This page lists every destination system composerID documents, grouped by category, with its coverage status and how the vendor publishes its API documentation. It is for anyone checking whether a system they run is covered, and how far. Coverage status is a public claim, so it is derived from the registry and never hand-edited. Specification mapped means the field mapping is documented against the vendor's own specifications. Documented means the API posture and an indicative mapping are recorded. Roadmap means the vendor documentation is still being gathered. Public vendor docs are an open developer portal; Customer means the documentation is gated behind a customer login or a SKU. ## Vendor Management & Sourcing Specification mapped · Public Specification mapped · Public Specification mapped · Customer Specification mapped · Public Specification mapped · Customer Specification mapped · Customer Specification mapped · Public Specification mapped · Public Specification mapped · Customer Specification mapped · Customer Specification mapped · Public ## Procurement Orchestration Specification mapped · Public Specification mapped · Customer Specification mapped · Customer Specification mapped · Customer Specification mapped · Customer Specification mapped · Customer Specification mapped · Customer ## ERP Specification mapped · Public Specification mapped · Public Specification mapped · Public Specification mapped · Public ## HRIS / HCM Specification mapped · Customer Specification mapped · Public Specification mapped · Public Specification mapped · Public Specification mapped · Public Specification mapped · Public ## ATS Specification mapped · Customer Specification mapped · Public Specification mapped · Customer Specification mapped · Public Specification mapped · Public Specification mapped · Public Specification mapped · Public ## Signature & Contract Management Specification mapped · Public Specification mapped · Public Specification mapped · Public Specification mapped · Customer Specification mapped · Public Specification mapped · Public Specification mapped · Public Specification mapped · Customer Specification mapped · Customer Specification mapped · Public Specification mapped · Public Specification mapped · Public Specification mapped · Customer Specification mapped · Public Specification mapped · Customer ## ITSM / Service Management Specification mapped · Public ## Systems Integrations Specification mapped · Public ## Next steps Plan, preflight and publish: how a decision becomes a valid record in a destination. The five ways composerID reaches a destination, and the minimum a destination must offer. The Intent API and the Manuscript API side by side, and how each authenticates.
