# Step outputs reference

Abstract

Step outputs are environment items that are the result of running a given Step. You can check out the default outputs of a Step in the Workflow Editor on bitrise.io or in the step.yml file of the Step.

Step outputs are environment items that are the result of running a given Step. For example, the Deploy to Bitrise.io Step generates two output envs by default:

• \$BITRISE_PUBLIC_INSTALL_PAGE_URL

• BITRISE_PUBLIC_INSTALL_PAGE_URL_MAP

You can check out the default outputs of a Step in the Workflow Editor on bitrise.io or in the step.yml file of the Step.

Step outputs can be defined in the step.yml file of the project by setting the outputs attribute. They have the same syntax as every environment property. It consists of two main parts: a KEY: value pair and an opts field. The key and the value are required, the opts field is optional.

- MY_KEY_FOR_THE_ENV: my value for the env
opts:
title: An example env var item
is_dont_change_value: false
category: example
• MY_KEY_FOR_THE_ENV: The key of the environment item (required).

• my value for the env: The value of the item (required).

• opts: Optional attributes.

The default outputs of a Step cannot be changed by the user in the bitrise.yml file of the project: they can only be changed in the step.yml file. However, you can export the output in a custom Environment Variable. This is useful, for example, if you have the same step twice in your Workflow and you wish to use the generated output of both steps:

workflows:
primary:
steps:

In this example, the value for the BITRISE_APK_PATH Environment Variable will be exported under the ALIAS_APK_PATH key.
