLanguage("xx");

const importOnClick = () => {
  importer.requestDataFromUser().then(
    // do something
  )
}
