Hi @HanLiong.Ng,
WC-1 application reports 5 World-Check categories: Sanctions (S),Regulatory Enforcement (RE), Law Enforcement (LE), Politically Exposed Persons (PEP), and OtherBodies (OB) you can view at the Case Management, Case, and Profile levels. At the Profile (Key Data) level you can view the Sub-Categories. So a PEP name may have a PEP N Sub-Category (National Governments). The categories and sub-categories are in the API Request Return for each profile.
There is no published API command to return all the category and sub-categories for World-Check One, however there is a document out on the TR-Hub... I'll email you the link.
I hope this helps,
Brian
