Unable to place order

Developer API

Here I tried to buy an instrument in derivatives but its return error without any explanation.
Here is my sample code:

                    $headers = array(
				'Content-Type: application/json',
				'x-jwt-token: ' . $this->jwt_token
			);

			$ch = curl_init();
			curl_setopt($ch, CURLOPT_URL, "https://api.upstox.com/v2/order/place");
			curl_setopt($ch, CURLOPT_POST, true);
			curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
			curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
			curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
			$response = curl_exec($ch);
			curl_close($ch);

Its returns:
{"status":"error","errors":[]}

Value of $data in request as below:
{"txn_type":"BUY","tag":"string","product":"D","instrument_token":"NSE_FO|60331","quantity":"50","validity":"DAY","order_type":"MARKET","price":"0","trigger_price":"","is_amo":false}

Please take note of the following:

  • Our authentication method utilizes bearer tokens rather than JWT tokens.

  • When specifying transaction details in the data, use transaction_type instead of txn_type to indicate whether it is a buy or sell order.

Here is a working example for your reference.

<?php

$headers = [
    'Content-Type: application/json',
    'Authorization: Bearer {your_access_token}',
];

$data = [
    'quantity' => 50,
    'product' => 'D',
    'validity' => 'DAY',
    'price' => 0,
    'tag' => 'string',
    'instrument_token' => 'NSE_FO|60331',
    'order_type' => 'MARKET',
    'transaction_type' => 'BUY',
    'disclosed_quantity' => 0,
    'trigger_price' => 0,
    'is_amo' => true,
];

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://api.upstox.com/v2/order/place");
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$response = curl_exec($ch);
curl_close($ch);

?>

I hope the above information is helpful.

Now I’m getting this error that trigger price required where I’m placing a market order. How I set Trigger price for market order?

Set the Trigger price as 0 for market buy order
