Publish events with the activity ID
As we have mentioned above, the event needs to have mandatory ‘activityId’ field in the correlation data of the event and the field needs to be as JSON string to use it as FACET type. Therefore convert your activityId as JSON string and publish to WSO2 DAS. For example, sample JSON formed activity shown below.
