# SIGNED Endpoint Example

This step-by-step guide demonstrates how to send a **valid signed payload** from the **Linux command line** using `echo`, `openssl`, and `curl`.

***

## **🔐 Keys**

| Key         | Value                              |
| ----------- | ---------------------------------- |
| `apiKey`    | `vmPUZE6mv9SD5V5e14y7Ju91duEh8A`   |
| `secretKey` | `902ae3cb34ecee2779aa4d3e1d226686` |

***

## **📦 Request Parameters**

| Parameter | Value   |
| --------- | ------- |
| `symbol`  | BTCUSDT |
| `side`    | BUY     |
| `type`    | LIMIT   |
| `volume`  | 1       |
| `price`   | 9300    |

***

## **🧾 Request Body**

```json
jsonCopyEdit{"symbol":"BTCUSDT","price":"9300","volume":"1","side":"BUY","type":"LIMIT"}
```

***

## **🔐 Signature Construction**

Using:

```
sqlCopyEdittimestamp + method + requestPath + body
```

### Example values:

* `timestamp`: `1588591856950`
* `method`: `POST`
* `requestPath`: `/sapi/v1/order/test`
* `body`: `{"symbol":"BTCUSDT","price":"9300","volume":"1","side":"BUY","type":"LIMIT"}`

### **Signature Command (Linux):**

```bash
bashCopyEditecho -n "1588591856950POST/sapi/v1/order/test{\"symbol\":\"BTCUSDT\",\"price\":\"9300\",\"volume\":\"1\",\"side\":\"BUY\",\"type\":\"LIMIT\"}" \
| openssl dgst -sha256 -hmac "902ae3cb34ecee2779aa4d3e1d226686"
```

### **Output:**

```
luaCopyEdit(stdin)= c50d0a74bb9427a9a03933d0eded03af9bf50115dc5b706882a4fcf07a26b761
```

***

## **📡 cURL Command**

```bash
bashCopyEditcurl -X POST https://openapi.coinlocally.com/sapi/v1/order/test \
  -H "Content-Type: application/json" \
  -H "X-CH-APIKEY: vmPUZE6mv9SD5V5e14y7Ju91duEh8A" \
  -H "X-CH-SIGN: c50d0a74bb9427a9a03933d0eded03af9bf50115dc5b706882a4fcf07a26b761" \
  -H "X-CH-TS: 1588591856950" \
  -d '{"symbol":"BTCUSDT","price":"9300","volume":"1","side":"BUY","type":"LIMIT"}'
```
