WOPI protocol and desktop client

Fabio Gollini 1 Reputation point

I have to support co-authoring for Office docs stored in our document storage.

  • our users have an O365 account
  • we plan to develop a WOPI rest API/discovery for "allowing" Office 365 integration

The questions are:

  • what happens if, once I opened the (office) file in the browser, I decide to modify the doc through the desktop application ?
  • Does the desktop client still use WOPI ?
  • If not, what I have to support ?

Now we are using IIS-webdav but we would like to deprecate it.

Thank you

    Hi @Fabio Gollini

    WOPI means Web Application Open Platform Interface protocol, it can be integrated Office for the web with your application.

    For example, if the file host is SharePoint server, you can use OOS open files from SharePoint server, users can edit documents collaboratively with other users using Office.
    If you use Office clients to open these files, it does not supports co-authoring.

    For more, please refer to "Use the WOPI protocol to integrate with Office for the web", "Integrate with Office for the web" and "Co-authoring using Office for the web".
