About Square
Square makes point-of-sale hardware and software for online and in-person selling across shops, restaurants, and services. Its App Marketplace lists integrations that connect Square's payments, inventory, and customer data to accounting, e-commerce, and operations tools. Developers build apps against Square's APIs, publishing free and paid integrations that merchants connect to their accounts. Specific commercial terms for listings are arranged through Square's developer and marketplace program rather than fixed by category, so builders confirm details during onboarding.
Development starts at the Square developer portal using OAuth and REST APIs, with official SDKs for Java, .NET, Node.js, PHP, Python, and Ruby. The developer marketplace pages describe how to list an app and reach Square sellers. Common integrations synchronize sales, catalog, and payment information between Square and external business systems.
