# Building apps

> Build third-party apps that merchants install on their stores. The full guide lives in its own tab.

Want to build a third-party app that merchants install on their Salesive store — reading and
writing orders, products, customers and more via OAuth?

That guide now has its own tab. Head to **Building apps** for the complete walkthrough:
the OAuth 2.1 + PKCE install flow, the full list of scopes, and how to publish to the
marketplace.
