Cards Payments API Dashboard

Improvements to the API and sandbox


We recently released a few new features that will make it easier to build new experiences in production, improve reliability, and get started developing in sandbox.

Webhook retries

We recently added a new option to receive events through reliable webhooks. Using the new batched delivery setting will result in us delivering multiple events in a single payload and we will continue to attempt delivery for 1 hour or until we receive a success status call. Now you don’t need to worry about missing important events if your app has brief downtime. (docs)

Rejected incoming payment event

Now there’s an event for when an incoming ACH is returned. The declinedIncomingPayment.Created event makes it simple to understand when an incoming payment didn’t complete so you can surface that information to your users. For example, a business may be trying to send one of your customers a large ACH payment that gets rejected by their bank for insufficient funds, or they may have inputted the routing and account numbers correctly but had incorrect information elsewhere. (docs)

More card activity data

We’re adding more metadata to card transactions so you can set up more useful programmatic authorizations, and create more informative user experiences and reporting. Authorization requests, authorizations, and purchase transactions will now contain the following attributes when available:

  • Payment method: Manual, Swipe, Contactless, ChipAndPin, Stored, Other.

  • Digital wallet: Google, Apple, Other.

  • Merchant location: City, State

  • Verification method: Address, CVV2, AddressAndCVV2.


Sample data in sandbox

To make it easy and quick to understand what a functioning banking implementation looks like with Unit, we've created sample data that you can load into your sandbox. Just download and use Postman to import the Unit API Starter Collection to populate your sandbox environment with test data. (docs)
