Events from the CommunicationParty API

Slim events

Events from the CommunicationParty API are 'slim'. This means that the event itself does not contain the entity data. Instead, it only carries metadata, including properties such as sequenceNumber, herId and eventType.

To retrieve the full entity data, you must make an additional call to: GET communicationparty/{herId}.

Once processed, subsequent events can be retrieved incrementally by calling:

GET /event?fromSequenceNumber=sequenceNumber+1 where sequenceNumber refers to the last successfully processed event.

{
  "sequenceNumber": 123,
  "herId": 1234567,
  "eventType": "CommunicationPartyUpdated",
  "eventTimestamp": "2026-02-24T09:42:44.641+01:00"
}

Types of events

Note

Each communication party has a CommunicationParyCreated event that stems from the initial data population of the API.
