# Sandbox basics

A real, stateful test world — not a mock.

The sandbox is a full copy of the merchant experience running on test data. Payments settle, invoices are issued, disputes open and close, payouts pay out — all with fake money, on a real ledger.

## What is isolated

- Its own test merchants, one per environment
- Its own credentials (`test` client id / secret, `sb_at_test_…` tokens)
- Its own webhook endpoints and delivery logs
- Its own rate-limit counters

Nothing in the sandbox can read or write live data, and no email is ever sent to a real customer.

## Instant verification

Sandbox payout onboarding completes immediately: no documents, no bank details, no real identity. Bank management and live-access UI stay hidden until you switch to live mode.

## Seeding

*Seed data* fills an environment with a plausible merchant: products, prices, customers, a handful of settled payments and one open dispute. *Wipe data* clears objects but keeps the environment and its installs.

## Resetting

Resetting an environment clears data, installs and webhook logs and re-issues the test merchant. Use it when a broken test state is faster to throw away than to repair.
