Welcome to the API reference for API.1. Here you will find all the information you need to be able to consume API.1 endpoints and start inviting your customers to connect their ERP systems.

Authentication

You must get an API Key by logging into the Client Portal. This is the key that is needed to call all of the API endpoints in API.1.

APIs

We currently offer two APIs for you to consume:

Client API

Use this to create Consent, and then use the created Consent ID to invite your Customer to onboard through the Onboarding UI.

Accounting API

Use this to access data from your customers' ERP System with the Consent ID, once your Customer has onboarded and created a Connection to their ERP System.
