# Quickstart

> Make your first authenticated request.

## Create a key

Open Developers in your company console, select the sandbox environment, and create a key with `balance:read`. Store it on your server.

## Read your balance

Set `PLANE_API_KEY` to your sandbox key in your server environment, then run:

```bash theme={null}
curl 'https://business.planewallet.org/api/v1/balance' \
  --header "Authorization: Bearer $PLANE_API_KEY"
```

The response contains `available`, `held`, and `environment`. The environment is determined by the API key. Money values are decimal strings.

## Next steps

To issue a card, create a cardholder, get the available product catalog, request a quote, and submit an operation using the quoted total. Follow the operation until it reaches its final status.

A successfully accepted operation is not proof that a card has been issued. See [operation lifecycle](/operation-lifecycle).
