# Webhooks

Webhooks provide simple server-to-server communication. When your customers make payments, your web backend is notified about the payment details, so that you can proceed with your customer's order. With each payment event, we make a https request to your configured webhook url.

### Configuration

#### Webhook URL

To configure a webhook endpoint go to **Dashboard > Settings > Developer Settings** \
Enter your web application endpoint that you want to listen notification messages from Phenixio servers. \
Example: `Default Webhook URL: https://yourwebsite.com/phenixio-event/`

#### Webhook-Access-Key

To prevent malicious requests reaching to the webhook endpoint on your web application, you can configure an Access-Key on your backend. Then enter your Access-Key on **Dashboard > Settings > Developer Settings.** Now our webhook requests to your server will include a `PHENIXIO-WEBHOOK-KEY` header.

Now you can learn more about Payment Event Tokens in the next section.
