Welcome to the HashDT API Documentation. HashDT offers two card programs — each built for a different funding model — plus a banking program for global accounts and cross-border payments, and a shared Webhook API for real-time event notifications across all programs.

Core Card Program​

A full-featured, wallet-linked card program supporting the complete card lifecycle — cardholder onboarding, wallet-based funding, peer-to-peer transfers, PIN management, spend limits, and transaction history. Cards stay linked to the wallet, so spending draws directly from wallet balance in real time.

Best for: Businesses that need wallet-first funding, peer-to-peer transfers, and granular, API-driven spend control.

Flow: Cardholder → KYC → Wallet → Create Card / Assign Card → Set PIN (For Physical) → Ready to Use

PowerUp Card Program​

A streamlined, recharge-first card program built for speed. Cards aren't linked to the wallet — instead, you recharge the card directly with the amount you want available to spend. Spend limits and PINs are configured during card creation and assignment, so there's no separate setup step.

Best for: Fast card issuance with straightforward prepaid recharge functionality.

Flow: Cardholder → KYC → Wallet → Create Card / Assign Card → Activate Card (For Physical) → Recharge Card → Ready to Use

PowerUp Banking Program​

A unified banking solution for opening receiving accounts, managing beneficiaries, converting currencies, and sending cross-border payouts through supported payment rails.

Best for: Global account management, multi-currency balances, foreign exchange, and cross-border payments.

Flow: Account Provisioning → Accounts & Details → Account Balance → Beneficiary → FX / Payout Quote → Conversion / Payout

Explore PowerUp Banking → for the detailed program workflow.

Webhook​

Shared across all programs. Subscribe to real-time events — card creation, KYC status changes, recharges, transfers, payouts, and more — delivered straight to your endpoint as they happen.
