WHAT IS THE PAYWIZE SANDBOX?
A Complete replica of our production environment - Same endpoints, same request formats, same webhook payloads - but with no real money moving. Test every scenario your integration will encounter.
EVERY SCENARIO. BEFORE PRODUCTION.
Most sandboxes show you success. Ours shows you everything that can go wrong,
so you never find out in production.
Payout scenarios
Success, invalid VPA, insufficient balance, bank offline, daily limit exceeded, duplicate txn, webhook delay, refund reversal
Collection scenarios
UPI collect, customer decline, collect expiry, intent flow, AutoPay mandate create and execute, NEFT virtual account receipt
Connected banking
VAM creation, fund credit webhook, balance check, payout from zero balance queue, webhook delay simulation
Edge cases
Token expiry, rate limit, malformed payload, webhook signature tamper, network timeout, idempotency replay
