WHAT IS PAYWIZE SANDBOX?
A production-like testing environment with the same API endpoints, request formats, and webhook payload structures as production—using simulated transactions instead of live funds.
EVERY SCENARIO BEFORE PRODUCTION.
Most sandboxes focus on basic success scenarios
Paywize Sandbox includes simulated success, failure, and edge-case scenarios to help you test integrations more thoroughly before 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
Edge cases
Token expiry, rate limit, malformed payload, webhook signature tamper, network timeout, idempotency replay
