Workday - How do I pull in additional fields from my Workday account?
Overview
This article will walk you through creating an Integration System with a Field Override Service in your Workday instance. This process allows your integration to retrieve additional fields, including standard Workday fields and calculated fields.
Prerequisites
You should only begin the process below once you've identified the field (standard or calculated) that you want to pull. If you have not yet created a calculated field and need assistance, refer to the below guide.
Instructions
Step 1: Create the Integration System and Field Override Service
If you already have an Integration System set up in Workday to filter the employees being synced, add your additional fields to that same system rather than creating a new one. Only one Integration System can be used.
Search and select the Create Integration System task in your Workday instance
Give your Integration System a name, ensure that the template is Core Connector: Worker, and select OK.
Ensure that the Template is: Core Connector: Worker
The name doesn't matter, but we suggest a naming convention that you will remember!

After clicking OK, as Configure Integration Services pop-up will appear. Scroll down to the bottom, and add a Custom Integration Services record.

Under the Integration Service column of the newly created row, search for and select Create Integration Field Override Service.

In the Create Integration Field Override Service pop-up, give the Field Override Service a name and select the Worker Business Object
We suggest something like "INT_"

In the Fields section, add the names of all the fields you will be adding to the integration, then select OK.
Note: The name you enter for each field here becomes the key used to identify that field's value in the Workday API response.

You will be taken back to the Configure Integration Services pop-up. Finish the initial creation of the Integration System by selecting OK
On the Integration System page, navigate to Integration System > Configure Integration Field Overrides

Find the name of your Field Override Service on the left side of the page, configure your field overrides, and select OK

Step 2: Find the Integration System ID
Back on the Integration System page, navigate to the Integration IDs > View IDs
Note, if you've navigated away from the Integration System, you can find it again through the View Integration System task

Copy and use the ID value of the Integration System you created
If you just want to pull in these additional fields, you're done! If you also want to filter data by one of the fields, continue on below

Step 3: Input the Integration System ID in Merge Link
Once you have the ID, head back to the linking flow and enter in the filter settings as shown below.
