Did 404 change to 409 in v2?

[philipkd]

I'm migrating Nebulous Notes to v2, and I noticed that if I sync a file that doesn't exist on DB, I get a 409, instead of 404. Is this intentional? I use the status check in my logic to determine whether or not to upload a file, and want to make sure I set it to the right code.

Yes, API v2 makes different use of status codes than API v1. For example, where API v1 may have used a 404 to indicate a non-existent file (among other issues), that would be a 409 error in API v2, with more specific error information available in the body.

You can find information on the design of API v2 on the blog:

You can find more information on error handling in the API v2 documentation:

Hope this helps!
