# Authentication

To use the Message Status API, authenticate with:

- **API KEY** by entering the credentials provided by the Namirial support.


Ensure you include the following headers in your request:

`X-Api-Key: YOUR_API_KEY` (replace YOUR_API_KEY with your actual API key)

Example:


```bash
curl -X GET https://sms-apistatus.test.namirialtsp.com/api/messagestatus/YOUR_MESSAGE_ID \
  -H "Content-Type: application/json" \
  -H "X-Api-Key: YOUR_API_KEY"
```

## Troubleshooting Authentication Issues

Common authentication errors and solutions:

| HTTP Status | Error | Solution |
|  --- | --- | --- |
| `401` | Invalid API key | Verify that you are using the correct API key for the target environment |
| `401` | Expired API key | Contact Namirial support to renew your API key |
| `403` | Forbidden | Your API key does not have permission to access this resource |


For the full list of the environments, see [API References](/products/sms/enterprise-documentation/developer-documentation/apistatus-references).
