Welcome to Astrada

Astrada is a bridge between developers and the complex world of payment data. It connects 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 enable earlier settlement for linked cards. See
  Quick Start: Bank Linking.

Where to start

• Getting Started: zero to your first transaction, and how each business event maps to an API call and a webhook.
• Core Resources: the resource model behind the API.
• Authentication: API and SDK credentials.
• Quick Start: Card Enrollment: the card enrollment journey, tiers, and testing.
• Webhooks: registration, retries, and signature verification.
• FAQ: common questions about transaction data, timing, and matching.
