# Overview

> The nocnoc API v2 — base URL, versioning, request format, and authentication.

The nocnoc API gives sellers programmatic access to products, orders, and packages.

## Base URL

All requests go to the live environment:

```
https://live.nocnocstore.com/api/v2
```

## Versioning

The current version is **v2**. The version is included in the base URL.

## Request format

* All request bodies must be sent as JSON with the `Content-Type: application/json` header. Requests without it will return a `415 Unsupported Media Type` error.
* All responses are returned as JSON.

## Authentication

Every request requires two headers:

| Header         | Value               |
| -------------- | ------------------- |
| `X-Api-Key`    | Your seller API key |
| `Content-Type` | `application/json`  |

```bash theme={null}
curl https://live.nocnocstore.com/api/v2/products \
  -H "X-Api-Key: YOUR_SELLER_KEY" \
  -H "Content-Type: application/json"
```

A missing or invalid key returns a `401 Unauthorized` response. See [Response codes](/api/api-reference/responses) for the full list of error codes.

<Note>
  No IP allowlist is required. The API accepts requests from any origin IP address.
