Apideck Unified API
Apideck Connector
Learn how to connect to HubSpot API with OAuth 2.0, handle rate limits, manage lifecycle stages, and avoid common integration pitfalls. Complete implementation guide with TypeScript examples, webhook setup, and solutions to undocumented API quirks.
Learn how unified API providers help software platforms increase integrations, improve customer retention, enhance user experience, and grow their ecosystem while reducing engineering effort and accelerating partner integrations.
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.
Integration partnerships help B2B software companies go beyond simple API connections. Learn how official platform partnerships build credibility, unlock marketplace distribution, enable co-marketing opportunities, and help your product reach the customers who already use the platforms you integrate with.
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.
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.
