# API · Docs · Create a long-form document

POST https://api.simplified.com/api/v1/documents
Content-Type: application/json

Create a new long-form document rendered in the Quill editor.
Content is stored as Quill Delta JSON (ops array). Used by
AI-writer skills (Essay Writer, Article Writer) to persist
generated markdown content into an editable document.

The returned document is immediately openable at
`/ai-writer/document/{space_or_organization}/{id}` in the Simplified web app.

To convert markdown content into the required Quill Delta
shape, call `markdown_to_quill_delta` from the writers toolkit
before passing to this endpoint.

Reference: https://docs.simplified.com/api-reference/platform/documents/create-document

## Authentication

- `Authorization` header (required) (prefixed with ` Api-Key   `) — Header authentication of the form `Api-Key  <token>`
- `Authorization` header (bearer token, required) — Bearer authentication of the form `Bearer <token>`, where token is your auth token.

## Request

### Body (application/json)

This endpoint expects a CreateDocumentRequest.

- `title` (string, required) — Document title shown in the editor and the document list. For AI-writer skills, use the essay/article title from the originating show_article tool call.
- `form` (integer, required) — Document form type enum. Use 1 for LONG_FORM (Quill-editor-backed documents — the standard for essays, articles, and any rich-text content). 0 = SHORT_FORM (AI templates, not used by these skills).
- `content` (CreateDocumentRequestContent, required) — Quill Delta JSON representing the document body. Contains an `ops` array of operations. Each op is a dict with `insert` (string or embed object) and optional `attributes` (formatting like bold, italic, header, list, link, code-block, blockquote). For markdown-sourced content, call `markdown_to_quill_delta` to produce a compliant Delta before passing to this field.
- `payload` (CreateDocumentRequestPayload, optional) — Optional document metadata. Can be left empty (). Supported fields: description, tone, keywords, voice\_id, output. Used for AI template context — not required for skill-generated content.
- `parent` (string, optional) — Optional parent document id for creating a sub-document. Not used by AI-writer skills in v1.

## Response

### 201

Document created — returns document id plus workspace context

- `any`

## Errors

### 400 Bad Request Error

Invalid payload (missing title, content, or malformed Delta)

- `any`

### 401 Unauthorized Error

Unauthorized

- `any`

## Types

### CreateDocumentRequestContent

Quill Delta JSON representing the document body. Contains an `ops` array of operations. Each op is a dict with `insert` (string or embed object) and optional `attributes` (formatting like bold, italic, header, list, link, code-block, blockquote). For markdown-sourced content, call `markdown_to_quill_delta` to produce a compliant Delta before passing to this field.

- `ops` (list of CreateDocumentRequestContentOpsItems, required) — Delta operations array

### CreateDocumentRequestPayload

Optional document metadata. Can be left empty (). Supported fields: description, tone, keywords, voice\_id, output. Used for AI template context — not required for skill-generated content.
