  note: Union of the OpenAPI JSON fragments Mapp publishes on each endpoint page. Mapp does not serve one consolidated document at a public URL; the tenant-served Swagger lives at https://<your-engage-host>/apidoc/swagger.json and requires a tenant. Operation bodies, parameters, responses, tags, summaries and descriptions are verbatim from Mapp. The swagger/basePath/schemes/securityDefinitions envelope is added by API Evangelist from the published Getting Started guide; no operation content was authored.
