Everything you need to integrate with the Stripe API
In-depth articles and integration guides
Stripe's API spans hundreds of endpoints across Payments, Billing, Connect, Radar, Issuing, Treasury, and Tax. This guide breaks down each API surface, when to use it, and how Apideck's upcoming Stripe Billing connector fits into the accounting integration picture.
When Stripe added /llms.txt to their docs, most write-ups noted it as another company "embracing the AI era." They missed the interesting part. Buried inside is an instructions section no other company has built — Stripe programming what AI tools say about Stripe. Here's why that matters and what it means for your API.
How Apideck auto-generated a 229-tool MCP server from an OpenAPI spec using Speakeasy, deployed on Vercel with dynamic tool discovery at 1,300 tokens. A walkthrough of the stack, the hosting tradeoffs, and the hard-won lessons from shipping serverless analytics.
Vertical SaaS companies like Toast and Shopify now earn most of their revenue from embedded payments, lending, and banking. Real data on revenue, take rates, and the fintech stack that makes it work.
Webhooks let one application push real-time data to another the moment an event happens. Learn how webhooks work, what a webhook endpoint is, how they compare to APIs and polling, see real-world examples from Stripe, GitHub, Slack, and Discord, and get practical guidance on building receivers, security, and testing.
Revenue financing and embedded lending platforms use banking, accounting, and ecommerce data together to onboard and underwrite SMBs in hours, not weeks. Here's how.
A developer's guide to stablecoin APIs in 2026: Stripe, Circle, Fireblocks, Paxos, and the x402 agentic payment protocol. Covers API surface, custody models, gas fee abstraction, GENIUS Act compliance, and machine-to-machine payment flows.
TL;DR: MCP tool definitions can burn 55,000+ tokens before an agent processes a single user message. We built the Apideck CLI as an AI-agent interface instead:an ~80-token agent prompt replaces tens of thousands of tokens of schema, with progressive disclosure via `--help` and structural safety baked into the binary. Any agent that can run shell commands can use it. No protocol support required.
For 15 years, developer experience meant optimizing for humans at a terminal. That model is increasingly incomplete. A growing share of API traffic is generated by AI agents that read docs, make decisions, and retry failures autonomously. This is the same discipline as DX applied to a new consumer. Call it agent experience, or AX.
AI agents can now hold virtual Visa cards, execute purchases autonomously, and settle transactions with other agents. Every major payment network is racing to build the rails. Here is what it means for spend management and the fintech founders building the next layer of financial infrastructure.
A category overview of the companies building ledger, payment operations, and money movement infrastructure, covering Formance and Modern Treasury through to Fragment, TigerBeetle, Column, and 20+ others shaping this space.
Everything you need to know about integration with Xero in 2026: top apps by category, how to choose the right one, and what it takes to build a Xero integration into your own product.
Master the fintech API landscape by balancing direct integrations with unified solutions. This guide explores the trade-offs between payments, banking, and accounting APIs to help you scale without the maintenance nightmare.
Direct integrations work until maintenance costs outpace development. Learn when fintech teams should shift from building custom connections to leveraging data aggregators and unified APIs for scalable integration infrastructure.
Learn what accounting integrations are, why they're essential for modern SaaS products, and how to build them. This guide covers common use cases, implementation approaches, and what to look for in an integration solution.
API integration is the process of connecting two or more software systems through their APIs so they can exchange data.
A Unified API aggregates many APIs in the same software category, making integration easier with a standard endpoint, authentication, and normalized data. This results in a consistent developer experience with less integration hassle.
Learn how to quickly set up a MCP Server in Cursor and unlock AI’s potential with the Model Context Protocol (MCP). Standardize LLM integration with external tools.
Software Development Kits (SDKs) are very common throughout the development landscape. Most API providers offer SDKs to help support specific programming languages and app development paradigms, making them an integral part of an overall developer support strategy. Below, we'll define what SDKs are, explore sample SDKs, and see how SDKs differ from APIs.
Monetizing an API in large organizations is like vices amongst teenagers: They talk a lot about a given vice, but very few are actually doing it. Put yourself in any large and well-established organization which has published APIs and you’ll find something similar with monetisation. Unless that organization is API-first there is constant talk of how to “sweat” APIs to get some return on their investment, but very little success in making it happen.
Nowadays, Developer Experience (DX) is essential for software products. Akin to User Experience (UX), DX instead focuses on improving the developer's journey, reducing hang-ups, and encouraging success throughout their programming experience.
