# Add JWT Authentication to Your undefined API



## How Zuplo Handles It

Let Zuplo issue short-lived JWTs signed with a JWKS your undefined backend can verify — no long-lived API keys touch your origin.

## undefined Backend Code

```yaml
---
title: HAProxy JWT Authentication
framework: HAProxy
language: C
description: Secure your HAProxy API using JWT authentication with JWKS.
---
# HAProxy JWT Authentication

To secure your HAProxy API with JWTs, you'll need to validate the token against
the JWKS issuer.
```

## Example Request

```bash
curl -X GET \
  'https://your-api.zuplo.dev/your-route' \
  -H 'Authorization: Bearer YOUR_API_KEY'
```
