There are multiple possibilities of getting a story, here are two:

The first one is the same as in the Quickstart. Use the resolver called story where you can pass a slug (being the visible integer in the url of a story).

Example: Get the title and the name of its author of the latest version of the story with the slug 123

graphql
query {
    story(slug: 123) {
        id
        slug
        version {
            title
        }
        user {
            name
        }
    }
}

This should return a JSON like this:

response
{
    "data": {
        "story": {
            "id": "TWU6MTIz",
            "slug": 123,
            "version": {
                "title": "Hello world!"
            },
            "user": {
                "name": "John Doe"
            }
        }
    }
}

The second one is a query via the entry point called node by using the GraphQL id, for more information about it see the Introduction to GraphQL section.

For example:

graphql
query {
    node(id: "az3QSdkm") {
        ... on Story {
            id
            version {
                title
            }
            user {
                name
            }
        }
    }
}

Note the difference with the previous one, wrapping the fields in ... on Story that is allowing us to cast the expected return to be a Story.

The only difference with the previous example in the returned data will be the name of the variable:

Instead of:

response
{
    "data": {
        "story": {
            "id": "TWU6MTIz"
        }
    }
}

You will receive a structure like this:

response
{
    "data": {
        "node": {
            "id": "TWU6MTIz"
        }
    }
}

If you want to have the same response, you can add an alias to node. For example, in this case in the query you could do:

graphql
query {
    story: node(id: "az3QSdkm") {
        ... on Story {
            id
        }
    }
}
