I am trying to get a Python script to upload files in an organization SharePoint. I am not the admin of said SharePoint, so I believe I can't add application permissions in Microsoft Graph. However, I also don't want to access the sharepoint with my e-mail and password in the Python script. The SharePoint folder I am trying to acces has a shared-link with a share-password. Those can be used by anyone to access the Sharepoint folder and edit files in it.

Now my question, what do I have to do, so that Python uses the shared link and password to upload files as guest?

I already tried logging in the SharePoint with my Organization-account, which worked perfectly. However, I never got a Python script working, where it was using client_id, etc. to authenticate. That's mainly why I don't want to use Microsoft Graph. If there is an easy fix, let me know.

I tried the usual

app_principal = {  
'client_id': client_id,  
'client_secret': secret_id,  
}  

context_auth = AuthenticationContext(url=site_url)  
context_auth.acquire_token_for_app(client_id=app_principal['client_id'], client_secret=app_principal['client_secret'])  

ctx = ClientContext(site_url, context_auth)  
web = ctx.web  
ctx.load(web)  
ctx.execute_query()  
print("Web site title: {0}".format(web.properties['Title']))

But I can't get authenticated, I also tried to get an access token, which I do, but I don't know how to use the access token to get authenticated. I believe I have said problems, because I don't have admin permissions. HOWEVER, in SharePoint I can create a shared-link with a shared-link-password. So why can't I just take both of those and upload files as guest from Python?

  • what have you tried so far ? the question needs sufficient code for a minimal reproducible example Commented Apr 14, 2024 at 11:21
  • aside from the above. you will need permissions (from the Admin) or nothing will work... Commented Apr 14, 2024 at 11:22
  • I think adding code doesn't improve anything. I tried the usual app_principal = { 'client_id': client_id, 'client_secret': secret_id, } ...

  • This is either an password Admin question, in which case you need to speak to the admin, or a Coding question. It seems to be the former... Commented Apr 15, 2024 at 7:31
  • There is no need to update, since it still is not working. I do not understand, why I have such big problems connecting to SharePoint. Every delegated method works fine with OneDrive, but I do not get anything to authenticate to SharePoint except putting my username and password in a Python script... Commented Apr 24, 2024 at 12:23
