# What's new in Sigma

> Sigma release notes for May 8, 2026: Agent skills for Sigma, new API endpoints for managing API credentials and connectors in Sigma, and more.

## AI

### Agent skills for Sigma

You can install agent skills for Sigma to help AI assistants authenticate to the Sigma REST API and create Sigma documents as code.

For more information, as well as access to the public skills repository, see [Install skills for AI assistants](https://help.sigmacomputing.com/docs/install-skills-for-ai-assistants).

## API

### New API endpoints for managing API credentials and connectors in Sigma

The following endpoints are now available to manage API credentials in Sigma:

* [List API credentials](/reference/list-api-credentials) (`GET v2/api-credentials`)
* [Get an API credential](/reference/get-api-credential) (`GET v2/api-credentials/{apiCredentialId}`)
* [Create an API credential](/reference/create-api-credential) (`POST v2/api-credentials`)
* [Update an API credential](/reference/update-api-credential) (`PATCH v2/api-credentials/{apiCredentialId}`)
* [Delete an API credential](/reference/delete-api-credential) (`DELETE v2/api-credentials/{apiCredentialId}`)

The following endpoints are now available to manage API connectors in Sigma:

* [List API connectors](/reference/list-api-connectors) (`GET v2/api-connectors`)
* [Get an API connector](/reference/get-api-connector) (`GET v2/api-connectors/{apiConnectorId}`)
* [Create an API connector](/reference/create-api-connector) (`POST v2/api-connectors`)
* [Update an API connector](/reference/update-api-connector) (`PATCH v2/api-connectors/{apiConnectorId}`)
* [Delete an API connector](/reference/delete-api-connector) (`DELETE v2/api-connectors/{apiConnectorId}`)

## Infrastructure

### Databricks sample connection

The *Sigma Sample Catalog,* a sample Databricks connection, is available to all Sigma organizations upon request. For more information on managing your organization's sample connections, see [Sigma's sample connection](https://help.sigmacomputing.com/docs/sigmas-sample-connection).

## Reports

### Create an action that downloads a report

You can now create a workbook action that downloads an entire report as a PDF.

See [Create actions that send notifications and export data](https://help.sigmacomputing.com/docs/create-actions-that-send-notifications-and-export-data#download-a-report).

## Workbook elements

### Button formatting for action columns

You can format table columns that trigger an action sequence to appear as buttons, highlighting interactivity for users. For more information, see [Format action button columns](https://help.sigmacomputing.com/docs/format-and-customize-a-table#format-action-button-columns).

## Workbook features

### Call API action (GA)

You can create actions that call API endpoints in Sigma workbooks. Using the **Call API** action, you can trigger workflows, enrich data, and interact with external systems without leaving Sigma. For more information, see [Create actions that call API endpoints](https://help.sigmacomputing.com/docs/create-actions-that-call-api-endpoints).

To support the **Call API** action, you can define API credentials and API connectors directly in Sigma, using diverse authentication methods, dynamic query and path parameters, request bodies with typed variables, and more. You can optionally create a connector from an existing OpenAPI specification. See [Configure API credentials and connectors in Sigma](https://help.sigmacomputing.com/docs/configure-api-credentials-and-connectors-in-sigma).

For an interactive, step-by-step experience configuring credentials, connectors, and **Call API** actions, see the following tutorials:

* [Tutorial: Configure API credentials, connectors, and actions for the Sigma REST API](https://help.sigmacomputing.com/docs/tutorial-configure-api-credentials-connectors-and-actions-for-the-sigma-rest-api)
* [Tutorial: Configure API credentials, connectors, and actions for the NYC Open Data API](https://help.sigmacomputing.com/docs/tutorial-configure-api-credentials-connectors-and-actions-for-the-nyc-open-data-api)

### True transparency for element background color

Previously, setting the **Background color** of an element to `None` changed the element background color to match the color of the workbook page or container behind the element. Now, it enables true transparency, allowing you to see page and container background images behind the element.
