よくある質問
How soon is a card usable, and where can it be spent?
Issuing returns card details within seconds and the card works immediately anywhere Visa / Mastercard online payments are accepted — commonly AI service subscriptions, ad platform top-ups and cross-border e-commerce.
How do I debug a declined transaction?
Query the transaction history endpoint for that authorization's decline reason code — most often insufficient balance, a restricted merchant category, or a risk-control block. Authorization and settlement events are also pushed via webhooks for reconciliation.
