In order to start using Alpaca Web API, you will need to obtain your API key. An API key consists of two strings, one called Key ID which always appears in your dashboard, and Secret Key, which appears only once when generating it. Make sure you keep both in your hands.
Read through our Web API document. It describes how our API works in details so you can prepare for your algorithm to interact with it.
Alpaca also provides software development kits (“SDKs”) here for Python, C#, Go, and Node to help interact with the Alpaca Web API.
