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.

Eligible 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#.

Things we wrote and said

We were named to the Forbes Fintech 50 list for 2026.

Our founder Darragh joined the Fintech One-on-One Podcast to talk about bank infrastructure.

We wrote about what it's like to work with Increase, and why our engineers handle their own support rather than running a dedicated support team.
