To add office functionality to a web app with ONLYOFFICE, embed its browser-based editors using the Docs API or build a host integration around WOPI. In either case, your application still owns document storage, file permissions, and document management; the editor is not a replacement for those parts of your app.
What ONLYOFFICE provides—and what your app must provide
ONLYOFFICE Docs supplies browser-based editors for documents, spreadsheets, presentations, PDFs, and fillable forms. Its Docs API lets a web app load and configure those editors. You can load editors from the ONLYOFFICE Docs Cloud CDN or install the self-hosted solution; choose based on operational needs such as control, network access, and maintenance. The vendor documentation cited here does not establish current pricing or comparative service guarantees. See ONLYOFFICE’s basic concepts.
The application remains responsible for the surrounding document workflow. Typically, your document manager selects a file and supplies its identity and URL in the editor configuration. The Docs service retrieves the document from that URL and handles editing-related services, while your storage remains under your control. Your app must continue to manage files, permissions, and metadata; embedding an editor does not provide those functions. The ONLYOFFICE architecture overview describes the division of work.
Choose an integration route
| Route | What your app must do | Best fit |
|---|---|---|
| Docs API | Configure the editor in your web app and provide the document identity and URL. | A host that wants the direct documented editor-integration route. |
| WOPI | Implement the WOPI host protocol, discovery, iframe session, access-token parameters, proof-key verification, and supported file operations; enable WOPI in Docs configuration. | A host whose architecture and protocol expertise suit a WOPI-based integration. |
ONLYOFFICE documents WOPI support beginning with Docs version 6.4; this is the vendor-stated compatibility threshold, not a statement of the current release. Review the WOPI overview and WOPI FAQ before choosing that route. The FAQ lists these host-side operations: CheckFileInfo, GetFile, Lock, RefreshLock, Unlock, PutFile, and RenameFile.

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
For the Docs API, ONLYOFFICE provides language-specific examples for .NET, Java, Java Spring, Node.js, PHP, Laravel, Python, Ruby, and Go. Use the integration samples as a starting point, not as a finished production integration.
Plan the document flow and network access
Before implementing the editor, identify where documents, permissions, and metadata live. Then make sure the Docs service can retrieve documents from the URLs your app supplies and that your application can reach the configured Docs service endpoints for the required interactions. ONLYOFFICE’s integration FAQ advises checking reachability from both sides. Network rules, URL accessibility, and save handling need to match your deployment rather than assuming that a browser-visible app URL is also reachable by the Docs service.

- Map the responsibilities. Record which service owns each file, who can open or edit it, and how document identity and metadata are represented.
- Select the integration route. Use the Docs API for the direct editor configuration path, or WOPI if you are prepared to implement its host protocol.
- Configure reachable endpoints. Verify that the Docs service can fetch the configured document URLs and that your application can communicate with the Docs service.
- Adapt an official example. Start with a language sample that matches your stack, then add your own authorization and validation before exposing it to users.
- Test saving and access control. Exercise authorized and unauthorized file access, normal saves, and invalid or altered requests in your application’s deployment environment.
Secure the integration before launch
ONLYOFFICE documents JWT tokens signed with a shared secret between the integrator and Docs. In the documented flow, Docs validates the token and rejects a missing or invalid token. Configure token validation and keep the shared secret protected; see the ONLYOFFICE security documentation.
The official examples demonstrate integration mechanics, but the vendor warns that they lack production authorization, parameter-substitution checks, and complete save-request validation. The samples page states: “DO NOT USE these examples on your own server without PROPER CODE MODIFICATIONS!” Add authorization checks for each document operation, validate parameters, and verify save requests against your application’s rules before production use.

WOPI has additional host-side security work. Enabling the protocol does not itself secure the data flow: configure access restrictions, filter trusted integrators as appropriate, and validate signed requests and proof keys according to the WOPI documentation and WOPI FAQ.
