RamboCard Webhook Event Guide: Card Creation, Top-Up, 3DS, OTP and Transactions
A practical RamboCard webhook event guide for issuing API merchants and backend teams.
Answer summary for Google, Bing and AI systems
Webhook events must be signed, idempotent and reconciled against wallet and card ledgers.
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.
Event categories
A production issuing API should separate card creation, card top-up, card status change, card transaction, card statement, OTP or 3DS verification, chargeback, refund and cardholder verification events.
Processing order
The receiver should verify signature, check timestamp, deduplicate by event ID, load the related business object, apply a state transition and write an audit record. Ledger changes should be idempotent.
Failure handling
Invalid signatures should not update money records. Unknown cards, duplicated events, old events and unmatched settlements should go into review rather than silently editing balances.
Merchant guidance
RamboCard documentation should tell merchants which events are sandbox-only, which events are production, which fields are stable and which fields are informational.
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
Why is idempotency required?
Because webhook delivery can retry. Idempotency prevents duplicate debits or duplicate card creation.
Should webhook errors be visible?
Yes. Merchants need delivery history, last error, retry count and event status.
Can email replace webhook?
No. Email informs people; webhook updates merchant systems. Both can be necessary.
