What value actually need to provide {item-path} in view.delta OneDrive for Business API -

i using /drive/root:/{item-path}:/view.delta getting changes of file in onedrive business in root folder. have tried path /drive/root:/files/filename:/view.delta response resource not found. can please explain value ?

the link following below.

more details

the error suggest /files/filename not exist, if did you'd run limitation of how view.delta works onedrive business. make long story short, it's limited working on root of drive, i.e. /drive/root/view.delta. using path you'll changes items within drive, not 1 you're interested in.

given you're trying detect changes in single file may want consider standard metadata request if-none-match header contains etag of last state application saw.

---

for example, you'd first make request without additional headers initial state:

request:

get /_api/v2.0/drive/root:/file/filename 

response:

200 ok {   ...   "name": "filename",   "etag": "\"aasdfasdf\"",   "modifieddatetime": "2016-01-01t00:00:00z",   ... } 

---

at point in future you'd make call using etag value in if-none-match header:

request:

get /_api/v2.0/drive/root:/file/filename if-none-match: "aasdfasdf" 

response:

304 not modified 

---

if file has changed you'd new response.

request:

get /_api/v2.0/drive/root:/file/filename if-none-match: "aasdfasdf" 

response:

200 ok {   ...   "name": "filename",   "etag": "\"poihklhjl\"",   "modifieddatetime": "2016-04-19t00:00:00z",   ... }
