- •Pay in US dollars from Vietnam with a Visa or Mastercard card, rather than a local card that may be declined abroad.
- •Keep client budgets apart: one card per client or ad account, so spend never mixes and reconciling is simple.
- •Top up a card when a budget is approved, freeze it to pause spend, and withdraw what is left at the end of a campaign.
- •Charges arrive as webhooks the moment they are authorised and settled, ready for client reporting.

FAQs about cards for ad spend
1
Who can use the Eisy card API in Vietnam?
Registered businesses in Vietnam and elsewhere. You apply for a merchant (business) account, complete business verification (KYB), and your account is reviewed before API keys are issued.
2
Which card networks and currency are supported?
Visa and Mastercard virtual cards denominated in US dollars. Every card is funded from your business USD wallet.
3
Do card holders need to verify their identity?
Yes. Each card holder completes a quick ID and selfie check before cards can be issued to them. You can run this from your dashboard or through the API.
4
How do I know when a card is used?
Webhooks. You receive signed events when a card is issued, funded, authorised, settled, declined, reversed, refunded, blocked or terminated, with automatic retries if your endpoint is down.
5
What does it cost?
Pricing is set per business: a card creation fee, a funding fee (flat or percentage), and termination and decline fees. The fees for your account are shown in your merchant dashboard and before every action you confirm.
6
Will the cards work on my ad platform?
They are Visa and Mastercard USD cards, so they work wherever the platform accepts those networks. Each platform makes its own decisions about which cards it accepts, so try a small charge first.
7
Can I give each client their own card?
Yes. Issue as many cards as you need, fund each one separately from your business wallet, and freeze or terminate any card without affecting the others.
8
Can the cards pay merchants that charge in VND?
Yes. The cards hold US dollars, and when a merchant charges in Vietnamese đồng (VND) or any other currency, Visa or Mastercard converts the amount to USD at the time of the transaction.
