# Quickstart

Get sandbox credentials and make your first Payroc API call.

Create a sandbox account at developers.payroc.com, generate an API key, and make your first request.

> **Every request needs a fresh Idempotency-Key**
>
> Send a unique UUID v4 per request; reusing a key replays the original response instead of charging twice.

```bash
curl https://api.payroc.com/v1/payments \
  -H "Authorization: Bearer $PAYROC_API_KEY" \
  -H "Idempotency-Key: $(uuidgen)"
```
