# Quickstart

Whichever integration you pick from the [Introduction](/get-started/introduction), the first three steps are the same.

<Steps>
### Get an API key

Generate one in [Lighthouse](https://lighthouse.beamcheckout.com/) (or [Playground Lighthouse](https://playground-lighthouse.beamcheckout.com) for sandbox). See [Authentication](/get-started/authentication).

### Register a webhook

So Beam can notify you of payment outcomes. See [Webhooks](/webhook-overview).

### Test on Playground first

Then switch to Production. See [Playground Environment](/playground).
