I can create a nested folder /folder1/folder2 in (personal) OneDrive with the following Graph request (using the beta API):
POST drives/{id}/root:/folder1:/children
{
"name": "folder2",
"folder": {},
"@microsoft.graph.conflictBehavior": "fail"
}
Here, folder1 didn't exist beforehand; the one API call creates both it and folder1/folder2.
However, the same code fails for SharePoint and OneDrive for Business with a 404 error. Is this type of request supported? I'd rather not have to make a separate API call for every level of nesting.
I'm asking this because I'm not sure whether my site has policies that cause the request to fail, or because the API actually doesn't support it.
parent-item-idto create a folder. The only way is it make a separate API call for every level as you said. You can get the path property in the response when you create a folder, you can use it to automate calls easily.
