 #### Tracing Change events and requests Correlation Id
 
+
 To be able to track a change event and the change requests it can become across systems a common id field is present on logs related to each event. The id is generated in `Profile Editor` (NHS UK) which is then assigned to the `correlation-id` header of the request send to our (DoS Integration) endpoint, for a given change event. The `correlation-id` header is then used throughout the handling of the change event in `DoS Integration`.
 
 If a change event does result in change requests being created for `DoS` then the change requests have a `reference` key with the value being the correlation id.
