Everything you need to go from signup to a working embedded integration — what Fastn is, how it works, and your first end-to-end build.
Fastn is an embedded integration platform for SaaS companies. You embed it into your product, and your customers get native integrations with the apps they already use without you building or maintaining the overall infrastructure.
This section walks you through the platform from first principles to a working integration.
Diagram needed: High-level visual showing: Your SaaS Product → Fastn (Connectors, Workflows, AI Agents) → Third-Party Apps (Slack, Shopify, Xero, HubSpot).
What is Fastn — Who the platform is for, what it replaces, and how the core product areas work together.
Key Concepts & Terminology — Definitions for every core term: customers, connectors, workflows, triggers, CDM, and more. Come back here whenever you hit an unfamiliar term.
Platform Overview — How the platform is organized. Covers the four main sections (Home, Integrations, Activity, Settings), the onboarding stepper, and the architecture underneath.
Signing Up as a SaaS Partner — Create your account, pass the validation pipeline, and get your API keys and dashboard access.
Your First Integration — Build a working integration from scratch — create a connector, write a workflow, set up a trigger, and test the full loop.
SaaS companies evaluating or onboarding onto Fastn. If you're a developer, product manager, or technical lead and you need to offer integrations to your customers — start here.
If you already have a Fastn account and want to jump straight to building, go to Your First Integration.
