Embeddable Analytics

We provide multiple embed options:

Dashboards and widgets can be embedded using using our Javascript API, or using an iFrame.

URL Embed

Simple URL Share and Embed

To generate a public URL for a dashboard, click on 'Generate Shareable URL' from the 'Share' tab of the dashboard.

Note: This makes the dashboard publicly accessible, without requiring a login. Do not use this option for sensitive data.

In addition, the embed code can also be used to embed the dashboard into your own portal/HTML pages.

To turn off a unique public URL, click on 'Disable Share URL'.

To add filter parameters to the share URL, pass in contentFilters parameter to the URL, where the value is in encoded JSON form.

Example: URL Parameter example: contentFilters=[{"fieldName":"opened","values":[1000],"operator":">"}]

Full URL, with the parameter and encoded JSON: 
https://www.knowi.com/d/3cKltxiizxNFgxjRvanZwY2WZoiikPo5ip3EqS13cii1KdQie?contentFilters=%5B%7B%22fieldName%22%3A%22opened%22%2C%22values%22%3A%5B1000%5D%2C%22operator%22%3A%22%3E%22%7D%5D

Secure URL Embed

Use this option to securely embed dashboards where you can filter the data based on parameters that are encrypted (using your customer key). This ensures that the request is not tampered with.

Steps:

  1. Contact us to obtain a customer key.

  2. Use the key to AES encrypt your request parameters. Include contentFilters as a parameter (mandatory).

    Parameters: contentFilters

    Example: contentFilters=[{"fieldName":"opened","values":[1000],"operator":">"}]

    Please contact support@knowi.com for assistance with AES encryption and/or sample code.

  3. Use the Share settings in the dashboard, and click on 'Generate Secure URL' a generate an embeddable URL.

  4. Build the URL with the generated hash at in step 2 at runtime. Embed into an iFrame inside your portal (or use the JavaScript API) Example: https://www.knowi.com/share/secure/VyqOBEBfyKt7ZUzLyH68Vm3lT34NisUIYM1VOis0IpI38ie/{secureHash}

Example Javascript Usage: 

<HEAD>

 <script src="https://www.knowi.com/minify/knowi-api.min.js"></script>

 <!-- *********** Edit here *********** -->

 <script>

 function loadChart() {
     Knowi.render('#knowi-div', {
       type: 'secure',
       hash: "rcf9rdm6zTDd6KIz9EblkO0e0BfEFF0SCjH9RABg=",
       dashboard: "4kjl45kipgqULyXaT5fAUD3ipIypbipPNq2wm6D197pJKCnQnTx",
       view: {
         title: true,
         border: true,
         header: true,
         backgroundColor: "lightblue",
         setting: true
       }
    }, function () {
       });
 }

 </script>

</HEAD>

<BODY onload="loadChart()">

<div id="knowi-div"></div>

</BODY>
</HTML>

Link Expiry

You can also specify a time to expire for a given request, so that the link with the same parameters cannot be reused. To add an expiry, pass in the following two parameters to the request prior to the encryption routine:

Current Epoch Time: _t
Expiry in seconds: _ttl (default is 60 seconds if _t is present without _ttl).

Example url before passing it through the hashing/encryption routine: contentFilters=[{"fieldName":"opened","values":[1000],"operator":">"}]&t=1537661183&ttl=30_

Single Sign-On API

Single Sign-On is an alternative to the above URL based schemes, when you want to fine grained control over users, groups and access rights associated to both.

Flow

  1. Create a user in Knowi and associate to groups via an API. Store the returned token for this user.
  2. Create a session token using the token for the user.
  3. Access the dashboards using the session token.

API details

    userGroups[] no Array of User groups in text form that users will subscribes to.
    Note: Group will be created if it does not exists
    role no role with permissions the user should have. Defaults to user role if blank.
    refresh no Boolean. If True user properties (i.e. userGroups[], contentFilter, role) will be refreshed and updated with new values
    contentFilter no JSON. User's content filters

Returns: - A user specific token. Store this for your user within your system.

  1. Create a Session for a user:

Returns a user token back.

Create Session, using the token for the user:

curl  -i -X POST -d "user=a@a.com&userToken=NUAslkrtRTTFMvscpiislikfyfhsgu491is7plqRvwvJGEgm7JVU8ie" https://www.knowi.com/sso/session/create
Returns a session token.

For added security, Both User creation and session creation also has optional domain matching, where we serve requests from specific hosts.

  1. Access the dashboards : Use the JavaScript API or iFrame the url in the following format: https://www.knowi.com/sso/user/login?token=<session token>

  2. To delete a Single Sign-On User:

    POST:  https://www.knowi.com/sso/user/remove
    Parameter Required? Description
    user yes email of user to remove from account
    userToken yes stored user token associated to user
    ssoCustomerToken yes A customer specific token to authorize user deletion

SSO Embedding 

Option 1: iFrame the URL, with the session token:

https://www.knowi.com/sso/user/login?token=b7E5pofgis9nBjSyPxUclksflkfltS1ZEPhhHhG2MBZis34QJiiBFn8ie

Option 2: Use the JavaScript API: 

Knowi.render('#knowi-div', { 
    type: 'single', 
    token: '...', 
    view: { 
      title: true, 
      css: ['https://rawgit.com/AntonLapshin/csharp/master/custom1.css', 'https://rawgit.com/AntonLapshin/csharp/master/custom2.css'] 
    }, 
   }, 
   function() { alert("Loaded") }
);

User level filters and roles

Create User with user level filters enabled: 

curl  -i -X POST -d "userGroups[]=Default&user=a17@a.com&ssoCustomerToken=9ebdlklfWlYuQXPXanqHxq7ZflklfZ1pGC8Ny8l2is9uNhMie&contentFilter=[{\"fieldName\":\"customer\",\"values\":[\"LinkedIn\"],\"operator\":\"=\"}]" https://www.knowi.com/sso/user/create

Then create the session token and iFrame the URL with the session token like in the example above.

            scroll: false
          }

CSS Customization

You own custom CSS can be injected into the API. Simply specify a comma separated list of CSS files and their full path during the initialization. 

Knowi.render('#cloud9charts', {
    type: 'touchdown',
    username: 'name',
    password: 'pass',
    view: {
      title: true,
      css: ['https://rawgit.com/AntonLapshin/csharp/master/custom1.css', 'https://rawgit.com/AntonLapshin/csharp/master/custom2.css']
    },
}, function() {
    alert("Loaded")
});

See sample JSFiddle.

Filters

To pass in filters:

    Knowi.render('#cloud9charts', {
       type: 'share',
       dashboard: 'CnzzWr6ZGrii4BYsa295HoVWzNB7VaZey6StgO1uFw2kie'
       view: {
         title: true,
         contentFilters: [
            {
               "fieldName":
               "opened",

       alert("Loaded")
    });

Note: Secure URL modes requires contentFilters to be encrypted.

  2. Rotating dashboards sample: Download

Widget Level Embedding

In addition to dashboard level embed options outlined above, you can also share a widget by itself. To generate a shareable URL for a widget, click on 'Generate Shareable URL' from the 'Share' tab of the widget options dropdown.

Note: This makes the widget publicly accessible, without requiring a login. Do not use this option for sensitive data.

To turn off a unique public URL, click on 'Disable Share URL'.

### Embed a widget via the Javascript API

Include the Javascript API:

<script src="//www.knowi.com/minify/knowi-api.min.js"></script>

### Usage

To render Knowi widget on a page, add the following javascript:

  <script>
      Knowi.render('#myDiv', {
        type: 'shareWidget',
        dashboard: 'nZcdj3DThlSDuZhrh6E8KVP9TLZFStoWWAOCGh8zP0cie'
      }, function () {
          alert("Loaded");
      });
  </script>

The content filters also can be passed to widget same as for dashboards.
