Upload a large excel file using createuploadsession Graph API

Question

Hi @MichaelHan-MSFT ,
I am trying to upload a large excel file using the createuploadsession option in Graph API via Postman. Below are the settings that I selected:

URL: https://graph.microsoft.com/v1.0/sites/<siteID>tenantID>/drive/root/test/testing.xlsx:/createUploadSession

I get the success message but no Upload URL is returned. May I know if I am missing something or any details are incorrect? Also can you tell where I should specify the drive file name(source file) and the Sharepoint filename(destination file)?

Hi @Gopi, Radhika ,

The createuploadsession request doesn't require file in the body, just choose none for the request. We would get the upload URL in the response body. As the below picture shows.

POST https://graph.microsoft.com/v1.0/sites/{siteID}/drive/root:/test/testing.xlsx:/createUploadSession  

Then we could use the Upload URL to upload the large file.

put {upload URL returned}  

In the body, choose the file. ThenAdd two headers Content-Length and Content-Range for the request.

Content-Length : {fileSize in bytes}
Content-Range: bytes 0-{fileSize-1}/{fileSize}

For example:
