# Authorization

All requests must be authenticated with an API key that you can obtain by accessing your [Partner Portal](https://partners.clym.io/) account, navigate to the `Integrations / API Keys` section.

For an additional layer of security, you can specify `IP restriction` when creating an API key, so that it can only be used from the specified IP address. You can also specify when this key will expire and no longer be available by using the `Expires on` field.

Once an API key has been obtained, it must be included in the `HTTP Headers` section of all requests, as follows:

```bash
Authorization: Bearer {YOUR_API_KEY}
```

**Example**

```bash
curl --request GET \
  --url https://partners.clym.io/api/portal/domains \
  --header 'Authorization: Bearer {YOUR_API_KEY}'
```
