Access a particular post via ID

Note: I don’t speak English, so I’m using Google Translate

I’m a beginner in programming and I’m creating a blog in Reactjs and I would like to use Dato CMS for that! I managed to connect with the API, but I don’t know how I can access a post completely through the unique ID. Can someone help me?
