<p>The HTTP Provider allows sending requests using HTTP. it does not support subscriptions so you won&#xB4;t be able to listen to events such as new blocks or balance changes. It is usually preferrable using the <a href="_ws_index_.wsprovider.html">WsProvider</a>.
<em><strong>example</strong></em>: <code>javascript
import createApi from &apos;@polkadot/api&apos;;
import WsProvider from &apos;@polkadot/api-provider/ws&apos;;
const provider = new WsProvider(&apos;http://127.0.0.1:9933&apos;);
const api = createApi(provider);</code></p>

The HTTP Provider allows sending requests using HTTP. it does not support subscriptions so you won´t be able to listen to events such as new blocks or balance changes. It is usually preferrable using the [WsProvider](_ws_index_.wsprovider.md).
*__example__*: ```javascript
import createApi from '@polkadot/api';
import WsProvider from '@polkadot/api-provider/ws';
const provider = new WsProvider('http://127.0.0.1:9933');

# Class: HttpProvider
The HTTP Provider allows sending requests using HTTP. it does not support subscriptions so you won´t be able to listen to events such as new blocks or balance changes. It is usually preferrable using the [WsProvider](wsprovider.md).
*__example__*: ```javascript
import createApi from '@polkadot/api';
import WsProvider from '@polkadot/api-provider/ws';
const provider = new WsProvider('http://127.0.0.1:9933');
const api = createApi(provider);
