Polymarket Geoblock API Integration for Trading Applications

A practical guide to enforcing Polymarket geographic restrictions in bots, dashboards and customer-facing trading applications.

Check before enabling execution

Run the official geoblock check from the user’s actual request path before showing or enabling order actions. Do not infer eligibility from language, wallet address or account history.

Represent restricted modes explicitly

Some locations can be fully blocked while others may be close-only. Model allowed, close-only and blocked states so the interface never turns a restricted response into a generic API error.

Do not build bypass behavior

VPN detection evasion and location spoofing create legal and account risk. Log the decision timestamp and country or region result while minimizing stored personal data.

Fail safely during uncertainty

If the compliance endpoint is unavailable, disable new risk rather than assuming permission. Existing positions may require a separately authorized close-only workflow.
