The Alpaca API has four SDKs available for Python, TypeScript/JS, C#/.NET, and Go, with the most recent updates shipped through these SDKs. The last update was made to the CSharp SDK in the past month. To use the latest functionality, developers can install the corresponding SDK using pip3, npm, dotnet add package Alpaca.Markets, or go get -u github.com/alpacahq/alpaca-trade-api-go/v2/alpaca. The recent update includes fixes to several methods, including ListExchangesAsync, ListTradeConditionsAsync, and ListQuoteConditionsAsync, which now work correctly when provided with the correct authentication data.
