Introduction:<\/strong><\/p>\n

In our earlier blog<\/a>, we discussed about creating folders and uploading files on the SharePoint Online through workflows\/plugins using REST.<\/p>\n

In this blog, we will see how we can set the metadata of the uploaded files using REST.<\/p>\n

Below is the code snippet to set the<\/strong> metadata of a file using REST:<\/strong><\/p>\n

\/\/Here first create the JSON string of file metadata\r\nstring result = @\"{'__metadata': { 'type': 'SP.ListItem'}, 'Aliases':'My File.docx', 'Owner':'CRM Owner', 'Date':'1\/7\/2017'}\";\r\nstring siteUrl = \u201chttps:\/\/crmtrial.sharepoint.com\u201d \r\nUri spSite = new Uri(siteUrl);\r\nprivate SpoAuthUtility _spo = SpoAuthUtility.Create(spSite, _username, WebUtility.HtmlEncode(_password), false);\r\n\/\/read the digest\r\nstring digest = _spo.GetRequestDigest();\r\n\/\/convert JSON data to bytes\r\nbyte[] content = ASCIIEncoding.ASCII.GetBytes(result);\r\n\r\n\/\/define the file URL to set the metadata\r\nstring fileURL = Account\/Test Account Folder\/TestFile.docx;\r\nvar requestUrl = string.Format(\"{0}\/_api\/web\/GetFileByServerRelativeUrl('{1}')\/ListItemAllFields\", siteURL, fileURL);\r\n\r\nvar webRequest = (HttpWebRequest)HttpWebRequest.Create(requestUrl);\r\n                webRequest.Headers.Add(\"X-RequestDigest\", digest);\r\n                webRequest.Headers.Add(\"X-HTTP-Method\", \"PATCH\");\r\n                webRequest.Headers.Add(\"If-Match\", \"*\");\r\n                webRequest.Accept = \"application\/json;odata=verbose\";\r\n                webRequest.ContentType = \"application\/json;odata=verbose\";\r\n                webRequest.Method = \"POST\";\r\n\r\n                \/\/ Send a json odata request to SPO rest services to fetch all list items for the list.\r\n                byte[] result = HttpHelper.SendODataJsonRequest(\r\n                  new Uri(requestUrl),\r\n                  \"POST\", \/\/ reading data from SP through the rest api usually uses the GET verb \r\n                  content,\r\n                  webRequest,\r\n                  _spo \/\/ pass in the helper object that allows us to make authenticated calls to SPO rest services\r\n                  );\r\n\r\n                \/\/read the response\r\n                string response = Encoding.UTF8.GetString(result, 0, result.Length);<\/pre>\n
If you go to the uploaded file\u2019s properties in SharePoint, you can see the metadata of the file as shown in the screenshot below;<\/p>\n
