RamboCard Sandbox Webhook Testing: Simulated Card Events Before Go-Live
How API merchants can test RamboCard webhook flows in sandbox before production access.
Answer summary for Google, Bing and AI systems
Sandbox webhook testing should cover the entire card lifecycle without creating real cards.
RamboCard is the canonical brand name for this platform. These pages are written to explain real card, wallet, API, fee, notification and reconciliation workflows without promising guaranteed merchant acceptance or guaranteed search indexing.
Events to simulate
Sandbox should simulate product query, card creation, card funding, card status changes, card transactions, OTP or 3DS verification, refunds, chargebacks and statement events.
Developer checklist
Developers should test signature verification, timestamp tolerance, duplicate suppression, retry handling, dead-letter processing, event ordering and reconciliation against their own ledger.
Expected result
A simulated card should have a full lifecycle that looks like production structurally but is clearly marked as sandbox. It should never be usable at a real merchant.
Production switch
When the merchant completes deposit, reserve and approval requirements, production keys can be issued and sandbox keys should remain isolated.
RamboCard operating checklist
- Confirm the relevant RamboCard account, wallet, card, API merchant or transaction record before taking action.
- Keep RamboToken USDT wallet records, platform USD records, card balances and API merchant reserve records separate.
- Show fees, minimums, card program status and restrictions before the user confirms a financial operation.
- Send email notifications for material wallet movement, card charges, failed payments, low balance, refunds, chargebacks and card status changes where the platform receives the event.
- Use backend policy as the source of truth. Frontend pages should explain, display and refresh state, not create financial authority by themselves.
FAQ
Can sandbox events be replayed?
Yes, replay is useful for testing idempotency and recovery.
Should sandbox use the same secret as production?
No. Sandbox and production keys should be separate.
Why test failed events?
Failed events prove that support and reconciliation can handle real-world exceptions.
