Do you have a test example that returns a positive watchlist hit?

Yes. This business returns one OFAC hit and works in both production and sandbox:

• Name: 11420 CORP.

• Address: 5599 NW 23rd Ave, Boca Raton, FL 33496

• TIN: 270746046

The hit comes back under the OFAC list with the sanctions program in the details, so you can use it to test how your workflow routes a positive screen.
