Add/Remove Business Process IT System Entities by Internal ID

Overview Endpoint Reference Responses

Overview

The PUT /api/hub/external-integration/business-processes/internal-id/{internalId}/it-system-entities endpoint assigns a complete list of IT Systems to a Business Process, identified by the Business Process's Internal ID. This is a full replacement — IT Systems not included in the request body are removed, and any missing ones are added.

⚠ Important: This operation replaces the entire IT System assignment for the Business Process. Any IT Systems currently assigned but not included in the request body will be removed.

What you can do

✓Assign a full set of IT Systems to a Business Process in a single call, replacing any prior assignments

✓Receive the resulting data flow entity structure including IT System nodes, data subject nodes, data elements, processing purposes, and transfer relationships

Prerequisites

✓A valid OAuth 2.0 bearer token

✓An existing Business Process Internal ID (internalId)
