I see official documentation says this:
but I do some testing, this what I got:
{
"key": "OnlyOffice.wordtest.WebHome",
"status": 6,
"url": "http://172.25.161.211/cache/files/OnlyOffice.wordtest.WebHome_5341/output.docx/output.docx?md5=3vL8xAsnC5cKVxQYMup0rQ&expires=1639205564&filename=output.docx",
"changesurl": "http://172.25.161.211/cache/files/OnlyOffice.wordtest.WebHome_5341/changes.zip/changes.zip?md5=5uvaX7i81LXLI1atzRNzew&expires=1639205564&filename=changes.zip",
"history": { "serverVersion": "6.4.2", "changes": [{ "created": "2021-12-11 06:10:21", "user": { "id": "uid-1639041324340", "name": "WestFarmer (Guest)" } }] },
"users": ["uid-1639041324340"],
"actions": [{ "type": 2, "userid": "uid-1639041324340" }],
"lastsave": "2021-12-11T06:37:42.000Z",
"forcesavetype": 1
}
as you can see, url is present when status==6
