Scheduling Deliveries Using Webhooks

Webhooks are a modern, increasingly common way to trigger exchanges between internet-based services. With a web service like Zapier, webhooks can let Looker data be delivered to a wide range of applications; for example, you may be able to schedule periodic delivery of a Look or dashboard to a webhook. When you set up a delivery, Looker will prompt you for the webhook address.

Depending on how your Looker admin has configured your permissions, the default delivery destination may be email, and this setting may not be visible.

Setting Up a Webhook

To set up a webhook, go to your web service and do the following:

The exact procedure differs depending on what web service and destination application you’re using to deliver the data. See this Community topic for guidelines on setting up another application to receive the webhook data from Looker.

Looker will attempt delivery to a webhook for a maximum of 30 minutes. Ensure that the destination can respond within 30 minutes to the webhook delivery attempt.

Creating and Editing Schedules

After starting a schedule, Looker displays a dialog box with your scheduling choices. Here is an example Schedule dialog box for a dashboard:

The following sections explain each scheduling setting for a webhook destination. For a description of all scheduling options, see the main scheduling documentation page.

Naming Your Delivery

Give the content a unique title in the Give your schedule a name field. The title is included in the webhook payload under the Title field.

Delivering to Webhook

In Where should this data go, choose Webhook. In the Webhook URL section, enter the URL where Looker should send an HTTPS request for this delivery. You can obtain this URL from the web service you're using to handle your webhook.

Formatting the Data

In Format data as, choose the format for the data in your delivery.

If you do not see all of these format options, talk to your admin about installing the Chromium renderer.

For dashboards, you can choose:

Applying Filters to the Delivery

If you are delivering a Look or dashboard that has filters, you can filter the results delivered to each set of recipients. For example, you might send regional teams results that are filtered for their states of interest:

Click Filters to see and modify the filters associated with this Look or dashboard for your data delivery. Changing these filter options in the Send or Schedule window does not change the filters in your Look or dashboard.

If you change field names that serve as filters in your Looks or dashboards, be sure to review the Filters section of your scheduled Looks and dashboards and update the filters as needed to reflect your changes. If a scheduled content delivery includes filters that no longer function (for example, if the referenced field has changed), the scheduled delivery could expose unfiltered data.

To make custom deliveries even easier, you can use the matches a user attribute filter option if your Looker admins have configured user-specific values called user attributes. Setting a filter to one of these attributes automatically customizes the results for each user, meaning that you can send customized results to many users even if you select Send only once. You can read more about user attributes here.

Using Advanced Options for Webhooks

The Advanced options section provides additional customization for your schedule. Click the arrow next to Advanced options to expand this menu.

Scheduling Conditions

For all Look formats other than JSON—Detailed, Inline, you can add conditions for when the data will be delivered:

Scheduling Limits

When scheduling Looks, you can limit the size of your delivery. Select one of the following limit options for your data:

Streaming Query Results

Streaming refers to Looker's ability to process data in chunks, rather than all at once. If Looker can stream a result set, then unlimited downloads are possible and you can send All Results. In addition to the format requirements mentioned above, there are two cases where streaming is not possible:

  1. Table Calculations: Table calculations cannot be streamed. Therefore, to download unlimited results for a query, you must remove table calculations from the query.
  2. Database Limitations: Some databases cannot stream if pivots are included in the query. For these databases, you must remove pivots to download unlimited results. Some databases can't stream any results, which means that unlimited downloads are not possible. Below is a list of what databases support streaming, as well as databases that support streaming with pivots applied:

Format Options

Apply Visualization Options

For Looks, Explores, and CSV-formatted dashboards, you can configure whether you want the data delivery to use the same options as your visualization:

Formatted Data Values

For Looks and the CSV format of dashboards, you can configure the data's formatting:

Single Column Layout

For dashboard deliveries in PDF or Visualization format, you have the option to print your PDF in a single column layout, which displays dashboard tiles in a single vertical column. Check the Use single column layout box to use this option, or leave the box unchecked to show the tiles as they are arranged in the dashboard.

Expand Tables

To display all rows of a data table — rather than just those rows that display in the dashboard tile thumbnail — in a PDF dashboard delivery or download, check the Expand tables box. If you do not see the Expand tables option, talk to your Looker admin about installing the Chromium renderer for your Looker instance.


By default, Looker will use the time zone associated with your account to determine when to send your data delivery. If you don't have a time zone associated with your account, Looker will use your Application time zone. If you want to specify a different time zone, select Use custom timezone. The time zone you select does not affect the data in your Look or dashboard, just the timing of the delivery.

Paper Size

You have the option to specify the optimal size and orientation of dashboard PDFs by selecting from the Paper size drop-down menu. Large visualizations or groups of overlapping dashboard tiles may need to be resized to fit cleanly on a PDF page. If you do not see the Paper size option, talk to your Looker admin about installing the Chromium renderer for your Looker instance.

Other Scheduling Options

To learn more about other types of data delivery, see the page for each destination option: email, Amazon S3 bucket, SFTP, or one of several integrated services.
