Simulating money flows

Drive payments, refunds, disputes and payouts by hand.

Every state change a real merchant can experience is triggerable from the environment's ledger tools — and each one emits the same webhook a live account would.

Action Effect Events emitted
Create payment Adds a succeeded charge and a balance transaction payment.created, payment.succeeded
Refund payment Full or partial refund against a charge refund.created, refund.succeeded
Open dispute Moves the amount into dispute, holds the funds dispute.created
Submit evidence Attaches evidence, dispute goes under review dispute.updated
Close dispute Won (funds returned) or lost (funds deducted) dispute.closed
Run payout Sweeps the available balance into a pending payout payout.created
Settle payout Marks the payout paid payout.paid

Funds maturity

Sandbox funds follow a T+2 availability model, like production: a payment lands in pending, becomes available after two simulated days, and only available funds can be paid out. Advance the clock from the ledger view instead of waiting.

Raw event simulation

Any event from the event catalog can also be fired directly with a synthetic payload — useful to test handlers for cases that are awkward to reach, such as invoice.payment_failed.
