## 1. How to Connect via cURL

Use cURL to establish a BNB RPC connection with the following command:

```curl
curl -X POST -H 'Content-Type: application/json' --data '{"method": "METHOD_PARAMS", "params": [RPC_METHOD], "id": 1}' 'YOUR_ENDPOINT_URL?auth=YOUR_AUTH_TOKEN'
```

* Replace `YOUR_ENDPOINT_URL` with the Endpoint URL in the [Blockdaemon app](https://app.blockdaemon.com/).
* Replace `YOUR_AUTH_TOKEN` with the Auth Token in the [Blockdaemon app](https://app.blockdaemon.com/).
* Replace `RPC_METHOD` with your chosen [RPC method](https://docs.blockdaemon.com/docs/allowed-bnb-rpc-methods).
* Replace `METHOD_PARAMS` with parameters from the selected RPC method.

## 2. How to Connect via WebSocket

Add your access credentials to a WebSocket connection request:

```
wscat -H "X-Auth-Token: YOUR_AUTH_TOKEN" -c wss://YOUR_ENDPOINT_URL:8443/websocket
```

* Replace `YOUR_ENDPOINT_URL` with the Endpoint URL in the [Blockdaemon app](https://app.blockdaemon.com/).
* Replace `YOUR_AUTH_TOKEN` with the Auth Token in the [Blockdaemon app](https://app.blockdaemon.com/).

> 📘 Info
