Place Order

API to place an order to the exchange. The instrument_token required for the stock or contracts should be obtained from the BOD instruments.

Upon successfully placing the order with the exchange, a unique order_id is provided in the success response, which can be utilized for order modification or cancellation. If you intend to place an order outside of market hours, the 'is_amo' (After Market Order) should be set to 'true'. You can assign a tag(unique identifier) to your order, allowing you to retrieve orders associated with that tag using the Order History API.

NOTE

If you represent a business aiming to incorporate order flow management (including placing, canceling, and modifying orders), please visit the Uplink Business. The direct HTTP order placement API integration is intended for individual API users.
