I have some troubles with the sharepoint api and i hope to get some help here ;-)
We want to build an app to update sites and lists on a sharepoint website, but unfortunately a needed function is not working in graph. We want to insert/update items in a list. We noticed, that this issue isn't new: Graph API does not support to create link columns in a list or on github link-column in sharepoint lists. So we have to switch to the old sharepoint api instead of the graph api. But thats not the question right now;-).
I've already seen the link on stackoverflow insert-item-in-list-via-rest where's a description how to insert list items in sharepoint in c#.
The first step is to obain the X-RequestDigest-Cookie via an empty POST request. And this post-request is what my question is about:
I am wondering how to do this post request to get the X-RequestDigest-Cookie via Postman
I tried: POST
Into the URL field i put: myname.sharepoint.com/_api/contextinfo
The Headers i've set are:
Accept: application/json; odata=verbose
Content-type: application/json; odata=verbose
At least the client credentials should be added. But how to? I added my sharepoint username and password into the authorization field of postman, there i tried a few variants like basic, ntlm or api-key. But i always get an 401 unauthorized error. I don't know what i do wrong. Where have to be the client credentials in postman? Or do i have to use client_id and client_secret? :O Can anybody help me?
(The settings in the Azure-Portal should be sufficient. We gave the Sharepoint-API the same permissions like the graph-api)
Thanks for a reply!
