OneDrive file picker SDK for JavaScript

The OneDrive picker and saver SDK for Web apps is the fastest way to integrate OneDrive into your website. Open and save files to OneDrive by using a button, or just a few lines of JavaScript - all without handling authentication. The OneDrive picker and saver SDK for Web apps is different from other OneDrive picker and saver SDKs because you can start using it without downloading anything.

When using the picker to open files from OneDrive, you get shareable links to files, which are great for web viewing and sending to friends and family, or downloadable links, which are great for getting the contents of a file. You also get thumbnails of image and video files for simple, fast displays.

In this guide, we’ll show you how to get your app quickly opening and saving files on OneDrive.

Setting up

Register your app to get an app ID (client ID), if you haven't already done so. Ensure that the web page that is going to reference the SDK is a Redirect URL under API Settings. You can also upload your application logo, which OneDrive will display in the picker and saver experience.

Then, to start opening or saving files, include this reference in your web page, replacing APP_ID with your app's ID or client ID.

<script type="text/javascript" src="" id="onedrive-js" client-id="APP_ID"></script>

Opening files from OneDrive

To open files from OneDrive, your app can either embed an "Open from OneDrive" button, or provide a customized button and programmatically start the OneDrive picker experience. Both methods require a pickerOptions object with the following parameters.

Parameter name Description
success Required. Called when the user finishes picking files and passes an array of file objects to the provided function.
cancel Called if the user cancels the picker.
linkType The type of link to create for access to the file. The default value is webViewLink, which returns a URL to a sharing link that provides a web preview of the file. This link is valid until the user deletes the shared link through OneDrive. The downloadLink gets a URL that provides access for one hour directly to the contents of the file. You can use this URL to download the file into your application.
multiSelect The default value is false, which allows the user to select a single file. true enables the user to select multiple files.
theme The color theme of the button. The default value is blue. Available values are blue and white. Used only with the OneDrive.createOpenButton method.

Example of a pickerOptions object

var pickerOptions = {
  success: function(files) {
    // Handle returned file object(s)
    alert("You picked " + files.values[0].fileName);

  cancel: function() {
      // handle when the user cancels picking a file

  linkType: "webViewLink", // or "downloadLink",
  multiSelect: false // or true

Open files using a button

You can use the Open from OneDrive Button button on your website to start opening files from OneDrive. This code adds a button element to your page. When a user clicks this button, the OneDrive picker starts with the specified pickerOptions, and returns the file(s) the user selected.

To add the Open from OneDrive Button button to your page, configure the pickerOptions and embed the button, like this.

<script type="text/javascript">
  window.onload = function() {
    var pickerOptions = { /* ... */ };
    var pickerButton = OneDrive.createOpenButton(pickerOptions);

<div id="picker"></div>

Note: After the createOpenButton method is called, the pickerOptions object can't be modified.

Start the picker programmatically

If you want to design your own button or start the picker programmatically, use the method, configured with the desired pickerOptions:

<script type="text/javascript">
  function launchOneDrivePicker(){
    var pickerOptions = { /* ... */ };;

<button onclick="launchOneDrivePicker">Open from OneDrive</button>

When the picker starts, it opens a dialog box, prompting the user to select files. Once the user either cancels or finishes selecting file(s), your app receives a response object representing the files they selected.

Handling the picker response with the files object

When the user is done picking file(s), the success callback receives response object which has a values property, which includes is an array of file objects, with length 1 for single select.

  link: "https://...",
  values: [
      fileName: "file.txt",
      link: "https://..."
    { },
    { }

The response object has the following properties:

Property name Value Description
link string - url If the linkType is webViewLink and multiSelect is true, then link will return a webViewLink for viewing all files. If not, then link is null.
values Array of file objects Collection of file objects for each file selected by the user.

Example of a file object

  fileName: "file.txt",
  link: "https://...",
  linkType: "webViewLink",
  size: 123456,
  thumbnails: ["https://...", "https://...", "https://..."]

The file object has the following properties:

Property name Values Description
fileName string Name of the file including its extension.
link string - url URL of the requested file.
linkType string Type of link generated. Either webViewLink or downloadLink.
size integer Size of the file, in bytes.
thumbnails Array of thumbnail urls Array of thumbnail links for image or video files (large, medium, and small, in that order). This value is null for other file types.

Saving files to OneDrive

To start saving files to OneDrive, embed a Save to OneDrive button button directly into your app by using the OneDrive.createSaveButton method, or create a more personalized experience by using the method. Both methods require a saverOptions object with the following parameters.

Note: A user can only save files up to 100 MB using the OneDrive JavaScript saver SDK.

Example of a saverOptions object

var saverOptions = {
  file: "inputFile",
  fileName: 'file.txt',
  success: function(){
    // upload is complete
  progress: function(p) {
    // upload is progressing
  cancel: function(){
    // upload was cancelled
  error: function(e) {
    // an error occured

The saverOptions object has the following properties:

Parameter name Description
file Required. The form input element ID for the file parameter.
fileName If not provided, the file name will be inferred from the name attribute of the input element.
success Called when the file upload to the server is complete.
progress Called at various points with a float between 0.0 and 100.0 to indicate the progress of the upload. This is called at least once with 100.0.
cancel Called when the user cancels the saver.
error Called when an error occurred on the server, the user is out of quota, or the user doesn't have permission to upload to the chosen location.
theme The color theme of the button. The default value is blue. Available values are blue and white. Used only with the OneDrive.createSaveButton method.

Save files to OneDrive by using a button

Much like the Open from OneDrive Button button, you can embed the Save to OneDrive button button with a few lines of code. When a user clicks this button, the OneDrive saver will start and the user can choose a location in their OneDrive to save the file.

<script type="text/javascript">
window.onload = function() {
    var saverOptions = { file: "file" /* ... */ };
    var saverButton = OneDrive.createSaveButton(saverOptions);

<input id="file" name="file" type="file" />
<div id="save"></div>

Note: When the createSaveButton method is called, the saverOptions object cannot be modified.

Start the saver programmatically

You can design your own button or start the OneDrive saver programmatically, by calling the method. It displays a dialog box that asks the user to choose a folder to save the file to. Once the folder is selected, the OneDrive saver uploads the file. Use the method configured with the desired options to launch the saver experience.

<script type="text/javascript">
  function launchOneDriveSaver(){
    var saverOptions = { file: "file" /* ... */ };;

<input id="file" name="file" type="file" />
<button onclick="launchOneDriveSaver">Save to OneDrive</button>

When the saver is started, it launches a popup dialog. After the user chooses a folder to save the file to, the saver is dismissed and the file is uploaded.
