Here is an example: ``` https://www.northdata.com/_api/company/v1/company?api_key=XXXX-XXXX®isterId=HRB%20209848®isterCity=Braunschweig&output=xml ``` For countries other than Germany, you should use the country code in addition to the registerId. Here is an example for an API call for a company in Belgium, using registerId:  ``` https://www.northdata.com/_api/company/v1/company?api_key=XXXX-XXXX&output=json&fuzzyMatch=true&extras=true&countries=BE®isterId=KBO%200881.653.685 ``` You can find the companies' register IDs for different countries in the following table: [Register IDs in supported countries](https://github.com/northdata/api/blob/master/doc/data-api-userguide/data-api-userguide.md#appendix-h-register-ids-in-supported-countries) For more technical details, see our [API documentation](https://help.northdata.com/en/center/where-can-i-find-documentation-for-the-api?hsLang=en). -
