Domain Allow/Block Lists

Control which domains can send bid requests to a publisher.

Via Broker

1. Go to Supply → click a publisher → Domains tab
2. Allowlist: type a domain, click Add. Only these domains will be accepted.
3. Blocklist: type a domain, click Block. These domains will be rejected.
4. Click × to remove a domain from either list.

Changes save immediately and take effect within 60 seconds.

“Block spam-site.com on Publisher A”

“Set domain allowlist for publisher X to example.com, trusted.com”

Rules

• Allowlist empty = all domains accepted (default)
• Allowlist set = only listed domains accepted, everything else rejected
• Blocklist = always rejected, even if on allowlist
• Domains are matched exactly (no wildcards)
