What is the Java API to retrieve the history of the process activities?

Hello everyone,

I have a question concerning the Camunda Rest API to get the history of the process activites.
The Rest endpoint is the following:

  /history/activity-instance/count

Can someone refer me to the corresponding Java API for this REST resource? Is it a public API?

Thank you.

Hi @mk08,

you can find the interface here:

github.com

camunda/camunda-bpm-platform/blob/master/engine-rest/engine-rest/src/main/java/org/camunda/bpm/engine/rest/history/HistoricActivityInstanceRestService.java#L65-L68


@GET
@Path("/count")
@Produces(MediaType.APPLICATION_JSON)
CountResultDto getHistoricActivityInstancesCount(@Context UriInfo uriInfo);

and the implementation here:

github.com

camunda/camunda-bpm-platform/blob/master/engine-rest/engine-rest/src/main/java/org/camunda/bpm/engine/rest/impl/history/HistoricActivityInstanceRestServiceImpl.java#L86-L89


public CountResultDto getHistoricActivityInstancesCount(UriInfo uriInfo) {
  HistoricActivityInstanceQueryDto queryDto = new HistoricActivityInstanceQueryDto(objectMapper, uriInfo.getQueryParameters());
  return queryHistoricActivityInstancesCount(queryDto);
}

Hope this helps, Ingo
