Webhooks (Professional plan and above)

  • Added rate-published webhooks: get a signed POST to your endpoint within minutes of the RBA publishing the daily rates - no polling required. See the Webhooks guide.
  • New management endpoints (dashboard session, not a Bearer API key): POST /api/webhook-subscriptions (create), GET /api/webhook-subscriptions (list), DELETE /api/webhook-subscriptions/{id} (delete), POST /api/webhook-subscriptions/{id}/test (send a test delivery).
  • Deliveries are signed with HMAC-SHA256 (X-ExchangeRates-Signature: sha256=…); failed deliveries are retried, and a subscription auto-deactivates after repeated failures.
  • Subscription limits: Professional 3, Business 10, Enterprise 50.

​
Fixes

  • Corrected the daily rate-refresh timing so the API tracks the RBA’s same-day publication (previously could lag by a business day).
