We provide multiple embed options:
Dashboards and widgets can be embedded using using our Javascript API, or using an iFrame.
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
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://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>
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 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.
User Creation:
POST https://api.cloud9charts.com/sso/user/create
Parameters:
user: name of the user in your system to create a Single Sign-On for.
userGroups[]: Array of User groups in text form. User groups are groups that the user subscribes to.
ssoCustomerToken: A customer specific token to authorize user creation. Please contact us to obtain your customer specific token.
contentFilter: Optional. A JSON string to force filter dashboards with given parameters for the user. See example section for further details.
role: Optional. Determines the level of functionality available to this user. admin: Enables full admin rights, including creating and managing new users. user: Default. No User management rights, but can create their own datasources and queries, as well as access to the dashboards and widgets (as well as creating their own). viewer: View-only rights to the dashboards they are allowed to see.
Returns:
A user specific token. Store this for your user within your system.
Create a Session for a user:
POST https://api.cloud9charts.com/sso/session/create
Parameters:
user: name of the user in your system
userToken: Token for this user generated during the user creation process
Returns:
A session Id/token
For added security, Both User creation and session creation also has optional domain matching, where we serve requests from specific hosts.
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>
To delete a Single Sign-On User:
POST: https://api.cloud9charts.com/sso/user/remove
Parameters:
user: name of the user to remove.
userToken: Stored token associated to the user.
Example using curl:
Create User:
curl -i -X POST -d "userGroups[]=First Group&userGroups[]=Second Group&user=a@a.com&ssoCustomerToken=9ebdlklfWlYuQXPXanqHxq7ZflklfZ1pGC8Ny8l2is9uNhMie" https://api.cloud9charts.com/sso/user/create
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://api.cloud9charts.com/sso/session/create
Returns a session token.
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") }
);
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://api.cloud9charts.com/sso/user/create
Then create the session token and iFrame the URL with the session token like in the example above.
More on User level filters here.
To update user level filters, use the following end point:
POST: https://api.cloud9charts.com/sso/user/contentfilters/update
Parameters:
user: name of the user to remove.
userToken: Stored token associated to the user.
Example:
curl -i -X POST -d "user=demoSSO@knowi.com&userToken=7Yx2UAnr2aq6AK66vML2YnisDuZm1BkdNGsBntYO38BUie&contentFilter=[{\"fieldName\":\"customer\",\"values\":[\"Costco\"],\"operator\":\"=\"}]" https://api.cloud9charts.com/sso/user/contentfilters/update
The following end points can be used to retrieve groups, dashboards, queries and widgets:
GET /sso/dashboards
Parameters: token. SSO session token. Required.
Returns: Returns a list of dashboards and details for each dashboard in JSON Array form
Example: curl -i -X GET https://api.cloud9charts.com/sso/dashboards?token="9sBRdisBevkFvfIbb3HnipqjutS00JIjWpTcGKUPe2wMAie"
GET /sso/widgets:
Parameters: token. SSO session token. Required.

GET /sso/groups:
Parameters: token. SSO session token. Required.
Returns: Returns a JSON list of user groups associated to the user
The JavaScript API is an alternative approach to the iFrame embed method.
See a JSFiddle demo of the Javascript API.
Include the Javascript API:
<script src="//knowi.com/minify/knowi-api.min.js"></script>
To render Knowi dashboard on a page, add the following javascript:
<script>
Knowi.render('#myDiv', {
type: 'share',
dashboard: 'CnzzWr6ZGrii4BYsa295HoVWzNB7VaZey6StgO1uFw2kie'
}, function () {
alert("Loaded");
});
</script>
| Option | Comments |
|---|---|
| type | Type of access to dashboard or widget. Supported values: 'share', 'secure', 'single', 'shareWidget' and 'shareWidgetSecure' |
| dashboard | URL of the dashboard or widget. This can be obtained from the Share URL textbox from the dashboard/widget share window. Applicable for 'share', 'secure', 'shareWidget' and 'shareWidgetSecure' types |
| dashboardId | ID of the dashboard or widget. Alternative to the URL method. This can only used in tandem with single sign on, after the user has been authenticated separately. |
| hash | Hash of the 'secure' shared dashboard or widget. Only applicable for 'secure' and 'shareWidgetSecure' types. This is the AES encrypted hash based on your key |
| token | Authorization token for single signon API requests. Used only for 'single' type |
| view | Display properties. Full list of the properties and default values:
title: false
filter: false
autoHeight: false (auto adjusts the height of the dashboard to the div)
border: false
setting: false
resize: false
menu: false
actions: false (determines whether the filter and reset icons are displayed)
drag: false
header: false
scroll: true
css: none (array of urls)
url: none (url to hit for on-premise deployments)
backgroundColor: none (transparent, white, blue, fff, cacaca)
contentFilters: none (array of filters, only applicable for share & single types)
You can override these properties, for example:
|
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.
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.
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="//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.
