1. **For Individual Markets:** Always use the slug method for best performance
2. **For Category Browsing:** Use tag filtering to reduce API calls
3. **For Complete Market Discovery:** Use the events endpoint with pagination
4. **Always Include `closed=false`:** Unless you specifically need historical data
5. **Implement Rate Limiting:** Respect API limits for production applications

Contents:

  • Request Payload Parameters
  • Order types
  • Response Format

  • Insert Statuses

This endpoint requires a L2 Header

Create and place an order using the Polymarket CLOB API clients. All orders are represented as "limit" orders, but "market" orders are also supported. To place a market order, simply ensure your price is marketable against current resting limit orders, which are executed on input at the best price.

POST /<clob-endpoint>/order

Request Payload Parameters

Name Required Type Description
order yes Order signed object
owner yes string api key of order owner
orderType yes string order type ("FOK", "GTC", "GTD")

An order object is the form:

Name Required Type Description
salt yes integer random salt used to create unique order
maker yes string maker address (funder)
signer yes string signing address
taker yes string taker address (operator)
tokenId yes string ERC1155 token ID of conditional token being traded
makerAmount yes string maximum amount maker is willing to spend
takerAmount yes string minimum amount taker will pay the maker in return
expiration yes string unix expiration timestamp
nonce yes string maker's exchange nonce of the order is associated
feeRateBps yes string fee rate basis points as required by the operator
side yes string buy or sell enum index
signatureType yes integer signature type enum index
signature yes string hex encoded signature
  • FOK: A Fill-Or-Kill order is an market order to buy (in dollars) or sell (in shares) shares that must be executed immediately in its entirety; otherwise, the entire order will be cancelled.
  • FAK: A Fill-And-Kill order is a market order to buy (in dollars) or sell (in shares) that will be executed immediately for as many shares as are available; any portion not filled at once is cancelled.
  • GTC: A Good-Til-Cancelled order is a limit order that is active until it is fulfilled or cancelled.
  • GTD: A Good-Til-Date order is a type of order that is active until its specified date (UTC seconds timestamp), unless it has already been fulfilled or cancelled. There is a security threshold of one minute. If the order needs to expire in 90 seconds the correct expiration value is: now + 1 minute + 30 seconds
Name Type Description
success boolean boolean indicating if server-side err (success = false) -> server-side error
errorMsg string error message in case of unsuccessful placement (in case success = false, e.g. client-side error, the reason is in errorMsg)
orderId string id of order
orderHashes string[] hash of settlement transaction order was marketable and triggered a match

Insert Error Messages

If the errorMsg field of the response object from placement is not an empty string, the order was not able to be immediately placed. This might be because of a delay or because of a failure. If the success is not true, then there was an issue placing the order. The following errorMessages are possible:

Error Success Message Description
INVALID_ORDER_MIN_TICK_SIZE yes order is invalid. Price breaks minimum tick size rules order price isn't accurate to correct tick sizing
INVALID_ORDER_MIN_SIZE yes order is invalid. Size lower than the minimum order size must meet min size threshold requirement
INVALID_ORDER_DUPLICATED yes order is invalid. Duplicated. Same order has already been placed, can't be placed again
INVALID_ORDER_NOT_ENOUGH_BALANCE yes not enough balance / allowance funder address doesn't have sufficient balance or allowance for order
INVALID_ORDER_EXPIRATION yes invalid expiration expiration field expresses a time before now
INVALID_ORDER_ERROR yes could not insert order system error while inserting order
EXECUTION_ERROR yes could not run the execution system error while attempting to execute trade
ORDER_DELAYED no order match delayed due to market conditions order placement delayed
DELAYING_ORDER_ERROR yes error delaying the order system error while delaying order
FOK_ORDER_NOT_FILLED_ERROR yes order couldn't be fully filled, FOK orders are fully filled/killed FOK order not fully filled so can't be placed
MARKET_NOT_READY no the market is not yet ready to process new orders system not accepting orders for market yet

When placing an order, a status field is included. The status field provides additional information regarding the order's state as a result of the placement. Possible values include:

Status Description
matched order placed and matched with an existing resting order
live order placed and resting on the book
delayed order marketable, but subject to matching delay
unmatched order marketable, but failure delaying, placement successful
