Sharepoint REST - Can we update file metadata while uploading file itself? - sharepoint

Question

Using below Endpoint we can upload file to sharepoint:
https://domain.example.com/_api/web/GetFolderByServerRelativeUrl("FolderRelativeUrl")/Files/add(url="File",overwrite=true)
Using below endpoint we can update the metadata for specific file:
https://domain.example.com/_api/web/GetFileByServerRelativeUrl(URL)/ListItemAllFields
Is it possible to update metadata when we are uploading file itself?
And same while retrieve, we need to fetch metadata along with file.
Basically I am trying to avoid 2 separate calls? Does SharePoint API support this feature?

Answer 1

SharePoint can't provide a REST API to achieve it.
As a workaround, we can use CSOM(C#) to achieve it.
public Boolean UploadDocument(String fileName, String filePath, List metaDataList)
{
SP.ClientContext ctx = new SP.ClientContext("http://yoursharepointURL");
Web web = ctx.Web;
FileCreationInformation newFile = new FileCreationInformation();
newFile.Content = System.IO.File.ReadAllBytes(#"C: \TestFile.doc");
newFile.Url = "/" + fileName;
List docs = web.Lists.GetByTitle(“Shared Documents”);
Microsoft.SharePoint.Client.File uploadFile = docs.RootFolder.Files.Add(newFile);
context.Load(uploadFile);
context.ExecuteQuery();
SPClient.ListItem item = uploadFile.ListItemAllFields;
//Set the metadata
string docTitle = string.Empty;
item["Title"] = docTitle;
item.Update();
context.ExecuteQuery();
}
If you want to call web service using Ajax from UI, we can create a custom web service with CSOM(C#), then consume the web service using Ajax.

It's frustrating, but you can upload the initial version and set metadata in a single call. But not upload new version and set metadata, only as separate calls. I am transfering files from a DMS which can have multiple versions, and the version history in Sharepoint will not match. To make it consistent, I also transfer the initial version and metadata as two calls. The customer is informed, and the version history is ok. The file import shows as an empty version.
