I am using OneDrive rest API for my webapp using the code flow. I see some HTTP request samples in this page for uploading large files. It says that to begin a large file upload, I must first request a new upload session. But all of listed samples are containing {itemId}
in its header. The question is how can I have the {itemId}
before creating upload session?
/drive/root:/{item-path}:/createUploadSession
"item-path" is the name of the folder that you will be uploading to. You can use folder name (eg: uploads)
