Configuration — Sanctions sources PUQ Sanctions Checker module WHMCS Order now | Download | Community Addons → Sanctions Checker → Configuration → Sanctions sources. All settings are saved with the green Save Changes button; only the license key lives in Setup → Addon Modules. Local lists (OpenSanctions mirrors) Official government sanctions lists mirrored by the OpenSanctions project as clean machine-readable files (~2 MB each). No registration or API key required. The files are imported into your database and matching runs locally — no client data leaves your server. Synchronized daily by cron. Matching engine Setting Default Description Full name match threshold 85% Similarity of the whole name required to report a match. Enable trigram matching + threshold on / 65% 3-letter-chunk comparison, catches typos and letter swaps. Trigram minimum name length 6 Trigrams run only when both names have at least this many letters — short names would match randomly. Enable per-word matching + minimum words on / 1 Only the surname or a company word can trigger a match; a first-name-only hit never flags. Minimum 1 flags surname-only matches (with a lower score); 2 requires first + last name. Word similarity threshold 85% How similar two words must be to count as a pair (catches Ivanov / Ivanoff). The methods are explained in detail in How the matching engine works. US Consolidated Screening List API Real-time fuzzy search against 11 US lists (OFAC SDN, BIS Entity List, State Department). Get a free API key at the ITA API portal; results below CSL minimum match score (default 90) are ignored. Client names are sent to trade.gov over HTTPS. Blocked countries Comma-separated ISO-2 country codes (e.g. RU,BY,IR,KP,SY,CU). The country from the client profile is compared against this list; a match is reported with score 100.
