# Squarespace Commerce API

**Canonical:** https://apis.io/apis/squarespace/squarespace-commerce-api/  
**Provider:** Squarespace — https://apis.io/providers/squarespace/

Squarespace Commerce API is one of 9 APIs that [Squarespace](https://apis.io/providers/squarespace/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Commerce, E-Commerce, Order, Product, and Inventory. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, an API reference, a getting-started guide, authentication docs, and rate-limit docs.

The complete Squarespace Commerce API as Squarespace itself publishes it — a single OpenAPI 3.1.1 document covering 55 operations across ten resource families: Orders, Products, Inventory, Contacts, Discounts, Transactions, Analytics, Websites, Profiles and Webhook Subscriptions. Harvested verbatim on 2026-08-13 from the download link on the provider's own API reference pages. This is the authoritative contract and supersedes the per-resource splits elsewhere in this repo, which were derived from an earlier, smaller harvest and do not include Contacts, Discounts or Analytics. Note the versioning: resource families carry independent version numbers, so a single integration spans /1.0/, /v1/ and /v2/ paths at once.
