## FAQs

### How do I integrate Fiken API with my application?

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

### What Fiken data can I access through Apideck?

Our Fiken integration supports 19+ data models including companies, customers, vendors, and items. You can perform read and write operations through our unified API, working with the same code structure across all accounting platforms.

### How does Fiken authentication work with Apideck?

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

### How do I keep my app in sync with Fiken?

While Fiken 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 Fiken.

### Why use Apideck instead of Fiken's direct API?

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

### How quickly can I build a Fiken integration?

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