User Guide – SPFx – Authentication

ATTENTION: Starting with version 2.4.1, we have introduced a new service-based authentication system which enables users to skip the following section. You may still use the system outlined below, however, we recommend using our new system in most cases. Please see the section labeled “NEW: Service-Based Authentication” for more information

Prior to the installation of any other WebParts, the netDocShare Auth WebPart must be installed first. This WebPart is required for security reasons, as your NetDocuments account is secured by login and authentication processes. If the Auth WebPart is not added, the other WebParts will be unable to login to NetDocuments.

Step-by-step installation instructions:

1. Classic SharePoint:

From the Home page in your SharePoint account, navigate to Site Contents on the left-hand side menu. Choose or create a page from within one of your Site Contents’ Lists or Libraries that you wish to add the netDocShare Auth WebPart to.

Note: This page does not have to be the same page as where you wish to install the Document Viewer, RecentDocs, TreeView WebParts. The netDocShare Auth WebPart only needs to exist on a page within the scope of your Root Site Collection in order to facilitate the NetDocuments authentication procedure for any and all the included WebParts.

Classic SharePoint (Team Site):

Select Pages on left-side panel. Create a new Web Part Page.

2. Classic SharePoint:

Click Page in the upper left-hand corner. Next, click Edit Page on the ribbon’s far left.

Classic SharePoint (Team Site):

Name the new web part “auth”*, select Full Page, Vertical, select Site Pages for Document Library, then Create.


3. Classic SharePoint:

Click Add a Web Part. Under the Categories gallery, find and select your SPFx WebParts folder from the menu and select the Auth WebPart. Note: Your category list may look different depending on what you have installed on your SharePoint tenant.

Classic SharePoint (Team Site):

Similar to Classic. Destination for AuthWebPart may vary.

4. You will see that the newly added Web Part says, “Please input your NetDocuments Configuration Object.” Click the Web Part menu (small arrow in the upper right-hand corner) and then select Edit Web Part.

5. Classic SharePoint:

Select Extended Settings at the bottom and enter the App Configuration Auth JSON Object (Example provided in following step) inside the Config Settings field, then click Apply.

Classic SharePoint (Team Site):

At the Configure web part, click “Configure”. Enter the App Configuration Auth JSON Object (Example provided in following step) inside the Enter your Webpart Config here field, then click “x” at top-right and click Apply.

6. An example and explanation of this Auth JSON Object is as follows:


“viewType”: “Auth”,

“netDocsClientId”: “AP-P0V35CC”,

“netDocsClientSecret”: “22neL4s4DF5WU18RMaUX2pikMzg460urwyr2xMCsf”,

“netDocsBaseUrl”: ““,

“CDNBaseUrl”: ” https://klstsp13d-sp:5807/ “,

“authPage”: “redirect”

“AuthSuffix”: “Pages/auth.aspx ”


For explanations of each property, what they do and what values should be used to change them, please see our Config Builder Properties Appendix at the end of the document.

7. Note: The page to which you add the Auth WebPart must be registered with your NetDocuments Developer account ( as a redirect URI. With this method, no matter where your other netDocShare WebParts are, the NetDocuments REST API will always authenticate to the URL where your Auth WebPart exists.
This allows multiple WebParts on the site collection to be authenticated from just 1 location. Without this process, every WebPart page will need to authenticate on its own, requiring you to add every URL to the Dev account. Now that you have a netDocShare Auth WebPart, you may navigate to any other page within the scope of your Root Site Collection and install any of the other netDocShare WebParts using the same process as above. More info about this in the next section.

8. Once the Auth process activates, a popup will be opened with a NetDocuments login screen similar to this:

Enter your NetDocuments credentials. It should recognize that the login is coming from a custom app instead of a general browser login. It will then ask for permissions for this specific app on a screen that looks like this:

Note the name of the app, which should match the name of the App created in your account

You must click ‘Allow’ for the app to work but you do NOT have to do it during the process of setting up Auth for the first time. When in initial setup, all you need to do is make sure that the app name, redirect URL and login details on the top right are correct. You may press escape to cancel the popup and save the webpart page to continue.

Note: When making the Auth page for the first time, once you have determined that the configs are correct, simply save the page. You may notice that if you press “Allow” in this initial state, it may redirect you to an empty or blank page. This is because the Auth webpart is designed to be used as a part of the authorization process, in which it will re-direct users back to the original requesting page after authorizing. This will not work if you do not have other webparts created yet.

Classic vs Modern:

This process is very similar for modern pages except for aesthetics. Add a page by navigating to Pages, which should be a tab link in the homepage of the site collection.

From here you can simply create a new page and use the edit buttons that you see on the page instead of the ribbon. In edit mode, press the + button to add a new WebPart.

This list should already be populated with the WebParts you need, if you have deployed correctly

To configure or update the WebPart, simply use the Edit (pencil symbol) which will bring up a properties pane on the right side of the screen.

The process of authenticating with NetDocuments requires some steps in your NetDocuments administration account. This can be reached through

In order to obtain the netDocsClientId and netDocsClientSecret (required for each webpart), you must create an “app” on You should be lead to the following screen:

Fill in the required fields and make sure to keep track of 2 important things:

Once you save, your Client Id and Client Secret will be generated. Please keep track of them as they will be required in every webpart’s config.

Redirect URI and Additional Redirect URIs will be very important once you have begun to create webparts. Every environment requires a distinct Redirect URI which is used to redirect you back to your source after executing standard Oauth authentication procedures. Each distinct environment must have its own authentication page

You must include every redirect URI that you are planning to use into this list or else the authentication will return Invalid Redirect URI errors. Note that the RedirectURIs are very case sensitive.

Once the Auth webpart is created, you can create another webpart which will retrieve data, on a page such as:


Now, the full authentication cycle should be complete. Let’s see an example of how it works using our example pages:

User visits the documentView.aspx page in order to see their documents

A request to the NetDocuments API will require an access token, if there is no token, the app will bring up the auth.aspx page as a popup**.

The Auth page will use existing info OR ask the user to login and an authorization request is sent to NetDocuments with the auth.aspx page as a redirect

NetDocuments sends an authorization code which brings up the “Allow / Deny” dialog.

Once “Allow” is pressed, NetDocuments will send a refresh token and an access token. Congratulations! Authentication is complete and the user will be taken back to documentView.aspx where they can view any number of documents until the token expires

** Users have the option to choose between 2 Authentication styles that we offer: iFrame or redirect. We recommend iFrame as it is a smoother user experience, in that it is a 2-step process instead of a 3-step process. However, we offer the second option as some client environments may block iFrame windows for security reasons.

With ‘iFrame’, the webpart will open a modal iFrame window popup which will contain the Login or Allow / Deny pages served by NetDocuments. Then, it will refresh the original page with the new credentials active.

With ‘redirect’, the webpart will change the current page’s url to manually navigate to the Login or Allow / Deny pages served by NetDocuments. Then, it will redirect back to the user’s set up Auth page and from there, they will be redirected a 3rd time back to the original page which requested the permissions.

Access tokens have a limited lifespan. They expire after 60 minutes of no activity or between 24 and 48 hours of when they are issued. If an API is made with an expired token, a 401 Unauthorized status is returned. netDocShare automatically processes expired tokens and attempts to retrieve a new token when required. For this, we use refresh tokens which last much longer.

With the new OAuth implementation, the refresh token with full access will expire in 40 days rather than 1 year. A refresh token with the least access will expire after 90 days. Once the refresh token has been depleted, users will be expected to enter their login credentials again in order to obtain a new refresh token.

This is different from a login lifetime when using NetDocuments itself. NetDocuments for security reasons will log out users automatically after 90 minutes of inactivity. As a NetDocuments user, you can enable an automated login option if your organization has Microsoft Active Directory Services.

Logging out from NetDocuments can be done on a browser level. For example, if you log in to in a browser tab and open a SharePoint page with netDocShare webparts in another tab, it will recognize that you are logged in and display the Allow / Deny screen.

We also provide an optional method to log out from inside NetDocShare. The Config Builder contains a field called “Show Logout”. When enabled, this will include a dropdown menu on the top right side of the webpart which will display a greeting and the NetDocuments user’s name:

Clicking on this will reveal a logout option which will remove the NetDocuments session from the browser. Note: This will log you out of NetDocuments in every tab of the current browser. The page will refresh automatically, and users must login to NetDocuments before resuming usage.

Invalid URL error

Users must make sure that the URL they submit to is EXACTLY the same as their auth page URL. This must match case and spelling exactly or else it will throw invalid URL error. This includes http and https.

Duplicate Webparts

In some older SharePoint versions, webparts linger on the page even after they have been deleted. The number of webparts can be seen here:

If there is more than one webpart on a page, it will impact how our software will function, e.g. the page might have multiple auth popups among other things, as the hidden webparts will still be loading code. To remove the unnecessary webparts officially, open the page in Web Part Page Maintenance and remove hidden webparts.

Auth failing to refresh or redirect

If Authentication is failing to redirect or failing to reload the page after logging in or clicking the “Allow / Deny” prompt, this may be due to existing errors on the page which may block attempts to navigate to another page. In order to avoid this, or to test whether this is the issue, please insert our webpart on a blank Sharepoint page that loads no other content such as ScriptEditor webparts or scripts embedded into the Master Page. If the webpart can work on the blank page but not on the original page, there is some content that is blocking the functionality of our app. In this case, we recommend fixing the existing errors on the page or using a page which does not load the problematic content.
