How do I integrate Simployer One API with my application?

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

What Simployer One data can I access through Apideck?

Our Simployer One integration supports 4+ data models including employees, companies, leaves, and departments. You can perform read and write operations through our unified API, working with the same code structure across all hris platforms.

How does Simployer One authentication work with Apideck?

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

Does Apideck support Simployer One webhooks?

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

Why use Apideck instead of Simployer One's direct API?

Using Apideck's unified API instead of Simployer One'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 Simployer One updates their API, we handle the changes so your integration keeps working.
