Workday RaaS Explained: Reporting as a Service - A Complete Guide

We’ve all been there. The weekly reporting dance.

You log into Workday, navigate to that one specific report, wait for it to run, export it to Excel, and then spend 20 minutes copy-pasting data into your master spreadsheet. Or worse, you’re an analyst waiting on a 2-week IT ticket just to get a CSV dump of employee data.

That’s insane.

In 2026, manual data exports cannot still be the default. If you are building modern data pipelines, you need data that flows automatically, securely, and instantly.

One of the best ways to achieve this is with Workday RaaS (Reporting as a Service). It’s Workday’s latest data feature that turns your Workday tenant into a data powerhouse.

What is Workday RaaS?

Workday RaaS is a feature that allows you to expose any Custom Report as a web service.

In plain English: It turns your report into an API endpoint.

Instead of clicking “Export to Excel,” you get a URL. When you hit that URL, Workday runs the report in real-time and sends back the data in a machine-readable format like JSON, XML, or CSV.

This means you can connect Workday directly to your data warehouse, your BI tools, or your custom applications without writing complex ERP integrations or dealing with Workday Studio.

How to Set Up Workday RaaS

Setting this up is surprisingly straightforward. Here is the step-by-step guide to turning a report into an API.

1. Create an Advanced Custom Report

RaaS only works with Advanced custom reports. Standard reports won’t cut it.

1. Search for “Create Custom Report” in Workday.
2. Give your report a name.
3. Crucial Step: Select “Advanced” as the Report Type.
4. Check the box for “Enable As Web Service”.
5. Uncheck “Optimized for Performance” if you want to use features like sorting or complex calculated fields (though keeping it checked is better for speed if you don’t need those).

2. Define Your Data Fields

Add the fields you need just like any other report.

Pro Tip: Navigate to the “XML Alias” column for each field. The names you put here will become the “keys” in your JSON or XML output.

• Instead of legalName_Last_Name, use lastName.
• Instead of location_Primary, use location.

Your future self will thank you for clean, readable data keys.

3. Configure Filters and Prompts

If you want to filter data dynamically (e.g., “give me all employees hired in the last 7 days”), you need to set up Prompts.

1. Go to the Filter tab and add your logic (e.g., Hire_Date >= Prompt).
2. Go to the Prompts tab.
3. Important: Check “Populate Undefined Prompt Defaults”. This ensures the API call doesn’t fail if you forget a parameter, falling back to a default you define.

4. Set Up Security

You do NOT want to use your personal user account for API integrations. If you leave the company or change your password, the integration breaks.

1. Create an Integration System User (ISU). This is a “robot” account dedicated to this task.
2. Create an Integration System Security Group (ISSG) and add your ISU to it.
3. Grant the ISSG access to the Domain that secures the report’s data source (e.g., “Worker Data: Active”).
4. Share the Report with the authorized ISSG via the “Share” tab on the report definition.

5. Get Your URL

Now for the fun part.

1. View your custom report.
2. Click the Related Actions (the three dots) next to the report name.
3. Hover over Web Service > View URLs.
4. Workday will generate URLs for various formats.
5. Right-click and copy the JSON (WWS) link. JSON is the language of the modern web. Ignore RSS and GData unless you are living in 2010.

It will look something like this: https://wd2-impl-services1.workday.com/ccx/service/customreport2/tenant_name/username/Report_Name?format=json

Best Practices & Gotchas

I’ve seen a lot of RaaS implementations go wrong. Here is how to avoid the headaches.

The Pagination Problem

Workday RaaS does not support pagination by default. If your report returns 100,000 rows, Workday tries to generate one massive JSON file. This will likely timeout or fail.

The Fix: You currently have to build “pseudo-pagination” using prompt parameters (like Date_Entered ranges) to chunk the data yourself. It’s annoying, but necessary for large datasets.

Don’t Be That Person

Just because you can run a report every minute doesn’t mean you should. RaaS reports consume tenant resources. If you hammer the API with complex reports, you might slow down Workday for everyone else logging in to check their paystubs.

• Cache data where possible.
• Use incremental loads (only fetch records changed since the last run).

Handle Errors Gracefully

APIs fail. Workday goes down for maintenance. Your script should retry on 500 errors and alert you if the schema changes (e.g., someone renames a field in the report).

Frequently Asked Questions (FAQ)

Is Workday RaaS free?

Yes, RaaS is included with your standard Workday subscription. You do not need to purchase additional SKU licenses to use it, unlike some other integration tools.

What is the limit for Workday RaaS?

Workday enforces a timeout limit (usually 30 minutes) and memory constraints. For very large datasets (over 50k rows), you must use pagination or the WQL (Workday Query Language) API instead.

RaaS vs. Workday Studio: Which should I use?

Use RaaS for reading data (getting data out). It is faster, easier to maintain, and requires less technical skill. Use Workday Studio for complex bi-directional integrations where you need to write data back into Workday or handle complex logic transformations.

The Easy Way

If manually managing ISUs, security groups, pagination logic, and API error handling sounds like a massive pain… well, it is.

That’s why we built Go Fig.

Go Fig connects to your Workday instance, handles all the complexity around maniuplating data and building reports. It gives you access to the data in a familiar Excel-like PivotTable interface that Finance leaders and Executives will love. We handle the pagination, the incremental syncing, and the schema mapping so you can just focus on the insights.
