# Create order

To place an order, grab the nonce and msg hash from the nonce api <mark style="background-color:purple;">orders/nonce/</mark> and provide them to the create order api <mark style="background-color:purple;">/orders/create/</mark>.

> Note: You will need to include the JWT Auth token to request headers to access this endpoint. To get the JWT Auth Token, refer the [login](https://docs.brine.fi/tech/api-documentation/account/login) section of this document.

{% hint style="info" %}
If you are affiliated with the Brine organization, please ensure that you add the organization\_key and api\_key to the request body in both the nonce and create endpoints. This field is entirely optional. To obtain these keys, please reach out to Brine at <support@brine.fi>.

Create a new order. (Private 🔒)

Before creating a new order, you’d be required to obtain a nonce by making use of this endpoint. Please note that this is a <mark style="background-color:purple;">Private 🔒</mark> route which means it needs to be authorized by the account initiating this request.

#### Endpoint <a href="#endpoint-1" id="endpoint-1"></a>

```bash
POST /sapi/v1/orders/create/
```

#### Request Headers <a href="#request-headers-1" id="request-headers-1"></a>

```json
{
  "Authorization": "JWT ***"
}
```

#### Request Body <a href="#request-body-1" id="request-body-1"></a>

| Field                  | Type    | Mandatory |
| ---------------------- | ------- | --------- |
| msg\_hash              | STRING  | YES       |
| signature (both r & s) | STRING  | YES       |
| nonce                  | INTEGER | YES       |

> To sign the msg hash obtained after accessing the nonce API, use the [NodeJs SDK signMsgHash](https://github.com/Brine-Finance-Libs/brine-connector-nodejs/blob/5643daec485b13a118413ebeb6893dd8eb3f075b/src/utils.ts#L17) function.

```javascript
import { signMsgHash } from '@brine-fi/brine-connector'

const sign = signMsgHash(createOrderNoncePayload, privateKey); 
```

After successfully generating the signature, you may send it together with additional parameters to create the order, as shown below.

#### Example

```json
{
  "msg_hash": "0x5f128faa6e96360629b1fcb4f24fe9bc547f0d79c7a3aed056d824baa786755",
  "signature": {
    "r": "",
    "s": ""
  },
  "nonce": 931
}
```

#### Response <a href="#response-1" id="response-1"></a>

```json
{
  "status": "success",
  "message": "Created Order Successfully",
