Overview
Adding cards to a product means integrating an issuing processor's APIs and real-time authorisation webhooks, building a ledger that handles holds and clearing correctly, and designing cardholder experiences. We build that integration end-to-end, so your product can offer cards backed by licensed issuing partners — technology infrastructure for card-program integrations, not issuing itself.
Shivacha provides technology infrastructure for card-program integrations. Card issuing is provided by licensed partners.
Common use cases
- Neobank cardsDebit cards linked to accounts.
- Expense cardsCompany cards inside spend management software.
- Payout cardsInstant access to earnings via card.
- Crypto-linked cardsCards funded from digital asset balances via partners.

Frequently asked questions
Can Shivacha issue Visa or Mastercard cards directly?
No. Issuing requires licensed issuers and network membership. We integrate your product with issuing partners who provide those services.
How fast must authorisation decisions be?
Processors impose strict time limits; our authorisation services are designed for low, predictable latency with fallback behaviour.
Can Shivacha issue Visa or Mastercard cards?
No. Card issuing is performed by licensed issuers and network members. Shivacha builds the technology infrastructure — card management, controls, ledgers and user experiences — that integrates with your issuing and processing partners.
Which card processors do you integrate with?
We integrate with modern issuing processors through their APIs and webhooks. Processor selection depends on your markets, program type and partners.
