Square customers, groups, segments, custom attributes, loyalty accounts and rewards, and gift card operations. Generated from the immutable official Square OpenAPI commit f9ff8da9443ade43f823f9100f390b9797c1dcd6 and pinned to Square-Version 2026-07-15. Enroll one production seller connection with OAuth or a bearer access token; this pack matches and executes only against https://connect.squareup.com, not the separate Square sandbox origin. Every leaf read is uncached, every mutation is grant-off and requires approval, all JSON responses preserve unsafe integers as decimal strings, and nested int64 or provider-keyed-map request contracts use bounded raw JSON. Documented cursor collections walk automatically unless a raw JSON request makes safe cursor composition impossible. Deprecated routes, OAuth token lifecycle, unsupported multipart uploads, and executable storefront snippets are excluded. No Square object is declared as a task, note, or user-work project Source.
