How to create SharePoint list item with Microsoft Graph API? - sharepoint

Question

I am trying to create list items with Microsoft Graph API to a SharePoint endpoint. My URL is as follows:
https://graph.microsoft.com/v1.0/sites/{id}.sharepoint.com:/sites/{name of the site}:/lists/{list_id}/items
Calling this URL with POST, and a body like this:
{
"fields": {
"FileLeafRef": "757391.pdf",
"ContentType": "Document",
"Application_x0020_Name": "ABC",
}
}
It is giving error as
"message": "Files and folders should only be added to a
DocumentLibrary via the OneDrive API"
Can some one help on this, how to fix this issue?
Here I am trying to create metadata for document, with in a list.

Answer 1

You cannot upload a file (i.e. create a new ListItem in a Document Library) like that. You will need to first upload the file using the OneDrive endpoints:
PUT /v1.0/sites/{site-id}/drive/items/{parent-id}:/{filename}:/content
POST /v1.0/sites/{siteId}/drive/items/{driveItem-id}/createUploadSession
Once you have the file in the document library, you can then update the metadata on the existing file using the SharePoint endpoints:
PATCH h/v1.0/sites/{site-id}/lists/{list-id}/items/{listItem-id}/fields
{
"FileLeafRef": "757391.pdf",
"ContentType": "Document",
"Application_x0020_Name": "ABC"
}
