Cancel Batch Orders
Cancel Batch Orders
POSThttps://api.gemini.com/v1/prediction-markets/order/batch/cancel
Cancel 1 to 20 prediction market orders in one authenticated request. The batch is synchronous and non-atomic: invalid IDs reject the entire batch before cancellation begins, while exchange cancellation errors are returned per entry and do not stop later entries.

Batch Behavior
- The complete payload is encoded and signed once.Code
- Each order ID may be a JSON integer or a quoted numeric string.
- Gemini validates every ID before attempting any cancellation. An invalid ID, an empty batch, or more than 20 entries rejects the entire request.
- After validation, cancellations are attempted sequentially and results remain aligned with request order.
- An exchange rejection such as is returned in that entry's result. Other valid cancellations continue to be attempted.Code
