# Tasks

This document describes what tasks are, the supported tasks in Application Integration, and how to use them in your integrations.

## Overview


A task is a well-defined unit of work in an integration. In general, tasks can take an input,
complete a unit of work using the input, and produce an output. You can use different types of tasks in your integration to solve a particular business problem. A task is triggered by a [trigger](https://docs.cloud.google.com/application-integration/docs/all-triggers-tasks#triggers) or another task.

For the list of all the available out-of-the-box tasks, see [All triggers and tasks](https://docs.cloud.google.com/application-integration/docs/all-triggers-tasks).

## Tasks

You can add tasks to your integration from the **Tasks** list. You can search, browse, and select the task that you want to add. The following image shows the list of options that appear when you click **Tasks** in the integration editor.

### Connectors

Connectors are a type of task that allow you to connect to an external system or service. You can
use connectors to perform various tasks such as reading data from a database, sending an email, or
making a REST call. You can add a recently created connection or any supported connectors to your integration. For more information about **Connectors task** , see [Connectors task](https://docs.cloud.google.com/application-integration/docs/connectors-task). The following image shows the list of recently created connections and supported connectors that appear in the **Tasks** list.

You can search for connectors, connections, and tasks by entering the name in the **Search** field. The list shows the matching connectors, connections, and tasks. You can select the element that you want to add to your integration.
