How do I integrate Group S API with my application?

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

How does Group S authentication work with Apideck?

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

How do I keep my app in sync with Group S?

While Group S has limited native webhook support, Apideck provides polling-based sync and virtual webhooks to keep your data current. Configure your sync frequency in the dashboard, and we'll handle fetching updates from Group S.

Why use Apideck instead of Group S's direct API?

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

How quickly can I build a Group S integration?

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