2026 Q1 Newsletter

Here’s what we shipped in the first quarter of 2026.

Accounts and Entities

  • We launched our Entity Onboarding Sessions API, which lets you use our hosted authentication UI to collect your customers’ information during onboarding without having to build the KYC flow yourself.
  • Platforms can now set the interest rate for each of their Accounts.
  • You can now create a voided check via the API, which is useful for sharing your account and routing numbers with a counterparty in a familiar format.

Money movement

  • Card authorization controls now support per-card spending limits, with single-use and multi-use cards; per-transaction, per-week, per-month, and per-year limits, giving you fine-grained control over where and how each card can be used.
  • We launched 3D Secure for card authentications, letting you authenticate your cardholders at checkout to reduce fraud and disputes.
  • We launched Push Provisioning, letting your users add their card to Apple Pay and Google Pay directly from your website or native app without typing in a card number.
  • We’re now fully reconciling and passing on all scheme fees from Visa, so the card-network fees on every card payment match the network’s books exactly.
  • We now support attaching up to 999 pages to a single check, for use cases like remittance and lockbox payments where you need to mail substantial documentation alongside the check.

Developer experience

  • You can now restrict API keys to a list of IP addresses, reducing the scope of impact if a key is ever compromised.
  • You can see what an object looks like in the API directly from most Dashboard detail pages via the “Show API representation & events” link, which is handy when debugging an integration without dropping into a terminal.
  • The Event polling API is now generally available — you can poll for new Events instead of listening via webhook, which substantially reduces end-to-end Event handling latency.
  • You can now manually trigger a webhook delivery for an Event from the Dashboard, which makes it easier to debug webhook handlers or replay after an outage on your side.
  • You can now subscribe an Event Subscription to multiple Event categories at creation time, instead of registering a separate subscription per category.
  • Increase SDKs are now available in C#.
