# Generate webhook secret

**How It Works**

Each time this endpoint is called, Vesicash generates a new cryptographic secret tied to your account. You use this secret on your server to validate the `mor-signature` header on every incoming webhook request.

1. **Call this endpoint**

   `POST to /v1/account/generate-webhook-secret` with your secret-key. No request body is needed.
2. **Store the secret securely**

   Save the returned `webhook_secret` in your environment variables or secret manager. Never expose it in client-side code or logs.
3. **Verify incoming webhooks**\
   On every Vesicash webhook, compute an HMAC-SHA256 signature of the raw request body using your secret, then compare it against the `mor-signature` header.

**🔴 Regenerating Invalidates the Previous Secret**

Calling this endpoint generates a brand new secret and immediately invalidates the old one. Any webhook verification using the previous secret will fail. Update your environment variables before regenerating in production.
{% endhint %}

#### Headers

| Name       | Type   | Decsription              |
| ---------- | ------ | ------------------------ |
| secret-key | string | Your Vesicash secret key |

#### Response

On a successful request, the API will return a response with the following structure:

* `webhook_secret` (string): The generated webhook secret that will be used for authentication.

```
{
  "status": "",
  "code": 0,
  "message": "",
  "data": {
    "webhook_secret": ""
  }
}

            
```

**NOTE:** **Webhook Authentication Using HMAC-SHA256** After authentication using the specified method, the generated webhook token must be stored in a secure location (for example, a secrets manager or encrypted configuration store). The webhook signature is created by computing an HMAC-SHA256 hash on a single string that must be reconstructed exactly on your server.

```
HMAC-SHA256(   your_webhook_secret,   timestamp + "." + raw_request_body )  
```
