# OAuth Tokens API

## Renewing Tokens using Refresh Token

If Cotter's SDK doesn't support auto renewal, or if you you need to renew the tokens manually, you can make an HTTP request to Cotter's Server to renew the tokens using a `refresh_token`.

```javascript
curl -XPOST \
-H 'API_KEY_ID: <YOUR API KEY ID>' \
-H "Content-type: application/json" \
-d '{
  "grant_type": "refresh_token",
  "refresh_token": "<REFRESH_TOKEN>"
}' 'https://www.cotter.app/api/v0/token/<YOUR API KEY ID>'
```
