Hi @John Joseph Mathichiparambil - EW
I recommend that you use the graph SDK to create a graphClient
object to call this endpoint. I just tested it locally and it works fine for me.
var users = await graphClient.Users.GetAsync((requestConfiguration) =>
{
requestConfiguration.QueryParameters.Filter = "startswith(displayName,'xxxxx')";
requestConfiguration.QueryParameters.Select = new string []{ "id","givenName" };
});
Hope this helps.
