How do I integrate Workday API with my application?

Apideck provides a unified Accounting API that makes Workday integration simple. Sign up for free, enable Workday in your dashboard, and use our Vault component to let your users connect their Workday accounts. We handle OAuth authentication, token refresh, and data normalization automatically.

What Workday data can I access through Apideck?

Our Workday integration supports 23+ data models including workers, companies, departments, and customer invoice. You can perform read and write operations through our unified API, working with the same code structure across all accounting platforms.

How does Workday authentication work with Apideck?

Apideck's Vault handles Workday authentication completely. Your users connect their Workday accounts through our secure, white-label UI. We manage OAuth tokens, automatic refresh, and credential storage, so you never have to implement Workday's auth flow yourself.

Does Apideck support Workday webhooks?

Yes, Apideck provides real-time notifications when Workday data changes. Our unified webhook system normalizes events across all integrations, so you handle Workday events with the same code you use for other accounting platforms.

Why use Apideck instead of Workday's direct API?

Using Apideck's unified API instead of Workday's direct API saves significant development time. You get normalized data models, automatic auth handling, and the same integration code works with 200+ other apps. When Workday updates their API, we handle the changes so your integration keeps working.

How quickly can I build a Workday integration?

Most developers ship a working Workday integration within a day using Apideck. Sign up for a free trial (no credit card required), enable Workday, and make your first API call within minutes. Our SDKs for Node.js, Python, and other languages make implementation straightforward.
