​
Cards

Use card 4111-1111-1111-1111, cvv 999, and any future expiry date (for example, 12/30). The rest of the info is not important. For 3DS use 111111.

​
Pay By Bank

Select the Aerobank test bank and log in with one of these Aerosync sandbox credentials: Your customer email must be a valid email address and you must have access to it for OTP. Never enter real bank credentials in sandbox. See Aerosync test banks for more scenarios.

​
Crypto

Crypto payments in sandbox run on the Base Sepolia testnet, so they use free test funds, not real money.
  1. In your wallet (for example, MetaMask), select the Base Sepolia network: chain ID 84532, RPC URL https://sepolia.base.org, block explorer https://sepolia.basescan.org. Don’t use Base mainnet (chain ID 8453).
  2. Get test ETH from the Superchain Faucet. It requires a free sign-in, and the ETH can take a few minutes to arrive.
  3. Optionally, get test USDC from the Circle Faucet by choosing Base Sepolia.
  4. At checkout, choose Crypto and either connect your wallet or send the exact amount shown to the deposit address.

Testing Webhooks

If the payment amount matches a row below, you will receive the listed webhooks.
Sandbox is lenient about restrictions: outcomes that restrict a customer in production (geo, KYC failure, underage, the KYC-vs-profile name check, card or bank name mismatch) do not stop a sandbox checkout, so you cannot trigger those restrictions in sandbox. Use the $1.13 amount below to exercise your customer.restricted, customer.unrestricted and checkout.terminally_failed handling instead.
