How do I integrate FreshBooks API with my application?

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

What FreshBooks data can I access through Apideck?

Our FreshBooks integration supports 13+ data models including clients, ledger accounts, bill vendors, and taxes. You can perform read and write operations through our unified API, working with the same code structure across all accounting platforms.

How does FreshBooks authentication work with Apideck?

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

How do I keep my app in sync with FreshBooks?

While FreshBooks 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 FreshBooks.

Why use Apideck instead of FreshBooks's direct API?

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