Let's get started

Start here

In order to make authorized requests towards the API's, you need to be registered as a partner. Just go to our registration site and sign up! You will be provided with all necessary credentials via the email you provide upon registration, and access to a Bookkeeping & Invoicing/eAccounting and Payroll company in our sandbox environment.

For more detailed information regarding authentication and authorization, take a look at the Authentication guide.

Pro tip: Have a look around in the company, create an invoice, or a supplier, to get a better understanding of what it looks like for your customer, before you get into the integration.

Note: Sandbox companies are for app development only. To get access to the production environment, contact API support.

Endpoints

Each API entity has its own endpoint. Check out which these are here.
All endpoints are documented with descriptions, including which properties are required and which are optional. Required fields are marked in bold to make them easy to identify.

Status page, error codes, and pagination?

Everything you might need is documented, and you can find everything in the table of contents to the left, or in the menu up top. If there's anything missing, let us know: API support.

And hey, don't miss out on our changelog where we post updates on new endpoints, properties, and changes regarding our API.

Support

If you have a more complex question or a customer specific question, we prefer that you communicate with us via email.

Don't forget the Error ID

If you encounter an error of any kind, we always return a unique Error ID on all non-successful requests.
Provide that Error ID to the API support to decrease response time.
