Introduction

Core API vs Extension API

Core API

The Core API allows integrators to retrieve submitted orders as well as to update the Status of existing orders.

• Retrieving tasks from the system

• Updating or enriching task variables

• Supporting workflow-driven integrations

The Core API is typically used by:

• Backend services

• Integration layers

• Automation jobs

• Workflow orchestration components

If your integration needs to modify system state, work with tasks, or enrich workflows, you will primarily use the Core API.

Extension API

The Extension API provides read-only access to publicly consumable data, such as:

• Available municipalities

• Forms per municipality

• Form metadata and URLs

The Extension API is typically used by:

• Public or semi-public frontends

• Portals embedding municipality forms

• Lightweight client applications

If your use case is to discover and display available forms, the Extension API is usually sufficient.
