# Ping

> Check that the Checkout API is reachable and your key is accepted

A health check. Useful for confirming connectivity, DNS and TLS during setup, and for a
liveness probe in your own monitoring.

## Endpoint

```
GET https://api-v4.reeple.ai/charge/ping
```

Authenticate with your **public key**. See [Authentication](/api-reference/authentication).

## Request example

```bash theme={null}
curl https://api-v4.reeple.ai/charge/ping \
  -H "api-key: YOUR_PUBLIC_KEY"
```

## Response

```json theme={null}
{
  "status": "success",
  "statusCode": "00",
  "message": "Welcome to Checkout Service Endpoint"
}
```

<Tip>
  This is the fastest way to tell a credential problem from a connectivity problem. If ping
  succeeds but your order calls fail, the issue is your payload or
  [encryption](/encryption) — not your key or your network.
</Tip>

<Note>
  Ping doesn't touch order data or the payment processor, so a successful response doesn't
  guarantee payments are processing normally. It confirms the API is reachable, nothing more.
