# Task 1: Configure Your Environment

The environment configuration endpoints perform the following actions:

* Update (or create) an application.

* Specify the application's resource grant.

* Specify a sign-on policy and define its actions.

* Define external identity providers.

This workflow uses an OIDC Web application with the application's `type` property set to `WEB_APP`. The Postman collection for this flow references the Web application that you created in *Getting Started*, Task 3.

## What you'll do

The application configuration in the Postman collections is a PUT call to modify the `grantTypes` property. Run the PUT call to add the `REFRESH_TOKEN` grant type to the application configuration.

|   | If you choose to use an alternate application, be aware that the variables in the Postman collections point to the Task 3 application's ID. You must change references to the application ID manually either in your Postman environment or in the endpoint's URL or request body to run the request. |
