# Connect via Webhook

{% hint style="info" %}
**Good to know:** All mempool data are sent as a JSON payload, please note that we also support Slack & Discord webhook URLs.

Slack webhooks must start with <https://hooks.slack.com/services>\
Discord webhooks must start with <https://discordapp.com/api/webhooks>

{% endhint %}

## Getting Started

### Setup API Configuration

1. Create a Mempool Node account, by clicking the "Register" button on the top right of our [Dashboard](https://dashboard.mempoolnode.com/?ref=apiDocs), and complete the registration form. &#x20;
2. Mempool Node will create an API Key named "Mempool Key 1" for your account, that you can configure to use. You can create additional API keys from your [Dashboard](https://dashboard.mempoolnode.com/?ref=apiDocs) by clicking the "+" button at the top right of Mempool Key 1.

### Configure Webhook

Configure a new webhook for your API configuration by clicking "⋮" next to the On/Off toggle on the right, and selecting "Configure". This will open a form, in which you populate your webhook specifics: Webhook URL, Blockchain(Currently Ethereum & Binance Smart Chain are supported) & Watched Addresses. Once completed, click the green "Save" button.

### Add Address to Watch

By default there is a field available for you to enter an address to watch, however, to add an additional address to watch click the "+" on the right of "Watched Addresses" and enter the address you wish to watch. Once completed, click the green "Save" button.

{% hint style="info" %}
Ethereum & Binance Smart Chain addresses start with "0x" followed by 40 characters. Any valid ETH or BSC address will be accepted, this also includes external accounts and smart contract addresses.
{% endhint %}

To stop watching a specific address entered, you can click the trash/bin icon next to the address, and once saved, you'll no longer watch that address. Once completed, click the green "Save" button.

### Start Receiving Webhooks

Now that everything is configured, all you have to do is toggle the On/Off switch for the specific Mempool API Key you wish to start receiving data, and your mempool data will begin to fly in. Viola!
