 ### 2. Adjust subscription parameters
 
 One can configure the request/subscription parameters to customize the received price updates. A sample request is shown below:
 
-```json
-  client.send({
-    type: "subscribe",
-    subscriptionId: 1,
-    priceFeedIds: [1, 2],
-    properties: ["price"],
-    chains: ["solana"],
-    channel: "fixed_rate@200ms",
-  });
+```js
+client.send({
+  type: "subscribe",
+  subscriptionId: 1,
+  priceFeedIds: [1, 2],
+  properties: ["price"],
+  chains: ["solana"],
+  channel: "fixed_rate@200ms",
+});
 ```
 
 Here:
