Spotware constantly improves the cTrader Open API which includes adding new SDKs for popular languages. However, there is a small chance that the language you are using may not have its own SDK yet.
In this case, you can always rely on external SDKs created by developers with no affiliation to Spotware. This page lists some of these SDKs. Please note that inclusion in this list does not automatically constitute endorsement.
While external SDKs can be very helpful, note that Spotware does not monitor their dependencies and is not responsible for their maintenance. Spotware is also not responsible for any risks that can be incurred by installing and using third-party SDKs.
Mida is a trading framework that you can rely on to integrate with the cTrader Open API when using Node.js.
