GoSite API
The GoSite developer API, marketed at developers.gosite.com in two families — Business Growth APIs (online presence, listings, lead generation) and Business Management APIs (scheduling, invoicing, payments). Contact Hub, GoSite's CRM surface, is the API listed as available and supports create, read, update and delete over contacts; Sites, Placements, Invoices and Emails are listed as coming soon. Access is approval-gated — a GoSite customer account plus an approved request-access form yields an API key, after which the Swagger reference at api.developers.gosite.com/docs/ is used. As of the 2026-08-22 probe that Swagger host returned HTTP 502 on every path, so no machine-readable contract could be retrieved.
