Cancel up to 100 CLOB orders in a single request. Order IDs may belong to different markets and events. CLOB-only: any AMM order is rejected per-item with UNSUPPORTED_ENGINE. Ownership is enforced upstream — order IDs the caller does not own return ORDER_NOT_FOUND. See the Batch orders concept page for limits, semantics, and rate-limit behavior.

​
Authentication

Write authentication required — X-Public-Key, X-Timestamp, and X-Signature headers. See the Authentication guide.

​
Headers

​
Idempotency-Key
string
Optional. 1–255 characters of [A-Za-z0-9_-]. Retries within 24 hours that share the same key, body, and route replay the original response with Idempotent-Replayed: true. A retry with the same key but a different body is rejected with 422. A concurrent retry (sent while the first is still in flight) is rejected with 409 — back off briefly and retry once the first call has finished. Transient responses (5xx, 429, 408) are not cached, so you can recover by retrying.

​
Request body

​
orderIds
array
required
1–100 order UUIDs to cancel. Each ID is processed independently — failures on one ID do not abort the rest of the batch.

​
Example request

PUBLIC_KEY="pk_live_abcdef123456"
SECRET_KEY="sk_live_secret789xyz"
TIMESTAMP=$(date +%s)
METHOD="DELETE"
URL_PATH="/v1/pm/orders/batch"
BODY='{"orderIds":["f6a7b8c9-d0e1-2345-fabc-678901234567","a1b2c3d4-e5f6-7890-abcd-ef1234567890"]}'

BODY_HASH=$(printf '%s' "$BODY" | openssl dgst -sha256 -hex 2>/dev/null | sed 's/.*= //')
PAYLOAD="${TIMESTAMP}.${METHOD}.${URL_PATH}.${BODY_HASH}"
SIGNATURE=$(printf '%s' "$PAYLOAD" | openssl dgst -sha256 -hmac "$SECRET_KEY" -binary | base64)

curl -X DELETE "https://relay.bayse.markets${URL_PATH}" \
  -H "X-Public-Key: ${PUBLIC_KEY}" \
  -H "X-Timestamp: ${TIMESTAMP}" \
  -H "X-Signature: ${SIGNATURE}" \
  -H "Idempotency-Key: 9d3f2c0e-7b1a-4e5d-9f80-3a8b1c2d4e5f" \
  -H "Content-Type: application/json" \
  -d "$BODY"
This DELETE carries a JSON body, so the signing payload’s bodyHash is the SHA-256 hash of the body — not the empty hash used for body-less DELETEs like Cancel order.

​
Response

​
engine
string
Always CLOB for batch endpoints today.
​
results
array
Per-order outcomes, in the same order as the request.

Only CLOB orders with status open or partial_filled can be cancelled. AMM orders execute instantly and cannot be cancelled — sell your shares to exit instead. Batch cancel charges one rate-limit token per ID.
