Query parameters are a defined set of parameters attached to the end of a URL. They are extensions of the URL that are used to help define specific content or actions based on the data being passed. To append query parameters to the end of a URL, a question mark ('? ') is added, followed by the parameter.
A number of query parameters are supported for HP redirect. These include parameters that improve the UX by eliminating unnecessary or extraneous user selection, as well as authentication and session parameters using direct references to existing and/or stored TPP requests.
Supported query parameters for localization currently comprise language (lang) and country (country).
You can specify a particular language by passing its alpha-2 language code (lang=country-code) as a query parameter appended to the redirect URI. Here's an example for passing the desired ISO 639-1 language code for German (de).

Similarly, to specify a desired country, append an ISO alpha-2 country code to the URI using the country parameter (country=country-code). Austria, for example, would be:
