Virtual Card API
in Slovakia
Developers in Slovakia use the Eisy virtual card API to put card issuing inside their own product. Create a card holder, run their ID check, issue a Visa or Mastercard virtual card, fund it and read its transactions, all over a REST API with scoped keys and signed requests.

Built on events
Every card event is delivered to your endpoint as a signed webhook and retried until you acknowledge it. A simplified example:
{
"event": "card.transaction.settled",
"data": {
"cardId": "crd_…",
"amount": "12.99",
"currency": "USD",
"merchant": "Netflix.com",
"status": "settled"
}
}Why developers in Slovakia build on Eisy
- •One REST API covers the whole card lifecycle for users in Slovakia: card holder, KYC, issue, fund, freeze, unfreeze, withdraw and terminate.
- •Card details are returned securely on request, so you decide when and where a user sees their card number.
- •Every key has a signing secret and an IP whitelist, and each request is signed, so a leaked key alone is not enough to move money.
- •Webhooks for authorisations, settlements, declines, reversals and refunds keep your ledger in step without polling.

FAQs about the virtual card API
1
Who can use the Eisy card API in Slovakia?
Registered businesses in Slovakia 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
How do I authenticate with the virtual card API?
Exchange your client ID and secret for a one-hour access token, then sign each request with your secret. Every key is tied to an IP whitelist of your servers, and keys can be rotated or revoked from your dashboard.
7
Can I see a card’s balance and transactions?
Yes. The API returns each card’s balance and transaction history, and webhooks push new authorisations, settlements, declines and refunds as they happen.
8
Can the cards pay merchants that charge in EUR?
Yes. The cards hold US dollars, and when a merchant charges in euro (EUR) or any other currency, Visa or Mastercard converts the amount to USD at the time of the transaction.
