API plugin

This guide walks you through creating an ONLYOFFICE Apps plugin that uses platform API connection parameters (origin, proxy, and prefix) to make authorized requests, such as creating rooms via the REST API.

Before you start

Make sure you have an ONLYOFFICE Apps server running, and install ONLYOFFICE Apps Plugins SDK globally:

npm i -g @onlyoffice/docspace-plugin-sdk

Step 1: Create a plugin

1. Initialize your plugin using the CLI:

   npx create-docspace-plugin

2. Fill out basic metadata: plugin name, version, author, description, logo, license, homepage.

3. Select the required scopes from the list of available options. Use the arrow keys to highlight API, press Space to select it, then press Enter to confirm and generate the plugin template.

Step 2: Confirm plugin configuration

Ensure package.json includes all the necessary fields. Most importantly, make sure it contains:

{
  "scopes": ["API"]
}

Step 3: Review and extend plugin code

By default, the plugin template includes a basic implementation in the src/index.ts file. Here's an example of an API plugin:

import { IPlugin, PluginStatus, IApiPlugin } from '@onlyoffice/docspace-plugin-sdk';

class Apiplugin implements IPlugin, IApiPlugin {
  status: PluginStatus = PluginStatus.active;
  origin = '';
  proxy = '';
  prefix = '';
  apiURL = '';

  createAPIUrl = () => {
    const api = this.getAPI();
    this.apiURL = api.origin.replace(/\/+$/, '');
    const parts = [api.proxy, api.prefix];

    parts.forEach((part) => {
      if (!part) return;
      const trimmed = part.trim().replace(/^\/+/, '');
      this.apiURL += this.apiURL.endsWith('/') ? trimmed : `/${trimmed}`;
    });
  };

  createRoom = async () => {
    const url = `${this.apiURL}/files/rooms`;

    try {
      const response = await fetch(url, {
        method: 'POST',
        headers: {
          'Content-Type': 'application/json',
          Authorization: `Bearer ${window.DocSpacePluginToken}`
        },
        body: JSON.stringify({
          title: 'Plugin-created Room',
          roomType: 2
        })
      });

      if (!response.ok) {
        throw new Error(`HTTP error: ${response.status}`);
      }

      const result = await response.json();
      console.log('Room created:', result);
    } catch (error) {
      console.error('Failed to create room:', error);
    }
  };

  onLoadCallback = async () => {
    this.createAPIUrl();
    await this.createRoom();
  };

  updateStatus = (status: PluginStatus) => {
    this.status = status;
  };

  getStatus = () => this.status;

  setOnLoadCallback = (callback: () => Promise<void>) => {
    this.onLoadCallback = callback;
  };

  setOrigin = (origin: string) => { this.origin = origin };
  getOrigin = () => this.origin;

  setProxy = (proxy: string) => { this.proxy = proxy };
  getProxy = () => this.proxy;

  setPrefix = (prefix: string) => { this.prefix = prefix };
  getPrefix = () => this.prefix;

  setAPI = (origin: string, proxy: string, prefix: string) => {
    this.origin = origin;
    this.proxy = proxy;
    this.prefix = prefix;
  };

  getAPI = () => ({
    origin: this.origin,
    proxy: this.proxy,
    prefix: this.prefix
  });
}

const plugin = new Apiplugin();

declare global {
  interface Window {
    Plugins: Record<string, IPlugin>;
    DocSpacePluginToken: string;
  }
}

window.Plugins = window.Plugins || {};
window.Plugins.Apiplugin = plugin;

export default plugin;

Step 4: Build the plugin

From the root of your plugin, run the following command:

npm run build

This compiles src/index.ts to dist/plugin.js.

Step 5: Upload to ONLYOFFICE Apps

1. Log in as an administrator.
2. Navigate to: Settings → Integration → Plugins.
3. Click Upload plugin, and select the generated dist/plugin.zip.
4. Enable the plugin toggle if it is not already active.

Step 6: Test the plugin

1. Reload the ONLYOFFICE Apps interface.
2. The plugin will automatically trigger onLoadCallback().
3. A new room titled Plugin-created Room should be created automatically.
4. Open the browser console to confirm the plugin sent a request and received a response.

Notes

• You can access:

  • origin: the base URL of the portal;
  • proxy: the proxy segment if used (e.g. /ds);
  • prefix: the API prefix (usually /api/2.0).

• You can expand this plugin to support context menus, main buttons, or settings by updating the scope.
