Apideck Unified API
Apideck Connector
A technical guide to integrating with the SnelStart B2B API. Covers authentication, key endpoints, the certification process, and common challenges developers face when building accounting integrations for the Dutch market.
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.
Your OpenAPI spec is more than documentation. It's a testable contract. This guide covers every type of OpenAPI-driven testing, from contract and variation tests to fuzz testing and CI/CD integration, with tools like Portman, Inspectr, Schemathesis, Spectral, and Microcks.
OpenAPI continues to evolve and sustain a vibrant, interconnected API economy. Here, we define what exactly OpenAPI is, how OpenAPI definitions are structured, explore a real-world OAS example, and look at how OpenAPI is becoming the foundation for AI agent interactions with APIs.
Webhooks let one application push real-time data to another the moment an event happens. Learn how webhooks work, how they compare to APIs and polling, see real-world examples from Stripe, GitHub, Slack, and Discord, and get practical guidance on webhook security, reliability, and testing.
