Thank you for your query.
Via the API, you will find the types as categories. Use the endpoint - /cases/case-system-id/results to fetch the results of a case and search for categories of each match within the results.
"categories": [ "PEP" ],
Hope this helps.
The request and the reponse headers would look something like below -
There would not be a request body as the request type is GET. In the response you would receive the results for the specific case.
