2026 Q1 Newsletter

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

## Accounts and Entities

- We launched our [Entity Onboarding Sessions API](/documentation/hosted-onboarding), which lets you use our hosted authentication UI to collect your customers’ information during onboarding without having to build the KYC flow yourself.
- Eligible platforms can now set the interest rate for each of their Accounts.
- You can now [create a voided check](/documentation/api/exports#create-an-export.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](/documentation/api/cards#card-object.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](/documentation/3d-secure) for card authentications, letting you authenticate your cardholders at checkout to reduce fraud and disputes.
- We launched [Push Provisioning](/documentation/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](/documentation/webhooks#event-polling) 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#](https://github.com/increase/increase-csharp).

## Things we wrote and said

- We were named to the [Forbes Fintech 50](https://www.forbes.com/sites/brandonkochkodin/2026/02/19/the-future-of-business-to-business-banking-fintech-50-2026/) list for 2026.

- We wrote about [what it’s like to work with Increase](/articles/support-that-doesnt-scale), and why our engineers handle their own support rather than running a dedicated support team.
