Embeddable Analytics
Knowi makes it easier to create and embed analytics and visualizations into other business applications including your own and into cloud applications like Shopify or Salesforce.
Multiple options are available for embedding:
- Public Embedding
- Token based embedding
- Authenticated Embedding through Single Single On
Embedding offers the ability to customize the user experience of dashboard interaction and functionality of the embedded applications. We provide multiple embed options:
- Simple URL based embedding.
- Secure URL Embed with encrypted request payload.
- Single SignOn API that enables token exchange from users in your system to map to Knowi with user rights & permissions.
Dashboards and widgets can be embedded using using our Javascript API, or using an iFrame.
Getting Started
Knowi's embedded solution allows you to add the power of interactive visualization to external websites and applications. Knowi offers built-in features to distribute live dashboards with a customizable, tailored experience using a Javascript API and the security of Single Sign-On.
Embedding can be a single dashboard or visualization to the full application with integration to handle authentication, personalization, and content management.
Key concepts
Javascript API: API for embedding and programmatically managing the interaction and experience. Ideal for integrating with the functionality of the embedding application
Secure Hash: For public embedding, URL parameters such as user filters can be encrypted.
Authenticated Access: Method to guarantee security and governance for embedded views through Single Sign-On. If users of your application sign in, they will be allowed a passthrough to access Knowi content using the same credentials. Removes the friction of prompting a Knowi login screen.
User Filtering: Ability to securely filter a dashboard's data based on the Knowi login information. This is ideal in multi-tenant scenarios if you have a single dataset or database for multiple users or groups of users. Applying a user filter provides the functionality of utilizing the same content and style across users whilst ensuring each user can see only the rows governed by their user filter
URL Embed
Simple URL Share and Embed
Use this option if you'd like to share or embed a dashboard for public access without security. 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:
Contact us to obtain a customer key.
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.
Use the Share settings in the dashboard, and click on 'Generate Secure URL' a generate an embeddable URL.
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
In some scenarios, you want to guarantee the authentication of users before viewing Knowi content. Single sign-on enables the users signed into your application to view a protected-private Knowi resource without the need of signing in once again on Knowi. Afterward, a new browser session and cookie will be issued to the browser.
User identity, permissions, access level, and attributes are all constructed within the browser session of the single sign-on user, which is created using a unique customer token. Anyone with access to the customer token may create an SSO user to which that Knowi instance is connected to, as any user, with any permission. See our example code to learn how to generate an SSO flow.
Generating Knowi Customer Token:
In order to create and manage SSO users, you'll first need a Knowi SSO Customer Token.
On the left hand side menu, click User Settings --> Account Settings tab. From the Customer Settings section, select ?Generate? in the SSO Token field .
Protect the Knowi SSO Token as you would any credentials to your Knowi instance and keep SSO Token section disabled if you?re not using it.
Note: Contact support@knowi.com if the SSO TOKEN option is not available in your Knowi Customer Settings.
Getting Started: Embedding with SSO requires some code writing to seamlessly integrate into your web application. You can find several example scripts on our SSO examples GitHub repository.
The following simplifies the information needed to embed with SSO.
User Token: Create an SSO user within your account using your Knowi SSO Customer Token
curl -i -X POST -d "user=email@domain.com&ssoCustomerToken=<SSO_TOKEN>" https://www.knowi.com/sso/user/create
Additional parameters can passed when generating a creating an SSO user token, such as assignment to groups, roles/permission, user filters. See the API reference for usage.
Session Token: Create a new session token using the returned token from step 1
curl -i -X POST -d "user=email@domain.com&userToken=<USER_TOKEN>" https://knowi.com/sso/session/createEmbed: Write a Javascript section with the session token returned from step 2
function loadKnowiUser() { Knowi.render('#knowi-div', { type: "single", token: "BYhXXCeu0Ego8zA1FqtLOOM4BDWot5AYBLI7PWrQTbsie", url: "https://www.knowi.com/", view: { title: true, header: true } }, function () { }); }
Note: Alternatively, you can log in directly on a browser or iFrame the URL using the session token returned from step 2
https://www.knowi.com/sso/user/login?token=<SESSION_TOKEN>

To delete a Single Sign-On User:
POST: https://www.knowi.com/sso/user/removeParameter 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.

Search Based Analytics API
The Search Based Analytics API lets you + Develop applications to list query suggestions and retrieve the associated response from the query. + Embed a Google Search like interface to enable plain english requests to search across datasets within a given user's account.
Using Knowi's Search Analytics empowers your end-users the ability to ask questions of their data in English. Think of this as a Google search on your datasets. This functionality can be embedded in your application through Single Sign-On. Try it out.
Similar to embedding with SSO and the Javascript API, the steps to embedding Search Analytics is almost identical and can be achieved in three steps:
1. User Token: Create a Knowi user token for a new or existing user
curl -i -X POST -d "user=email@domain.com&ssoCustomerToken=<SSO_TOKEN>" https://knowi.com/sso/user/create
2. Session Token: Create a Knowi session token with the user token from step 1
curl -i -X POST -d "user=email@domain.com&userToken=<USER_TOKEN>" https://knowi.com/sso/session/create
3. Embed: Write a Javascript file with the session token returned from step 2
function loadSearchAnalytics() {
Knowi.render('#knowi-div', {
type: 'nlp',
token: "BYhXXCeu0Ego8zA1FqtLOOM4BDWot5AYBLI7PWrQTbsie",
url: 'https://www.knowi.com',
view: {
nlpOptions: {
icon: "off",
css: {
background: 'transparent'
},
placeholder: "Try: total sales for canada this week",
}
}
}, function () {
});
}
Note: For embedding Search Analytics, type must be nlp
Following API's mmy be used to create your own search bar. Here are the relevant API calls:
GET: /sso/nlp/suggestions
| Parameter | Required? | Description |
|---|---|---|
| token | yes | SSO session token |
| query | yes | Query to process |
Returns: - A list of suggestions as json array
POST: /sso/nlp/parse
| Parameter | Required? | Description |
|---|---|---|
| token | yes | SSO session token |
| query | yes | Query to process |
| datasetId | yes | Dataset ID that your query should point to |
| format | no | Format of the response (json, txt). Defaults to json |
Returns: - Data as json or txt array

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",
"values":[1000],
"operator":">"
},
{
"fieldName":"message_type",
"values":["marketing"],
"operator":"="
}
]
},
}, function() {
alert("Loaded")
});
Note: Secure URL modes requires contentFilters to be encrypted.
Samples
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.
