Open the OneNote client

You can use the links property of a page or notebook to open a OneNote application to a particular page or notebook.

The links property is a JSON object that contains two URLs. The URLs will open the page or notebook in the OneNote client application or in OneNote on the web.

    "links": {
        "oneNoteClientUrl": {
            "href": "onenote:https://..."
        "oneNoteWebUrl": {
            "href": "https://..."
  • oneNoteClientUrl

    • Opens the OneNote client if it is already installed on the device. This URL includes the onenote prefix.
    • Opens the language-specific version if one is installed on the device. Otherwise, uses the platform language setting.
  • oneNoteWebUrl

    • Opens OneNote on the web if the default browser on the device supports it.
    • Uses the browser language setting.

The OneNote API returns the links property in the HTTP response for the following operations:

The following examples show how to check the status code of the response, parse the JSON to extract the URLs, and then open the OneNote client.

iOS example

The following example gets the OneNote client URLs from the JSON response. It uses the AFNetworking library ( to extract the two URLs. In the example, created is a pointer to the ONSCPSStandardResponse object used to store the response values, and responseObject holds the parsed JSON.

    /* Import the JSON library */
    #import "AFURLRequestSerialization.h"

    - (void)connectionDidFinishLoading:(NSURLConnection *)connection {
            if(delegate) {
                  int status = [returnResponse statusCode];
                  ONSCPSStandardResponse *standardResponse = nil;
                  if (status == 201) {
                        ONSCPSCreateSuccessResponse *created = 
                              [[ONSCPSCreateSuccessResponse alloc] init];
                        created.httpStatusCode = status;
                        NSError *jsonError;
                        NSDictionary *responseObject = 
                              [NSJSONSerialization JSONObjectWithData:returnData options:0 error:&jsonError];
                        if(responseObject && !jsonError) {
                              created.oneNoteClientUrl = ((NSDictionary *)
                                    ((NSDictionary *)responseObject[@"links"])[@"oneNoteClientUrl"])[@"href"];
                              created.oneNoteWebUrl = ((NSDictionary *)
                                    ((NSDictionary *)responseObject[@"links"])[@"oneNoteWebUrl"])[@"href"];
                  standardResponse = created;
                  else {
                        ONSCPSStandardErrorResponse *error = [[ONSCPSStandardErrorResponse alloc] init];
                        error.httpStatusCode = status;
                        error.message = [[NSString alloc] initWithData:returnData 
                        standardResponse = error;
                  // Send the response back to the client.
                  if (standardResponse) {
                        [delegate exampleServiceActionDidCompleteWithResponse: standardResponse];

After you parse the URLs from the response, you can open OneNote by using the following code. Use oneNoteClientUrl to open the installed OneNote client or oneNoteWebURL to open OneNote on the web.

NSURL *url = [NSURL URLWithString:standardResponse.oneNoteWebUrl];
[[UIApplication sharedApplication] openURL:url];

Android example

First, check for the success status code, and then parse the JSON. The example assumes a POST request was sent, so it checks for a 201 Created status code. If you made a GET request, check for a 200 status code instead.

public ApiResponse getResponse() throws Exception {
    /* Get the HTTP response code and message from the connection object */
    int responseCode = mUrlConnection.getResponseCode();
    String responseMessage = mUrlConnection.getResponseMessage();
    String responseBody = null;

    /* Get the response if the new page was created successfully. */
    if ( responseCode == 201) {
        InputStream is = mUrlConnection.getInputStream();

        /* Verify that this byte array is big enough. */
        byte[] b1 = new byte[1024];
        StringBuffer buffer = new StringBuffer();

        /* Copy the body of the response into the new string. */
        /* Make sure the buffer is big enough. */
        while ( != -1)
            buffer.append(new String(b1));

      /* When the returned data is complete, close the connection 
         and convert the byte array into a string. */
        responseBody =  buffer.toString();

    /* Create a new JSON object, and an object to hold the response URLs. */
    JSONObject responseObject = null;
    ApiResponse response = new ApiResponse();
    try {

        /* Store and verify the HTTP response code. */
        if ( responseCode == 201) {

            /* Retrieve the two URLs from the links property. */
            responseObject = new JSONObject(responseBody);
            String clientUrl = responseObject.getJSONObject(
            String webUrl = responseObject.getJSONObject(
    } catch (JSONException ex) {

        /* If the JSON was malformed or incomplete... */
        String msg = ex.getMessage();
        msg = msg;
    return response;

Using the response properties, your app can open OneNote on the web, as shown in the following example.

if (response.getResponseCode() == 201) {
    Uri uriUrl = Uri.parse(response.getOneNoteWebUrl);  
    Intent launchBrowser = new Intent(Intent.ACTION_VIEW, uriUrl); 

Or your app can open the OneNote client on an Android device. When using the oneNoteClientUrl property, you must surround the GUID strings with braces { } before starting the Intent. The following example shows how to do that.

if (response.getResponseCode() == 201) {

    // Get the URL from the OneNote API JSON response.
    String onenoteClientUrl = obtainClientLinkFromJSONResponse();
    String androidClientUrl = 

    // Open the URL: Open the newly created OneNote page.
    Uri uriUrl = Uri.parse(androidClientUrl);  
    Intent launchBrowser = new Intent(Intent.ACTION_VIEW, uriUrl);
