Sending Data 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.

To set up a webhook, go to your web service to 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.

Once these elements are in place, you can immediately send data to a webhook from an Explore, Look, or dashboard using the Send option. This lets you send data right away, without setting up a schedule. In the case of an Explore, you can send a query immediately, without having to save the query to a dashboard or a Look.

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

After choosing Send, choose Webhook in the Where should this data go section. You’ll see the following options:

The following sections explain each setting for sending data to a webhook destination. For a description of all sending options, see the Sending Data Now documentation page.

Naming Your Delivery

Give the content a unique title in the Title 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.

For dashboards, you can choose:

For Looks and Explores, you can choose:

Using Advanced Options

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

Sending Limits

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

If you choose "Results in Table," Looker will obey whatever row limitations you've set up in the saved Look or the Explore. If you choose "All Results," Looker will return all the rows of the query, regardless of any saved Look settings, and regardless of Looker's typical 5,000 row limit. This can be desirable for retrieving very large datasets, but you should use caution to ensure the query is not too large for your database.

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, Explores, 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 Expands tables option, talk to your Looker admin about installing the Chromium renderer for your Looker instance.

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.

Send Your Content

When you have selected all the options for your delivery, click the Send button to send your content.
