Transaction Data API — Real-Time Card Data | Astrada

Real-time card data from any card, any issuer

Connect your platform directly to card networks. Employees enroll any card — personal, corporate, any issuer — and structured transaction data flows to your platform at authorization. No bank connections. No screen scraping. No re-authentication.

Interactive Demo

See the data flow in real time

Watch real-time card transactions stream through the Astrada API — with 10+ standard fields delivered at authorization, then settled amounts when clearing completes.

Live Transaction Feed

via Astrada API

{
  "descriptor": "Blue Bottle Coffee",
  "transactionHoldAmount": 7.50,
  "transactionCurrency": "USD",
  "acceptor.mcc": "5814",
  "acceptor.city": "San Francisco, CA",
  "network": "VISA",
  "status": "PENDING"
}

Transaction data at the moment of purchase

Bank feeds deliver data 24–48 hours late. Astrada's Realtime Feeds deliver structured transaction data at authorization — the moment the card is used. This isn't a faster version of bank feeds. It's architecturally different: data comes directly from card networks, not aggregated from bank accounts.

Realtime Feeds

Data at authorization

Transaction data arrives the moment the card is used — not hours or days later. Real-time visibility, auth lifecycle tracking, instant policy enforcement.

Clearing Feeds

The smart onramp

Same 10+ structured fields, same persistent connections — delivered at clearing instead of authorization. Start here for immediate data quality improvements, then upgrade to Realtime with a config change when you're ready.

Data Quality

10+ standard fields per transaction

Every transaction arrives structured and normalized. No ML cleanup. No merchant name guessing. Data quality from the source.

What you get from Astrada

Every field is sourced directly from the card network — structured, normalized, and ready for your platform to act on.

The Solution

Real-time card data from Visa and Mastercard, through a single API

Astrada replaces the entire bank feed pipeline — the SFTP servers, the file format mapping, the per-provider PCI configuration — with a single integration that delivers Visa and Mastercard transaction data at authorization.

POST /webhooks — transaction.authorized

Single enrollment

Employee enters card details through your embedded widget. One card, one-time process, data flows immediately.

Batch enrollment

Enroll corporate card programs in bulk. Upload a file of card numbers and enroll an entire team or company at once.
