# API Endpoints

When you create a `ContentType` you will have a certain number of REST API endpoints available to interact with it.

As an example let's consider the `Post` ContentType for the next steps.

### `Post` ContentType

| Fields | Type   | Description        | Options      |
| :----- | :----- | ------------------ | ------------ |
| title  | string | Post's title       |              |
| cover  | media  | Post's cover image |              |
| seo    | group  | Post's seo group   | `repeatable` |

### `Seo` Group

| Fields  | Type   | Description    |
| :------ | :----- | -------------- |
| name    | string | Meta's name    |
| content | text   | Meta's content |

Whether you are using MongoDB or a SQL database you can use the field `id` as described in this documentation. It will be provided in both cases and work the same way.

## GraphQL

When you are using the GraphQL plugin, all your `ContentTypes` will be generated in your Graphql schema and made accessible through queries and mutations.

If you are using `Groups`, they will be available as fields in the `ContentTypes` they are used in.

```graphql
type Post {
  title: String
  cover: UploadFile
  seo: [GroupSeo]
}

type GroupSeo {
  name: String
  content: String
}

type Query {
  post(id: ID!): Post
  posts(sort: String, limit: Int, start: Int, where: JSON): [Post]
}

type Mutation {
  createPost(input: createPostInput): createPostPayload
  updatePost(input: updatePostInput): updatePostPayload
  deletePost(input: deletePostInput): deletePostPayload
}
```

You can read more about the graphql plugin [here](./graphql.md).
