Why integrate with Workday
Common scenarios for SaaS companies building Workday integrations for their customers.
Sync the enterprise org chart into your product automatically
If you sell to large enterprises, their HR teams expect your app to reflect real-time reporting lines, departments, and locations without manual CSV imports. Pulling Worker and Supervisory Organization data from Workday lets you keep your product's user directory accurate as people are hired, promoted, or offboarded.
Trigger automated workflows on employee lifecycle events
SaaS platforms in IT security, identity governance, or asset management need to act the moment an employee is hired or terminated in Workday. Polling for status changes lets you fire downstream actions — like provisioning accounts on hire or revoking access on termination — without any manual intervention from the customer's IT team.
Write hired candidate data back into Workday from your ATS
Applicant tracking and recruiting platforms need to pass candidate information into Workday to kick off the onboarding business process. Without this write-back, HR teams are forced into dual data entry, which is a dealbreaker for enterprise buyers evaluating your product.
Route approvals and tag expenses using Workday's cost center and manager hierarchy
Travel, expense, and procurement SaaS products need to know each employee's manager and cost center to enforce approval chains and financial coding. Importing this structure from Workday ensures compliance and eliminates manual configuration by finance teams.
Unblock enterprise deals that require a native Workday integration
For many Fortune 500 procurement processes, a working Workday integration is a hard requirement on the vendor checklist. Offering it as a native capability — rather than asking the customer to build middleware — removes friction from the sales cycle and accelerates deal velocity.
What You Can Build
Ship these features with Truto + Workday
Concrete product features your team can ship faster by leveraging Truto’s Workday integration instead of building from scratch.
Real-time employee directory sync
Automatically import and maintain an up-to-date roster of active employees, their job profiles, locations, and contact information from Workday into your product.
Manager hierarchy and reporting-line mapping
Pull Supervisory Organization data from Workday to build accurate org charts and manager-based approval workflows inside your application.
Hire and termination event detection
Detect new hires, terminations, and leaves of absence as they happen in Workday to trigger provisioning, deprovisioning, or notification workflows in your product.
Pre-hire record creation from external systems
Push candidate data from your recruiting or onboarding platform into Workday to initiate the Hire business process without requiring HR to re-enter information.
Cost center and location import for financial routing
Sync Workday cost centers and office locations into your expense, procurement, or IT asset platform to automate budget tagging and geographic routing rules.
Custom field mapping for tenant-specific data
Surface Workday's tenant-specific custom fields — like employee badges, internal skill codes, or union affiliations — and map them into your product's data model without hard-coding per customer.
How It Works
From zero to integrated
Go live with Workday in under an hour. No boilerplate, no maintenance burden.
Link your customer’s Workday account
Use Truto’s frontend SDK to connect your customer’s Workday account. We handle all OAuth and API key flows — you don’t need to create the OAuth app.
We handle authentication
Don’t spend time refreshing access tokens or figuring out secure storage. We handle it and inject credentials into every API request.
Call our API, we call Workday
Truto’s Proxy API is a 1-to-1 mapping of the Workday API. You call us, we call Workday, and pass the response back in the same cycle.
Unified response format
Every response follows a single format across all integrations. We translate Workday’s pagination into unified cursor-based pagination. Data is always in the result attribute.
FAQs
Common questions about Workday on Truto
Authentication, rate limits, data freshness, and everything else you need to know before you integrate.
How does authentication work with Workday?
Workday supports multiple auth models including username/password for its SOAP-based Web Services (WWS), OAuth 2.0 for its REST API, and certificate-based authentication for server-to-server integrations. Most enterprise tenants also require configuring Integration System Users (ISUs) with specific security groups (ISSGs) that control which data the integration can access. Truto handles this complexity so your team doesn't have to build and maintain the auth flow.
Does Workday expose a REST API or only SOAP?
Workday offers both. However, the SOAP-based Workday Web Services (WWS) is far more comprehensive and is what most enterprise integrations rely on — it exposes business processes, custom fields, and deep organizational data that the REST API does not fully cover. Truto can abstract the underlying protocol so you interact with a clean API regardless of whether SOAP or REST is used underneath.
Can I access custom fields that are unique to each customer's Workday tenant?
Yes, but this is one of the hardest parts of a Workday integration. Every Workday tenant is heavily customized — no two instances look alike. Custom fields, calculated fields, and custom objects vary per customer. Truto can help map these tenant-specific fields dynamically so you don't need to hard-code per deployment.
Is this integration available today on Truto?
The Workday integration is built on request. There are no pre-built Unified API resources or tools available yet, but Truto can scope and build the integration based on your specific data requirements and use cases. Reach out to discuss your needs.
Can I do delta syncs or do I have to pull all employee data every time?
Workday's Get_Workers operation supports an 'As_Of_Effective_Date' and 'Updated_From' parameter that lets you pull only records changed since your last sync. This delta sync approach is critical for performance in tenants with tens of thousands of employees and helps stay within rate limits.
What are Workday's rate limits and how do they affect large syncs?
Workday enforces rate limits that vary by tenant configuration and API type. SOAP API calls are generally throttled per-session, and large Get_Workers responses must be paginated. Workday admins can also set concurrency limits on Integration System Users. Truto manages pagination and retry logic to handle these constraints transparently.
