Build on top of Online Erhverv
A platform for tradespeople that plays well with your systems. Connect accounting and calendar with no code, automate via Zapier and Make, push leads in with webhooks — or grab our REST API and build a proper integration.
Native integrations, Zapier/Make and webhooks are live today. The REST API is in partner beta — you get a key on request.

Pick the level that suits you. Most people start no-code and build up from there.
Push data in, in real time
Got a website, a CRM or a chatbot that captures customers? Send them straight into the tradesperson’s account the second they land. Every call carries an HMAC signature, so the receiver can trust it came from you.

Illustrative example. You get the exact reference and your test environment together with your key.
Built to handle real customer data
You work with the tradesperson’s customers, invoices and addresses. It has to be watertight — in the integration layer too.
Every API key is tied to one company. You only see data for the account the key belongs to.
Every webhook call has an HMAC signature in the header, so you can verify it actually came from us.
All traffic runs over TLS, and repeated calls are rejected with idempotency keys, so nothing happens twice.
The database is hosted in the EU (Ireland), separated per company with Row-Level Security. Your data is never sold on.

Three steps to a key
No lengthy application. Tell us what you want to build, and we’ll quickly work out the right level.
An email with what you want to send in or pull out, and for whom. We usually reply the same day.
You get an API key, the full reference and a test environment, so you can build without touching real data.
Once it works in test, you switch to the production key. We keep an eye on it running.
Questions about the API
If your answer isn’t here, write in — we’re developers ourselves and answer concretely.
Is the API publicly available?
Native integrations, Zapier/Make and inbound webhooks are live for all customers today. The full REST API — where you can read and write customers, quotes and invoices — is in a controlled partner beta. Write to us and you’ll get a key and the full reference.
What does it cost to use the API?
Integrations and webhooks are included in your plan at no extra charge. We agree REST API access individually with partners and wholesalers — typically at no extra cost if it brings value to both sides.
What format do you use?
Plain REST: JSON payloads over HTTPS, a Bearer token in the Authorization header, and webhooks with an HMAC signature you can verify. Nothing exotic — just what you expect.
Can I test against a test environment?
Yes. When you get a key, you also get access to a test environment, so you can build and debug without touching real customers, invoices or text messages.
Who typically builds on top of you?
Wholesalers and builders’ merchants, accounting and payroll partners, vertical solutions and agencies that want to send leads in or pull data out for a tradesperson client. If you’re unsure whether your case fits, give us a call — we answer honestly.
Got something that needs to talk to us?
