Editing a post's title

You can update any post's title using the following GraphQL query:

mutation UpdatePostTitle($updatePostTitleId: Int!, $title: String!) {
  updatePostTitle(id: $updatePostTitleId, title: $title) {
    id, title, author, content {
      type, data
    }
  }
}

where $updatePostTitleId is the post's ID and $title is the new title. On success, this will return:

{
  "data": {
    "updatePostTitle": {
      "id": 2,
      "title": "World Hello",
      "author": 1,
      "content": {
        "type": "TEXT",
        "data": "This is the first post on this social media app with a picture. How amazing is this?"
      }
    }
  }
}
