Discover how Stripe Scripts, Workflows, Custom Objects, and UI extensions help businesses customize logic, data, and operations directly within Stripe.

What if Stripe could work the way your business does

AI was involved at every stage of building Stripe's extensibility SDK, but the story isn't that it wrote code faster. Here's how prototypes, agent-drafted specs, and persistent guidance got ideas into reviewable shape sooner.

AI didn't write our SDK. It changed how we built it.

To minimize failed payments for our users, Stripe targets 99.9995% reliability.  As traffic grew beyond 1.6% of global GDP, this put intense strain on the service mesh.  This is the story of the infrastructure team replacing Envoy, a popular solution, with an alternative architecture.

Building a data plane from scratch: Stripe’s own high-performance distributed proxy

The low-level code that makes a payment go through is getting cheap, fast. What is becoming valuable is the judgment above it: knowing what the money is supposed to do and making sure the code obeys it.

Reading the signals: Helping your AI-built payment integration understand business intent

SaaS platforms don't fit a single mold when it comes to payments pricing. An early-stage vertical software company needs simple, flexible tools to experiment and iterate. A platform moving upmarket needs granular cost control and the ability to offer sophisticated pricing to enterprise customers. And as AI features reshape how platforms monetize, that diversity is only going to increase.

Event destinations are central to Stripe integrations but hard to get right. Event notification handlers encapsulate the setup and wiring, letting you focus on business logic and surface errors at development time instead of in production.

Introducing a better way to process Stripe's thin events

Most of the world's money still moves in batches. A wire submitted at 2pm might settle by end of day, if you made the cutoff. ACH takes one to three business days. Cross-border payments touch correspondent banks, each adding lag and a fee. Stripe has spent over a decade building the Global Payments and Treasury Network (GPTN), a programmable infrastructure for global money movement that batches transfers to reduce cost, nets opposing flows to minimize actual cash moved, and routes through the optimal path between accounts. Under the hood, it's a graph with accounts as nodes, and payment rails as edges.

Extending Stripe’s network with stablecoins

Some microservices are difficult to test because their behavior depends on a long tail of inputs that are hard to model by hand. This post focuses on how to build a repeatable Apache Spark replay harness for testing without creating a second implementation of the service.

Scaling up your microservice testing with Apache Spark—Part 2

Some microservices are difficult to test because their behavior depends on a long tail of inputs that are hard to model by hand. For that class of problem, Apache Spark's massive parallelism and linear scalability can be leveraged to build a regression test harness. That makes it possible to compare old and new implementations, model upcoming rule changes, and quantify impact before a change reaches production.

For product-led businesses, conversion is paramount, so an important consideration is deciding whether to implement synchronous or asynchronous tax ID validation in a checkout flow. One is friendlier for conversion, but the other can keep your business compliant.

Compliance versus conversion: Tax ID validation at checkout

We all know the stereotypes of working at enterprise tech companies: endless bureaucracy and behemoth codebases running on a years-old language version. Most organizations know they should modernize quickly, but haven’t figured out how to build an upgrade path compatible with a large codebase. The recurring cost of upgrading keeps most large JVM codebases trailing behind the latest Java versions.

Modern Java at Stripe: Language upgrades as a service
