How do I integrate Kustomer API with my application?

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

How does Kustomer authentication work with Apideck?

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

How do I keep my app in sync with Kustomer?

While Kustomer 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 Kustomer.

Why use Apideck instead of Kustomer's direct API?

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

How quickly can I build a Kustomer integration?

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