order_complete

Fires when a multi-fill order finishes. One aggregated event per order instead of N individual fills.

polynode exclusive — no other Polymarket data provider aggregates partial fills into order-level events.

Filters

Filter	Type	Description
wallet_addresses	string[]	Wallets to watch (maker or taker on any fill). Max 500.
min_total_usd	number	Minimum total order size in USD.

How It Works

When an order is filled across multiple transactions, polynode buffers the individual fills. After 30 seconds with no new fills for that order_hash, the buffered fills are aggregated and delivered as a single event.
