Connect WooCommerce and Exact Online with your AI chat

Partner apps in the Exact App Store book WooCommerce orders with VAT codes for OSS. Your chat builds the steps after the sale: credit invoices for returns, payouts with fees, and margin.

WooCommerce Open Exact Online Open

WooCommerce returns and payouts, booked in Exact Online.

  • When a refund is made in WooCommerce, create the credit invoice in Exact Online and link it to the original invoice.
  • When a payout from your payment provider arrives, split it into orders, refunds and fees and book the fees on the right ledger in Exact Online.
  • Each week, send the margin per product from the cost price in Exact Online and the WooCommerce sales.

WooCommerce and Exact Online stay the core: your chat writes an adapter for each API, and Hypamoon runs the flows in your project. Reading starts after you click Allow in the portal, and every change in either system waits for your approval. How adapters work

The standard integration

What already exists between WooCommerce and Exact Online, from the vendors' own pages.

Status
Through an app. A partner app or a shipping platform connects the two.
What it does
The Exact App Store lists partner apps such as Webwinkelfacturen, iWebDevelopment and Minty Media. Webwinkelfacturen books customers, items, revenue, VAT, discounts and payment methods, with VAT codes for OSS, ICP and outside the EU.
What you add
Refunds and credit invoices are not mentioned on the Webwinkelfacturen listing, nor are payout fees or cost price.

What each side needs

From our checks of both APIs. Each name links to its full page with sources.

What you need
A consumer key and secret from WooCommerce, Settings, Advanced, REST API. WooCommerce webhooks tell your app about refunds.

Webhooks

Exact Online

What you need
An app you register in the App Center of your own Exact Online environment. Exact uses OAuth with short lived tokens, and the API host depends on your country.
