Integration flow
Fund the platform wallet
Use only the supported network and current address shown in the account.
Select a card product
Review the fee, minimum funding, usage notes, and live status.
Issue and fund the card
Wallet deductions and card credits are recorded separately.
Use at a supported merchant
Start with a controlled amount and do not use repeated tests to evade review.
Reconcile transactions
Distinguish authorization, settlement, reversal, refund, and fee events.
Production readiness
virtual card lifecycle automation: Treat every mutation as a financial operation. Persist the request ID, idempotency key, response status, internal ledger entry, and upstream reference before showing the final state to a user.
Rules before launch
Production merchants must follow the current card rules, risk-control policy and account review requirements shown in the signed-in workspace.
FAQ
Why is idempotency required?
It prevents a retry from creating a second card or duplicate card funding operation when the first response is delayed.
Should wallet and card transactions use one balance?
No. The platform wallet and each card account have different balances and transaction lifecycles, even when shown in one interface.
