Test mode

Your TEST keys work against a sandbox that answers exactly like the live API, so you can build and test the whole flow without moving real money.

How test mode works

• Calls signed with a npk_test_... key are test calls; responses carry "mode": "TEST".
• Test balances are separate from live ones. Switch your dashboard between LIVE and TEST at the top right.
• Nothing is sent to a real processor, and no real money moves.

Simulating results

1. Payins

   Open the checkout link of a test payin: it shows Simulate successful payment and Simulate failed payment buttons. Either one fires your webhook with a real signature.

2. Payouts

   Test payouts succeed within about a minute, except an account_number ending in 0000, which fails, so you can test your failure handling.

3. Claims

   Claim your test payins on Claim Settlement in TEST mode and watch the balances move.
