QuickStart

Audience: Everyone, read once before going anywhere else. Reading time: ~8 minutes. Prerequisites: None. You'll learn: The stack-level architecture, the five core concepts (Gateway, Connectors, Orchestration, Overledger Firewall, Fusion Rollup), and the glossary used throughout the rest of the docs.

Info, Chapter under construction

The Quickstart is being rewritten against the upcoming OpenAPI specifications for the relaunch. We're holding the concrete curl walkthrough, request/response shapes, and code samples until those specs publish, so that every command in the chapter is copy-paste accurate on day one rather than drifting between draft revisions.

What you can do in the meantime

While this chapter is paused:

• Understand the surface. Chapter 1: Overview & Concepts and Chapter 4: Overledger Gateway cover the architecture and the Gateway's resource model.
• Pick a Flow App to try. Chapter 6: Orchestration, Flow Applications describes what Flow Apps are and how the Prepare-Sign-Execute pattern works.
• Connect a wallet to the Fusion Rollup. Chapter 7: Accounts & Signing and Chapter 8: Fusion Rollup cover signing surfaces and the multi-ledger rollup details respectively.

If you need a guided integration before the Quickstart is ready, contact your account team.

When this chapter ships

The full Quickstart will return alongside the OpenAPI publication and will cover:

• Sign-up and credential setup against the API Clients page.
• A first authenticated call to the Gateway.
• A first multi-DLT RPC call via the Connectors endpoint.
• Driving a built-in Flow App session end-to-end.
• Switching between testnet and (where contracted) mainnet.
