I know, how I can add posts ( Admin API):

```auto
const html = '<h1>Hello World</h1>';

api.posts.add({
    title: 'Migrating to Ghost - HTML card',
    status: "published",
    mobiledoc: JSON.stringify({
        version: '0.3.1',
        markups: [],
        atoms: [],
        cards: [['html', {cardName: 'html', html: html}]],
        sections: [[10, 0]]
    })
})
    .then(response => console.log(response))
    .catch(error => console.error(error));

```

I know that `mobiledoc` is deprecated.

How can I do the same with `lexical`?  
Where can I find docs about `lexical`?

Or can I always use `mobiledoc` because it’s automatically converted to `lexical`?

Thanks  
Joe

I have halfway found a solution. I read a post and analyze the lexical value.

Output:

```auto

  id: '6838afe34e90655353430384',
  uuid: '36962a24-3e7e-46dd-9561-8ba8a8a42ecb',
  title: 'Migrating to Ghost - HTML card',
  slug: 'html-card',
  mobiledoc: null,
  lexical: '{
  "root": {
    "children": [
      {
        "type": "html",
        "version": 1,
        "html": "<h1>Hello World</h1>",
        "visibility": {
