This cuts latency on the core matching engine, but it changes how you get transaction hashes after posting an order. **What to expect:** * Trading intermittent during maintenance, for up to 1.5h. * Brief post-only window after restart (2 min) before normal matching resumes. Cancels accepted. * There may be 503 errors during the maintenance, where trades would not be accepted * There will be brief period of degradation with the get /orders endpoint. Post-only: only orders explicitly set with postOnly: true are accepted. Regular limit orders without the flag, market orders, and any taking liquidity will be rejected. Cancels for existing orders will still go through. [**See POST /order API reference for the post-only flag.**](https://docs.polymarket.com/api-reference/trade/post-a-new-order#body-post-only) **What's changing** **for developers** Today, `POST /order` and `POST /orders` return `transactionHashes` inline on successful FAK/FOK matches. After this rollout, those endpoints won't return `transactionHashes` at all — you'll get `tradeIDs` instead. * tradeIDs behavior itself isn't changing: on a match you get tradeIDs back, on no match or failure you don't. * Websocket updates are unchanged. If you're already reading fills off the websocket, nothing to do here. **What you need to do** On CLOB client (TS / Python / Rust): it handles this for you — resolves transactions after posting and returns hashes, successful trades, and any failures. Just bump to the latest version. Custom API integration: if you depend on `transactionHashes` from the REST response, you'll need to resolve them yourself off `tradeIDs` — poll trades until each has a hash or comes back `FAILED`.
