Is there any way to connect SharePoint online with Graph API using SharePoint Online Credentials?

Question

I have a requirement like creating .net core console application to communicate with SharePoint Online Resources using Graph API. while surfing i found only Access token is using to communicate with SharePoint. Is there any way to use SharePoint Online credentials with Graph API to communicate with SharePoint online?

Answer 1

You can do this using the SharePoint Online Client Object Model as long as your are willing to use the full .NET Framework. At this point in time the library does not support .NET Core.

Here's some sample code you can use to get started:

var siteUrl = "https://contoso.sharepoint.com";
var loginName = "[email protected]";
var password = "bosco";

var securePassword = new SecureString();
password.ToCharArray().ToList().ForEach(c => securePassword.AppendChar(c)); 

using (var context = new ClientContext(siteUrl))
{
    context.Credentials = new SharePointOnlineCredentials(
        loginName, securePassword);

    var web = context.Web;
    var list = web.Lists.GetByTitle("Site Pages");

    var query = new CamlQuery();
    query.ViewXml = "<View />";
    var items = list.GetItems(query);
    context.Load(items, c => c.Include(li => li.File.Name));
    context.ExecuteQuery();

    foreach (var item in items)
    {
        Console.WriteLine(item.File.Name);
    }
}
