Integrate Refinitiv World-Check One API for PEP and sanctions screening with risk-based filtering by risk entity category

Steps

1. Authenticate using HMAC-SHA256 signed request headers — compute the signature over the HTTP method, Content-Type, date, and request path
2. POST to /v2/cases/screeningRequest with a CaseSystemId, secondaryFields (dateOfBirth, nationality), and a groupId corresponding to your screening configuration
3. Poll GET /v2/cases/{caseSystemId}/results or handle the webhook callback to retrieve the screened result
4. Filter results by the entityType and primaryName fields; use the category field to separate PEP hits from sanctions hits
5. For each ongoing customer relationship, resubmit a screening request at the interval required by your AML policy (typically monthly or on trigger events)
