import requests

# ONLYOFFICE DocSpace configuration
ONLYOFFICE_API_HOST = "your-docspace.onlyoffice.com"
ONLYOFFICE_API_KEY = "your_onlyoffice_api_key"

# Trello configuration
TRELLO_API_KEY = "your_trello_api_key"
TRELLO_TOKEN = "your_trello_token"
TRELLO_BOARD_ID = "your_board_id"

ONLYOFFICE_HEADERS = {
    "Authorization": f"Bearer {ONLYOFFICE_API_KEY}",
    "Content-Type": "application/json",
    "Accept": "application/json"
}

# Step 1: Get Trello board name
def get_trello_board_name(board_id):
    url = f"https://api.trello.com/1/boards/{board_id}"
    params = {"key": TRELLO_API_KEY, "token": TRELLO_TOKEN}
    response = requests.get(url, params=params)
    if response.status_code == 200:
        return response.json()["name"]
    else:
        print(f"Trello board fetch error: {response.status_code}")
        return None

# Step 2: Create a DocSpace room with board name
def create_docspace_room(room_title):
    url = f"https://{ONLYOFFICE_API_HOST}/api/2.0/files/rooms"
    payload = {
        "title": room_title,
        "roomType": 2,  # Collaboration room
        "private": True
    }
    response = requests.post(url, headers=ONLYOFFICE_HEADERS, json=payload)
    if response.status_code == 200:
        print(f"Room created: {room_title}")
        return response.json()
    else:
        print(f"DocSpace room creation error: {response.status_code}, {response.text}")
        return None

# Run integration
if __name__ == "__main__":
    board_name = get_trello_board_name(TRELLO_BOARD_ID)
    if board_name:
        create_docspace_room(board_name)

Cloud storage integrations

Dropbox connectivity. The new Dropbox integrations support both import and export workflows. Export files from DocSpace using presigned URLs for archiving or backup. Import files directly into specific rooms for centralized document management.

Folder sharing automation. Automatically share Dropbox folders with DocSpace users or group members, creating seamless collaboration bridges between platforms.

Notion and Asana workflows

Notion user integration. Sync Notion workspace users with DocSpace, ensuring consistent access across your documentation ecosystem.

Asana project automation. Generate DocSpace room structures based on Asana projects, with folders automatically created for each task. This creates perfect alignment between project management and document collaboration.

Task-based invitations. Automatically invite Asana task assignees to relevant DocSpace rooms, eliminating manual access management.

DocSpace: Enhanced Plugins SDK

The Plugins SDK receives significant updates with both advanced and basic samples to accelerate plugin development.

Advanced plugin samples

• File extension filter plugin. Adds contextual filtering capabilities with a clean modal interface. Users can filter room contents by file type, improving navigation in document-heavy environments.
• Modal dialog plugin. Demonstrates custom toolbar integration with backend API calls. Create new documents directly from the interface with user-defined parameters.
• Settings plugin UI. Provides administrators with custom configuration interfaces, enabling fine-tuned control over plugin behavior.

Basic component samples

New basic samples cover essential UI components:

• API plugin – shows proper platform API connection handling.
• Box component – layout and spacing configuration examples.
• Button component – interactive element implementation.
• ComboBox component – dropdown selection interfaces.
• Text component – typography and styling options.
• ToggleButton component – binary state controls.

These samples provide the building blocks for more complex plugin development, with clear implementation patterns you can follow.

What’s new for Docs API: Customization

The new suggestFeature parameter gives you granular control over the newly added editor interface element.

const config = {
  editorConfig: {
    customization: {
...
suggestFeature: true,

This parameter controls the visibility of the “Suggest a Feature” menu button in the File tab. Set it to false for internal deployments where feature suggestions aren’t relevant, or keep it true to maintain user engagement with product development.

Docs: New Office API examples

To support diverse use cases, we’ve introduced new document creation samples with practical applications.

• Sequential numbers. Enhance table navigation and row referencing by adding sequential numbering to the first column.
