How to Pass the field_selection_filter Field in Looker API

Now that we’ve established the importance of the field_selection_filter field, let’s dive into the nitty-gritty of how to pass it when updating an alert in Looker API.

Using the Looker API Explorer

The Looker API Explorer is a handy tool that allows you to interact with the Looker API directly. To pass the field_selection_filter field using the API Explorer, follow these steps:

1. Log in to your Looker account and navigate to the API Explorer
2. Select the “Update Alert” endpoint and click on the “Try it out” button
3. In the “Request Body” section, add the following JSON payload:

   {
     "alert": {
       "id": "<alert_id>",
       "field_selection_filter": {
         "include": ["field1", "field2"],
         "exclude": ["field3", "field4"]
       }
     }
   }
   

4. Replace <alert_id> with the actual ID of the alert you want to update
5. Customize the include and exclude arrays to specify the fields you want to filter
6. Click the “Execute” button to send the request

Using cURL or a Programming Language

Alternatively, you can use cURL or a programming language like Python or JavaScript to update an alert and pass the field_selection_filter field.

Here’s an example cURL command:

curl -X PATCH \
  https://your-looker-instance.com/api/3.1/alerts/<alert_id> \
  -H 'Content-Type: application/json' \
  -H 'Authorization: Bearer YOUR_API_KEY' \
  -d '{
        "alert": {
          "id": "<alert_id>",
          "field_selection_filter": {
            "include": ["field1", "field2"],
            "exclude": ["field3", "field4"]
          }
        }
      }'

Replace <alert_id> with the actual ID of the alert you want to update, and YOUR_API_KEY with your actual API key.

For programming languages, you can use libraries like requests in Python or axios in JavaScript to send a PATCH request to the Update Alert endpoint.

Tips and Tricks for Using the field_selection_filter Field

Now that you know how to pass the field_selection_filter field, here are some additional tips and tricks to help you get the most out of it:

Use Wildcards

You can use wildcards in the include and exclude arrays to match multiple fields. For example:

"field_selection_filter": {
  "include": ["field1*", "field2_*"],
  "exclude": ["field3_a", "field4_b*"]
}

This will include all fields that start with field1 and all fields that start with field2_, while excluding fields that start with field3_a and fields that start with field4_b.

Combine Multiple Filters

You can combine multiple filters by using the AND and OR operators. For example:

"field_selection_filter": {
  "include": ["field1", "field2"],
  "exclude": ["field3", "field4"],
  "and": [
    {"field": "field5", "value": "abc"},
    {"field": "field6", "value": "def"}
  ]
}

This will include fields field1 and field2, exclude fields field3 and field4, and apply additional filters to fields field5 and field6.

Common Errors and Troubleshooting

When working with the field_selection_filter field, you may encounter some common errors. Here are some troubleshooting tips to help you overcome them:

Error: Invalid JSON Payload

Make sure that your JSON payload is correctly formatted and that you’re using the correct syntax for the field_selection_filter field.

Error: Field Not Found

Verify that the fields you’re trying to include or exclude exist in the alert’s underlying Explore.

Error: Filter Syntax Error
