What is a Merchant Blocklist?
A merchant blocklist is a deny-list of vendors an agent may never pay — the explicit complement to the allowlist's default-deny.
How it works
You list banned merchants (known-scam vendors, banned categories of vendors).
Any transaction to a blocked merchant returns BLOCKED immediately.
It's the counterpart to the merchant allowlist's default-deny.
Allowlist vs blocklist
Allowlist: only approved vendors pass — everything else is blocked.
Blocklist: everything passes unless explicitly banned.
Most teams run the allowlist as primary and add blocklist entries for clarity.
FAQ
Do I need both?
The allowlist is the stronger default. The blocklist is useful when you want to permit most vendors but hard-ban a few.
Can I update it live?
Yes — rules are managed via the dashboard and API.
