How do I integrate Yuki API with my application?

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

What Yuki data can I access through Apideck?

Our Yuki integration supports 10+ data models including gl accounts, transactions, projects, and contacts customers. You can perform read and write operations through our unified API, working with the same code structure across all accounting platforms.

How does Yuki authentication work with Apideck?

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

How do I keep my app in sync with Yuki?

While Yuki 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 Yuki.

Why use Apideck instead of Yuki's direct API?

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

How quickly can I build a Yuki integration?

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