# Fetch Messages Using REST API

<Info>
  If you do not have a Kafka cluster and/or topic already, follow [these
  steps](../overall/getstarted) to create one.
</Info>

In the cluster details section of the
[Upstash Console](https://console.upstash.com), scroll down the **REST API**
section and and copy `UPSTASH_KAFKA_REST_URL`, `UPSTASH_KAFKA_REST_USERNAME` and
`UPSTASH_KAFKA_REST_PASSWORD` using the copy icons next to them.

We will use a `Node.js` sample code to show how to fetch messages using the REST
API. Our sample will use a topic named `cities` and fetch previously produced
city names from this topic without using Kafka consumer groups.

Replace following parameters in the code snippets below with your actual values.

```js
const address = "https://tops-stingray-7863-eu1-rest-kafka.upstash.io";
const user = "G9wcy1zdGluZ3JheS03ODYzJMUX";
const pass = "eUmYCkAlxEhihIc7Hooi2IA2pz2fw==";
const auth = Buffer.from(`${user}:${pass}`).toString("base64");
const topic = "cities";
```

Following code will fetch city names from `0th` partition of the topic starting
from `1st` offset and print the fetched messages and their offsets to the
console:

```js
async function fetchTopic(topic, partition, offset) {
  const request = {
    topic: topic,
    partition: partition,
    offset: offset,
  };
  const response = await fetch(`${address}/fetch/`, {
    headers: { Authorization: `Basic ${auth}` },
    method: "POST",
    body: JSON.stringify(request),
  });
  const messages = await response.json();
  messages.forEach((m) => {
    console.log(`Message: ${m.value}, Offset: ${m.offset}`);
  });
}

fetchTopic(topic, 0, 1);
```
