Introduction
Overview of the LinkToAny Unified API — one normalized contract per industry vertical or system category, read and write across every supported platform.
The LinkToAny Unified API exposes a normalized contract per industry vertical (e.g.
Restaurant) or system category (Accounting). Each one defines a set of entities — like
customer, order, and product — with a single schema that works across every supported
platform. You read records from any connected system in that shape, and you write records in
that shape to any system that supports writes.

Schemas are organized per industry vertical (e.g. Restaurant) or system category (Accounting) — each tuned to its domain.
Read + write
The same unified shape is returned on reads and accepted as the write body. No separate DTOs.
Auth handled
LinkToAny manages each platform's OAuth and token lifecycle. You authenticate once, with LinkToAny.
