[SOLVED] HERE API Autocomplete Country Code ISO Alpha 2

HERE API Autocomplete Country Code ISO Alpha 2

Is there a way to receive the ISO Alpha-2 country code from the HERE autocomplete API instead of the 3-letter ISO country codes? The documentation (https://developer.here.com/documentation/geocoder-autocomplete/dev_guide/topics/resource-suggest.html) doesn't say anything about this but other APIs from HERE do return the Alpha-2 code. If the API itself doesn't do it, is there another API we can use to convert the country code? Any help appreciated.

Solution

The HERE Autocomplete API currently only returns ISO 3166-1 alpha-3 country codes (e.g. NLD, DEU, USA).
Unlike other HERE endpoints (like Geocoding & Search), it does not provide the 2-letter (alpha-2) variant in its payload, and there’s no query parameter or flag to change that.

Convert alpha-3 → alpha-2 yourself using a lib like i18n-iso-countries
The mapping is fixed and public under the ISO 3166-1 standard.
You can safely convert locally instead of calling another API.

import countries from "i18n-iso-countries";

const alpha2 = countries.alpha3ToAlpha2("USA"); // → "US"
