Junction auto update

Request Access
Service version: v1
Last edit: 2023.10.12

Purpose

Junction Auto-Update is a REST API endpoint designed for the streamlined and efficient update of junctions. It simplifies the junction update process by requiring minimal input parameters.

Before committing to the update of a junction, users have the option to check the Junction definition preview. This feature allows users to review and verify the generated junction based on the provided area.

The response contains the junction ID that you can use to fetch junction data via Junction definition details

Request data

You can update the junction in an automatic way by sending a PUT request, as shown in the following example.

  • Constants and parameters enclosed in curly brackets must be replaced with their values.
  • Please see the following Request parameters section with the required and optional parameter tables for their values. The generic request format is as follows.

HTTPS method: PUT
