Welcome to Astrada

Astrada is an indispensable bridge between developers and the complex world of payment data — connecting directly to major card networks for real-time transaction visibility, and to financial institutions via Plaid for bank account data. Once a card is enrolled or a bank account is connected, transaction data flows into your server in real time.

Two connected data sources, one transaction feed:

• Card transactions — direct connections to Visa, Mastercard, and American Express surface
  authorization messages as they happen, not just clearing data days later.
• Bank transactions — connect a cardholder's bank account to unify bank-side activity (fees,
  transfers, payroll) onto the same feed, and unlock earlier settlement for linked cards. See
  Integration Guide.
