API Modernization

Our team moves working-but-aging Stripe integrations onto Stripe’s current primitives, incrementally and without taking payments offline. We’ve done it for Dave.com, Rocket Lawyer, Elastic Path, and more — for some of the largest companies in the world, serving millions of users, in very high-profile environments. When a user is stuck on older Stripe code and can’t reach the features Stripe keeps shipping, that’s the work we do.

What modernizing unlocks

For an AE, this is the work that opens the rest of Stripe’s catalog to an existing user. The biggest unlock is Stripe Checkout Sessions, Stripe’s newest checkout and the one it keeps investing in. Moving onto it turns on 125+ payment methods (wallets like Apple Pay, Google Pay, and Link, plus Buy Now, Pay Later and local options) and shows each buyer the ones most likely to convert. It brings in Stripe Tax, adaptive pricing in the buyer’s own currency, SCA handled automatically, and built-in upsells, cross-sells, and promotions, most of it switched on through configuration. Once a product is on the current stack, adopting Stripe Billing, Terminal, and the latest Radar tooling no longer takes a re-platform.

How we do it

Migrations on a live payments system are unforgiving, so we run them incrementally and observably. Our team inventories every call site, sequences the low-risk high-traffic paths first, and shadows the riskiest cutovers (run the new call, compare it against the old, switch only once the comparison is clean). We move the webhook listeners with the call sites and decommission the legacy path once the new one is verified. The common migrations are ones we’ve run before: the old Charges API onto PaymentIntents, hand-built checkouts onto the Payment Element or Checkout Sessions, older Connect charge patterns onto the current model, and saved-card flows onto the modern setup.

Working with your Stripe team

We work at enterprise scale and partner with the Stripe account executive, Professional Services, and solution architects when they’re involved. Modernization is often the unlock that lets a user adopt more of Stripe, so bring us in when an account is ready to move and needs the hands to do it.
