The service support all the languages that Power Apps does. The list of codes are below. You can also find them as part of the ValidationSet for the LocaleName parameter in the PowerShell cmdlets. You can put the language code in the Accept-Language header of the rule and analyze API and it will do the translations for you including the results in the SARIF. You may need to tweak your parsing of the SARIF a bit to support it. We do support multiple languages as well passed in the header. We donβt currently have ruleset names being translated.
