Adding note to Office 365 contact

Question

Hi there!
I'm using the Office 365 REST API to interact with contacts. I know that Exchange is behind Office 365, so maybe you can help me with this question...
First, I get the contact ID by querying:
https://outlook.office365.com/ews/odata/Me/Contacts
Then I need to add a note to a contact with a specific ID. I'm using the following code:
public void UpdateContact(string id, string note)
JObject updateRequest = new JObject();
updateRequest["Body"] = note;
byte[] byteArray = Encoding.UTF8.GetBytes(JsonConvert.SerializeObject(updateRequest));
HttpWebRequest webRequest = WebRequest.Create(String.Format("https://outlook.office365.com/ews/odata/Me/Contacts('{0}')", id)) as HttpWebRequest;
webRequest.Method = "PATCH";
// Add the Authorization header with the basic login credentials.
string authHeader = "Basic " + Convert.ToBase64String(Encoding.UTF8.GetBytes(user + ":" + password));
webRequest.Headers.Add("Authorization", authHeader);
webRequest.Accept = "application/json";
webRequest.ContentType = "application/json";
webRequest.ContentLength = byteArray.LongLength;
using (Stream dataStream = webRequest.GetRequestStream())
dataStream.Write(byteArray, 0, byteArray.Length);
// Send the request.
webRequest.GetResponse();
But I'm getting a 400 Bad Request response.
I found that notes are the body of the Contact, but how can I set that value? What am I doing wrong here?
Any hint will be greatly appreciated!
Thanks!

Hi Ernesto,
Not very much sure if you are targetting the correct attribute.
However the NOTES attribute is called "info" in AD.
Below is an example:
SET-ADUSER john.smith –replace @{info=”John Smith is a Temporary Contractor”}
As for Exchange Online, you might be missing 'S' in notes :
Notes
System.String
The Notes parameter specifies additional information about the user.
Set-User -Identity Contoso\Jill -DisplayName "Jill Frank" -Notes "Jill Frank is a Permanent Employee"
