Have a 3rd party connector trying to use the Web API 1.2 to insert media items in to Sitecore. We are on Sitecore 9 and all the URLs are throwing a 404. The URLs start with "/-/item/v1/".
It looks like it was actively developed until 7.1 but was replaced by Item Web API v2. There seems to be a page for downloading the module but it doesn't work: https://doc.sitecore.com/en/SdnArchive/Products/Sitecore%20Item%20Web%20API/SitecoreItemWebApi12.html.
Has it been deprecated and deleted?
