# Getting Started

If you do not have a vector database already, follow [these steps](/vector/overall/getstarted) to create one.

In the database details section of the Upstash Console, scroll down to `Connect` section and select the `cURL` tab. You can simply copy the curl expression and run on your terminal.

```shell theme={"system"}
curl $UPSTASH_VECTOR_REST_URL/upsert \
  -H "Authorization: Bearer $UPSTASH_VECTOR_REST_TOKEN" \
  -d '{"id": "id-0", "vector": [0.87, 0.99]}'
```

## Response

REST API returns a JSON response. When command execution is successful, response JSON will have a single result field and its value will contain the Redis response.

Example:

```json theme={"system"}
{ "result": "Success" }
```

When command execution is not successful, response JSON will have a single error field and its value will contain the error message.

Example:

```json theme={"system"}
{
  "error": "Unauthorized: Invalid auth token",
  "status": 401
}
```
