# Voyages

## **Prerequisites**

No prerequisites.

## **Integration Set-Up**

Accounting systems often require voyage related data before transferring accounting related transactions. Set up a scheduled task and use the request under [#data-transaction](#data-transaction "mention") to gather all voyages that has been modified since the last time a scheduled task was run.

## **Test Data**

Modify some existing voyages in the Booking and Operations module for testing, for example, changing a date in the schedule (***note**: changing dates will also affect the schedule for other voyages*).

## **Data Transaction**

### Get new voyages using webhooks

To get new voyages in [Webhooks](/api-release-8.25/dataloy-rest-api/webhooks.md) the following subscription can be created:
