Sandbox Overview
What is Sandbox?
Sandbox is a safe, self-contained place to see and interact with Wingspay's test data — test cards, test wallets, and simulated webhook delivery — without touching anything real. It's not a "test mode" toggle on your account; it's a separate space with its own fixed, fake dataset that stays fake permanently, so what you see here always matches what a fresh integration would see.

sk_test_…Sandbox doesn't issue its own credentials. A Test key is the same API key you already create in Auth, with the Test environment selected — Sandbox is where that key gets used against fake data, not where it's created.
