I want to be able to upload a text document to a SharePoint List. Since it is actually a Document Library, I believe I should upload files as though I am uploading to a Drive. I can upload a file to the site's root location. I can get the ID of the List I wish to upload to. However the Microsoft Graph API does not appear to like the ID I provide when I use that as the destination. ListItem says that ListItems are exposed as DriveItems when using a Document Library. How to upload a small file to SharePoint.
I have been testing with C# and GraphExplorer. It boils down to my endpoint being incorrect.
When using Graph Explorer, I can query for all drives with these two queries:
graph.microsoft.com/v1.0/sites/{siteid}/drives
The query displays the Drive Name I am looking for and the ID it shows is different than its list ID. This indicates to me that a Document Library has a separate List ID and Drive ID.
Status Code 201 (Created): graph.microsoft.com/v1.0/sites/{siteid}/drive/items/root:/testplaceholder.txt:/content
Status Code 404 (Not Found): graph.microsoft.com/v1.0/sites/{siteid}/drive/items/{listid}:/testplaceholder.txt:/content
Status Code 400 (Bad Request): graph.microsoft.com/v1.0/sites/{siteid}/drive/items/{driveid}:/testplaceholder.txt:/content
Can anyone tell me where my understanding is lacking, or where I might have messed up? Sorry for the lack of code formatting, couldn't get it to work on the URL strings.
ANSWER:
Using the Drive ID I found with the first query above.
graph.microsoft.com/v1.0/sites/{siteid}/drives/{driveid}/root:/testplaceholder.txt:/content
