Affected Components: Predictions Trading API (CLOB)

Oct 6, 19:56:15 GMT+0
Identified - A scheduled CLOB release requires a brief restart, with downtime of up to \~10 minutes. Order placement, cancels, and fills may be temporarily unavailable. Update to the live-sports order taker delay implementation (orders that return status "delayed"). Before: Held orders were released together at the top of each second. Taker's actual hold was anywhere from 0 to 1s depending on when in the second the order was sent. After: Each held order is released exactly 1s (the market's seconds\_delay) after the engine receive it. Why: Align with standard delay practices thereby making the hold consistent for all takers. This will also allow fills to arrive as a steady stream instead of a burst at the top of each second. Scope: this only applies to the live-sports seconds\_delay hold. The taker delay amount itself is unchanged (orders are still held for seconds\_delay and still return "delayed"), and the crypto taker delay is not affected at all..

Duration: 57 minutes

Affected Components: Predictions Trading API (CLOB)

Jul 27, 19:50:34 GMT+0
Identified - Finalizing the async db release. 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`. Reference PRs: * TypeScript: <https://github.com/Polymarket/clob-client-v2/pull/89> * Python: <https://github.com/Polymarket/py-clob-client-v2/pull/101> * Rust: <https://github.com/Polymarket/rs-clob-client-v2/pull/83>.

Completed - Maintenance has completed successfully. Quick heads up: the txnHash change isn’t live yet. We held off enabling it in prod while we sort out an extra dependency first. No action needed on your end - you’re still getting transactionHashes in the response as usual, and there’s no latency impact from this. We’ll follow up with prod release timing once it’s confirmed.”.
