# Workday REST authentication

> To create a connection to the Workday REST connector, you need the following credentials:

## Prerequisites

To create a connection to the Workday REST connector, you need the following credentials:

* REST API Endpoint
* Authorization URL
* Token URL
* Client ID
* Client secret
* Your Workday username and password.

## How to configure an OAuth API client in Workday

The Workday REST connector is based on the [Workday REST API](https://doc.workday.com/reader/wsiU0cnNjCc_k7shLNxLEA/HvgwLwxCHVdBlZUTNd9s7A).

You must create an API client or use an existing API client for your integration.

To check existing API clients, navigate to the **View API Clients** tab in your Workday dashboard. This is where you can retrieve the required credentials: the REST API Endpoint, Authorization URL, and Token URL.

To create a new API client, follow these steps:

1. Sign in to the Workday portal.
2. Using the search bar, find the **Register API Client** task.

3. Configure the new API client details. First, set a **Client Name**. Choose one that is easily distinguishable from others you may already have.
4. Set **Client Grant type** to **Authorization Code Grant**.
5. Set **Access Token** to **Bearer**.
6. Set the **Redirection URI** to `https://{yourDomain}/provisioning_/callback`.
7. Enable the **Non-Expiring Refresh Tokens** option.
8. In the **Scopes (Functional Areas)** field, add the permissions required for the processes you want to create.
   * For WQL operations, you must select the **System - Workday Query Language** scope.
   * The [HTTP Request](https://docs.uipath.com/activities/other/latest/integration-service/http-request-activity) activity allows you to call any Workday REST API as long as you set the necessary permissions using the **Scope** field.
9. The **Include Workday Owned Scope** field is optional. It grants access to API scopes that are owned and managed by Workday itself. When you enable this option, the API client can interact with more proprietary or system-level functionalities.
10. Once you create the new client, copy and save the client ID and client Secret. You will use them when you create a connection to the UiPath Workday REST connector.

## Add the Workday REST connection

1. Select Integration Service from the left rail.
2. From the **Connectors** list, select Workday REST. You can also use the search bar to narrow down the connector.
3. Select the **Connect to Workday REST** button.
4. Enter your required credentials and select **Connect**.
5. You are then prompted to sign in to Workday with your username and password.
