The endpoint returns the client categorization questionnaire that the user needs to respond during the onboarding process before starting investing.You can pass the parameter Accept-Language with a string containing ISO 639-1 language code to get the questionnaire translated into the chosen language. Currently, Bitpanda supports translations for German, Polish, French, Spanish, Italian, and Turkish. The default language is English (en). If you pass the parameter for a language that does not have an existing translation in our database, the response returns the questionnaire in English.
