Get started with private embedding

Knowledge check:This page assumes you know the basics of Inline Frame <iframe> HTML elements, Uniform Resource Locators (URLs), and third-party cookies. Check out the MDN web documentation on iframes to familiarize yourself with the basics.

This page will walk you through how to set up private embedding. The private embedding option requires that you manage the <iframe> HTML element directly to embed your Looker content and requires that the user log in to Looker separately from the host application.

We will walk through this private embedding code example:

<iframe
    src="https://instance.looker.com/embed/dashboards/4?Timeframe=14+day"
    width="600"
    height="300"
    frameborder="0">
</iframe>

Note: The following directions apply to all embeddable Looker content: dashboards, LookML dashboards, Explores, Looks, query visualizations, and extensions.

1. Build the embed content URL

Note: This page describes how to manually build the embed content URL. You can also generate an embed URL from a Looker dashboard, Look, or Explore.

Let's consider an example of Looker content at the URL https://instance.looker.com/dashboards/4?theme=red&Timeframe=14+day. From this Looker content URL, we will construct the embed content URL and set the iframe's src attribute to it. Feel free to use your own Looker content URL as you work through these steps.

The embed content URL from the preceding code sample is follows:

https://instance.looker.com/embed/dashboards/4?theme=red&Timeframe=14+day

The embed content URL consists of three parts:

• Hostname: your Looker instance's hostname
• Path: Looker content URL path prefixed with /embed (with extra steps for query visualizations)
• Parameters: URL parameters that specify filters and theming

The protocol must always be https://. Let's build each part in detail.

Note: As a shortcut, think of the embed content URL as your complete Looker content URL with embed/ prefixed to its path (unless you're embedding query visualizations noted below).

Part 1: Hostname

1. Navigate to your Looker content. Following the example Looker content URL: https://instance.looker.com/dashboards/4?theme=red&Timeframe=14+day.
2. Your embed content URL hostname is instance.looker.com.

Note: The hostname includes the port number, if present, e.g., instance.looker.com:9999.

Part 2: Path

Your embed content URL path depends on the Looker content you embed.

Embedding all Looker content except query visualizations

1. Navigate to your Looker content. Following the example Looker content URL: https://instance.looker.com/dashboards/4?theme=red&Timeframe=14+day
2. Identify your Looker content URL's path: /dashboards/4.
3. Prefix /embed onto your Looker content URL's path. Your embed content URL's path is /embed/dashboards/4.

Embedding a query visualization

1. Navigate to your query visualization. Example URL: instance.looker.com/explore/my_model/my_explore?qid=1234567890abcdefghij12
2. Identify your query client ID. The qid parameter: 1234567890abcdefghij12 is your query's client ID that represents the query and the visualizations settings.
3. Your embed content URL path is /embed/query-visualization/ appended with your query client ID. The example embed content URL's path is /embed/query-visualization/1234567890abcdefghij12

Note: You can also find the query client ID with the Looker API Get Query method as the client_id field of the Query object.

Part 3: Parameters

Your embed content URL parameters control your embedded content's filters and theming.

Filters

1. Navigate to your Looker content URL.
2. Manually adjust the content's filters to what you desire. For this example, your resulting Looker content URL is: https://instance.looker.com/dashboards/4?Timeframe=14+day
3. Your embed content URL parameters are the Looker content URL parameters, e.g., Timeframe=14+day

In this example, the parameter Timeframe=14+day sets the value of the dashboard's Timeframe filter.

Note: The filter parameter does not create the filter, it must exist on the dashboard beforehand.

Theming

Check out the theming guide to read about how to control the appearance of your embedded content.

2. Test your embed content URL

Open your embed content URL in your browser to preview your embed content's behavior and appearance.

3. Create your iframe

1. Create your iframe element in your host application.
2. Set the src attribute to your embed content URL.
3. Define the width, height, and other attributes to what you need to best display your embedded Looker content.

4. Consider user access issues

The user must be logged in to Looker to view your embedded content. The iframe will show a 401 error page if the user is not logged in.

User login options

Your user can log in to Looker in one of two ways:

1. Log in to Looker beforehand

Your user must log in to Looker on the same browser before they can view the embedded content.

2. Enable an optional embed Looker login screen

Add allow_login_screen=true to your embed content URL parameters to present a Looker login screen in the iframe if the user is not logged in. Our example embed content URL becomes: https://instance_name.looker.com/embed/dashboards/4?Timeframe=14+day&allow_login_screen=true.

Keep in mind two caveats:

• You must disable the Same-Origin Protections for Looker Login Pages setting to enable the Looker login screen in the iframe embed.
• If your Looker instance authenticates users via single sign-on (SSO) with an identity provider, your identity provider may block the login screen within your iframe. You will need to use option 1 if this happens.

User browser cookie policy

Looker uses cookies for user authentication and session storage. Your user's browser must enable third-party cookies if your user accesses your Looker instance embed content url's hostname is under a different domain from your host application.

Some browsers, such as Firefox and Safari, default to a cookie policy that blocks third-party cookies. If the user's browser cannot allow third-party cookies, you can add a custom domain to your Looker instance so your host application and embed content url's hostnameLooker instance reside under the same domain.

Note: You can view a list of the cookies that Looker uses on the Looker cookie list documentation page.

5. Interact with your iframe
