## FAQs

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

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

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

Our Wave integration supports 11+ data models including customers, vendors, invoices, and accounts. You can perform read and write operations through our unified API, working with the same code structure across all accounting platforms.

### How does Wave authentication work with Apideck?

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

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

While Wave 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 Wave.

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

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

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

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