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). ### In this section [**What is Fastn**](https://claude.ai/chat/what-is-fastn.md) — Who the platform is for, what it replaces, and how the core product areas work together. [**Key Concepts & Terminology**](https://claude.ai/chat/key-concepts-and-terminology.md) — Definitions for every core term: customers, connectors, workflows, triggers, CDM, and more. Come back here whenever you hit an unfamiliar term. [**Platform Overview**](https://claude.ai/chat/platform-overview.md) — 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**](https://claude.ai/chat/signing-up-as-a-saas-partner.md) — Create your account, pass the validation pipeline, and get your API keys and dashboard access. [**Your First Integration**](https://claude.ai/chat/your-first-integration.md) — Build a working integration from scratch — create a connector, write a workflow, set up a trigger, and test the full loop. ### Who should read this **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](https://claude.ai/chat/your-first-integration.md). --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://docs.fastn.ai/~/revisions/aj5eaS57qHvafrgYtfbL/fastn-v2/getting-started.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
