AI-generatedSummary
Modify an existing Toss Invest order by submitting its order ID and updated order type, with optional quantity and limit price, to the order modification endpoint. The request uses the selected or credential-default account sequence and returns the API response.
Inputs
- Account Sequence — Optional account sequence from Account > Get Many. Leave empty to use the credential default; one must be available.
- Order ID (required) — ID of the order to modify.
- Order Type — Limit or Market. Defaults to Limit.
- Quantity — Quantity to set. The UI notes that it is required for Korean modifications and should be omitted for US modifications.
- Price — Limit price; required for limit orders and must match the market tick size.
- Confirm High Value Order — Whether to confirm orders worth KRW 100,000,000 or more. Defaults to false.
Output shape
A single item containing the Toss Invest API response for each input item.
The request sends orderType and confirmHighValueOrder, and includes quantity and price only when non-empty. Authentication or API errors stop execution unless Continue On Fail is enabled, in which case an item with an error field is returned.
