Retrieve all payment-screening risks attached to a single transaction. The transaction is addressed by exactly one of two mutually exclusive query parameters: transaction_identifier (the internal ComplyAdvantage payment identifier, a UUID) or transaction_external_identifier (the client's own external payment reference, an arbitrary string). Supplying both, or neither, is a 400. Returns a 200 with an empty risks array when the transaction exists but produced no risks. Results are ordered by created_at ascending; ties are broken by risk identifier.

You need "Access to base payment screening functionality" enabled to use this endpoint.
