Shuttle is the payment layer between software and payment processors: one integration reaches more than 40 processors, for every merchant on your platform. These guides are for platforms adding payments for their merchants, whether that platform is a SaaS product or an AI agent that takes payments by phone or chat. If you are a merchant taking payments for your own business, see [Shuttle for Merchants](/merchants/getting-started/welcome/).

## Two ways to add payments

- **[Embed Shuttle in your product](/platforms/embedded-payments/intro/).** You create each merchant's account, and Shuttle sits inside your product under your brand: onboarding, checkout and a console for merchant staff, as components you embed. This is Embedded Payments for Platforms, Shuttle's main product.
- **[Connect to your merchants' Payment Links accounts](/platforms/payment-links/intro/).** Your merchants have their own Shuttle Payment Links account, and your platform connects to it to create payment links and take payments, with code or with no code at all.

[Choosing an approach](/platforms/getting-started/platform-integration-approaches/) compares the two.

## Where to start

- **[What Shuttle can do](/platforms/getting-started/what-shuttle-does/)**: every capability on one page, whichever approach you take.
- **[Core concepts](/platforms/user-guides/concepts/)**: the five objects that carry almost everything. Once they make sense, the rest of the guides read the same way.
- **[Authentication for platforms](/platforms/reference/authentication/)**: your API key, and how to call the API for each merchant.
- **[Sandbox accounts](/platforms/testing/sandbox-accounts/)**: build and test with no money moving.
- **[Business rules](/platforms/user-guides/rules/)**: what Shuttle will actually do with each request, the same for the screens and the API.
- **[Account sharing](/platforms/account-sharing/overview/)**: let another platform work with your merchants' accounts, with each merchant's permission.
