# Test request signing

`POST /v0/signingtest`

> **Authentication:** every request must send `X-ConfidentLims-APIKey`, `X-ConfidentLims-Timestamp` (unix seconds) and `X-ConfidentLims-Signature`, an HMAC-SHA256 signature of the request. The examples below call `sign_request()` from the [Request Signing guide](https://api.confidentcannabis.com/v0/docs/request-signing.md) — read it first. Request bodies are form-encoded (`application/x-www-form-urlencoded`), never JSON.

Debug endpoint for verifying your request signing implementation. Use any valid credentials and send any fields you like: field values are folded into the signature but are otherwise ignored.

A correctly signed request succeeds and returns nothing but the success flag; an incorrectly signed one is rejected like any other request.

Values worth signing while testing, because they exercise character escaping: `hello`, `hello, world!` and `foobar!'()*+~"`.

## Body parameters (application/x-www-form-urlencoded)

- `example_field` (string, optional) — Any string. Included in the signature, otherwise ignored.
  Example: `hello, world!`

## Responses

### 200 Success

No fields beyond the success envelope.

Example:

```json
{
  "success": true
}
```

### 400 Bad request

The request was malformed or failed validation. Validation failures include per-field messages in `error_details`. Possible `error_code` values: `invalid_request`, `request_too_old`.

### 401 Unauthorized

Authentication failed. Possible `error_code` values: `missing_api_key`, `invalid_api_key`, `invalid_credentials_type`, `api_access_restricted`, `api_access_denied`, `missing_signature`, `missing_timestamp`, `invalid_timestamp`, `invalid_signature`.

### 403 Permission denied

The API key is valid but does not have permission for this endpoint (for example, a client key calling a labs endpoint). Possible `error_code` values: `permission_denied`.

## Examples

### cURL

```bash
# X-ConfidentLims-Signature: see the Request Signing guide - https://api.confidentcannabis.com/v0/docs/request-signing.md
curl -X POST 'https://api.confidentcannabis.com/v0/signingtest' \
  -H 'X-ConfidentLims-APIKey: YOUR_API_KEY' \
  -H 'X-ConfidentLims-Timestamp: UNIX_TIMESTAMP' \
  -H 'X-ConfidentLims-Signature: REQUEST_SIGNATURE'
```

### Python

```python
import time
import requests

# sign_request() is defined in the Request Signing guide:
# https://api.confidentcannabis.com/v0/docs/request-signing.md
from sign_request import sign_request

API_KEY = 'YOUR_API_KEY'
API_SECRET = 'YOUR_API_SECRET'
path = '/v0/signingtest'

data = {
    # optional form fields go here - they are signed too
}

headers = {'X-ConfidentLims-Timestamp': str(int(time.time()))}
headers['X-ConfidentLims-Signature'] = sign_request(
    'POST', path, headers, data, API_KEY, API_SECRET)
headers['X-ConfidentLims-APIKey'] = API_KEY

response = requests.post(
    'https://api.confidentcannabis.com' + path,
    headers=headers,
    data=data,
)
print(response.json())
```

### JavaScript

```javascript
// signRequest() is defined in the Request Signing guide:
// https://api.confidentcannabis.com/v0/docs/request-signing.md
import { signRequest } from './sign_request.js';

const API_KEY = 'YOUR_API_KEY';
const API_SECRET = 'YOUR_API_SECRET';
const path = "/v0/signingtest";

const data = {
  // optional form fields go here - they are signed too
};

const headers = { 'X-ConfidentLims-Timestamp': String(Math.floor(Date.now() / 1000)) };
headers['X-ConfidentLims-Signature'] = signRequest(
  "POST", path, headers, data, API_KEY, API_SECRET);
headers['X-ConfidentLims-APIKey'] = API_KEY;

const response = await fetch("https://api.confidentcannabis.com" + path, {
  method: "POST",
  headers,
  body: new URLSearchParams(data),
});
console.log(await response.json());
