How do I integrate Alegra API with my application?

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

What Alegra data can I access through Apideck?

Our Alegra integration supports 16+ data models including contacts customers, contacts suppliers, taxes, and categories. You can perform read and write operations through our unified API, working with the same code structure across all accounting platforms.

How does Alegra authentication work with Apideck?

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

Does Apideck support Alegra webhooks?

Yes, Apideck provides Alegra's native webhook events. Our unified webhook system normalizes events across all integrations, so you handle Alegra events with the same code you use for other accounting platforms.

Why use Apideck instead of Alegra's direct API?

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

How quickly can I build a Alegra integration?

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